    How to run a small wire into a waterproof enclosure?

    03th Spt 2021

    In a cold and wet atmosphere, every electronic circuit is a potential failure site. What you want and need to ask yourself for every electrical system is: Should the connection be able to connect and disconnect, or could it be semi-permanent or long-lasting? It is significantly more difficult than it appears to make electrical equipment that is impermeable in a moist environment. The solar-powered SeaCharger can float in freshwater, operate a thruster engine, and recharge its batteries. Each element of a weatherproof connector might cost up to. A succession of watertight electrical components will follow. Some options Urethane seems to be the greatest cable coat material. Considering EPDM and Neoprene as alternatives. When you reconnect the wire, please ensure your adhesive adheres well to the wire as well as the container. Urethane seems to be the suitable choice to use for cable jackets (or polyurethane). Although urethane-jacketed wires could be difficult to identify, they are well worth the search effort. For a wide range of applications, the 3M Marine Glue 5200 is a fantastic pick. Pulling the wire out should be done with as little force as possible. Urethane seems to be the right material to use for cable jackets (or polyurethane). This material is extremely durable, easy to bind, and waterproof. EPDM, as well as neoprene, are therefore viable options. I wouldn't even consider utilizing wire with a PVC coating! Water flows down the wire if somehow the cable is severed. Even though the cable-to-enclosure barrier is intact, a tear in the cable jacket could allow water to pour in. The metal threads inside of the cables could also carry water. A bulkhead penetrator seems to be a connector that permits a wire to "penetrate" an enclosure's walls without being securely attached to them. A lovely aluminum frame version will be available from Blu Robotics, and there are other DIY variants available on the web. A penetrator isn't as long-lasting as a cable connected to an enclosure. It has a nut for attaching to the enclosure's walls and also an O ring for sealing against this. An aluminum frame version is also available from Blue Robotic. The "wire gland" or "rope grip" is really a sort of penetrator which does not necessitate bonding. The wire is sealed with a rubber cover that cracks down upon the cable. They're most commonly employed in exterior applications wherein electrical cables must be passed through a wall socket. This is a water-resistant conduit for wires with a thickness of 5 millimetres or smaller. The Basic Penetrator is available from Blue Trail Technologies in standard parts. The Simple Penetrator is still a weatherproof circuit that eliminates the need for messy and error-prone planting. With simple dependability and minimal cost-it's inexpensive and simple to use. If a wire is cut, any sort of penetrator would not prevent water from leaking down the specific cables and then into their container. It is feasible to connect your wire to a penetrator in a way that this will not occur.   There are two types of water resistance: one that is watertight and the other that isn't. In the case of such a damaged connection, waterproof connections offer the additional benefit of keeping liquid from entering the enclosures. They could also be utilised for "undersea" or "deepwater" purposes. You'll probably need to have a connection that is actually meant for a plunge into the sea if users would like it to be dependable throughout the longer term. Waterproof connections can be found on eBay for such a reasonable price. "Micro-Circular" connections are some of the more popular waterproof connectors with a range rating. To verify compliance, it is best to use interconnects from the same manufacturing company. If needed, they may reproduce when submerged. The Cobalt line of undersea connections was designed by Blue Trail Technologies. These are substantially less expensive and smaller than any waterproofing connection, but provide as much capability as a 600-meter deep specification. Waterproofing the cable connectors in the irrigation canal is amongst the most important aspects of any repair or maintenance. Using super glue to secure them would not function! Your valves WILL fail when users don't water-proof their joints. Household drainage systems rarely use 2-wire circuits, as they've become more common. Use specialized water-proof splice connections, which can be purchased anywhere at a hardware store, to create the junction. The procedures outlined here are for cables with a power of 24VAC or less. Greater voltages should never be used with them. It is most probable that a wire will be small in the future compared to splitters, which is why a box makes things easier to locate as well as maintain. Various styles or even kinds are accessible. "Nut" or "Wing" Form Water-Proof Twist-On Connections A screw-on-style wire connection has been used by the majority of pros nowadays. 5 connectors are required for each and every 3 interconnections. A single junction can readily merge three wires simultaneously, but much more than three at such a moment will become more complex. If a cable connection has already had cables soldered simultaneously, don't try and add another one. Remove the entire connection & attempt again when a wire seems weak or comes out. Replace the connection and replace it with a new one, as part of the sealant will likely be lost. Unless the cables still fall out from a second attempt, you're most likely using the incorrect connection diameter. Water-resistant "nut" or "wing type" connectors are low-cost and easy to use. A large number of these low-cost connections come with no specifications. You'll have to delete and discard some bad joints if we make a lot of these. A large number of these low-cost connections come with no specifications. Please follow the steps that come only with connections, since they were written specifically for the adapters you purchased! To use a single socket, you could simply solder three wires simultaneously, but adding upwards of three becomes more complicated.

    How to connect two wires in a junction box?

    03th Spt 2021

    Junction boxes are plastic or metal boxes that are used in houses or apartments for connecting wires. The connection within the box is known as a branch circuit and usually signifies the end of a cable run. A junction box needs the wire easy to access as all wires are connected in the building. You just have to remove the covering of the junction box for repairing or for additional wires to add. Junction boxes also prevent the wire from damage due to rain or any other environmental damage. This box also protected wires from illegal tampering.   Some of the basics of junction box wiring   Usually, a junction box in a house or a factory is used to connect single power to multiple outlets. For instance, a junction box may contain one wire power source that is connected to multiple power sources. They are generally made up of hard metal or plastic and usually sizes between two and a half to 3 ½ inches long.   The material of a junction box depends on whether your junction box is supposed to support any weight. Like metal junction boxes can support light fixtures on the other hand plastic junction boxes cannot support this weight. Another additional benefit of using a plastic junction box is that they can easily be installed than metal ones. However, a junction box is made to just cover wire splices be it metal or plastic.   Why must splices be in junction boxes?   All wire splices should be enclosed within a junction box in a house or a building to meet the electric code. But sometimes wire splices are missed and that causes fire hazards. Any wire, which is exposed to the environment, can be dangerous. Especially wire splices that are bared are prone to accidents because they can be tripped over, distort or expel sparks that can be hazardous for both children and pets. Junction boxes can be a good alternative to ignore a hazard. They are helpful for wire slices because they also allow the professionals to locate the wire splice area.   How to join the wire to the junction box?   The junction box is used to create all wire connections in the home called splice. The junction box is often attached to an electrical outlet. By making splices in a junction box the risk of electrical accidents occurring from connecting wires coming in contact with flammable articles diminishes considerably.   Once a new junction box is connected to the ceiling, other walls are ready to be connected to the wires. To attach a new junction box in your house, first, turn off the main power circuit breaker box of your home where you are going to install a new junction box.   Before attaching the main junction box, check with a plugging circuit tester into an electrical outlet of a room and connect the same circuit to ensure that the power is correctly off before attempting to add more wires to your home.   Then take a screwdriver and a hammer to knock out the hole in a wall where you want to install a junction box to insert a cable.   Try to insert the wire through the whole of a cable on an electrical box of the outlet. You can also try to push it to the wall towards the junction box. You can pick whichever technique to insert the wire in the junction box. On the junction box, use a fishtail to pull the end of a cable through the cable clamp.   Try to pull up the electrical cables as much as six inches out from the electronic box junction box. Finally, cut the excess wire with the help of a wire cutter.   Inject another length of electrical cable from junction box to electrical outlet. Run the end of the electrical cable true cable clamp on a junction box and route the cable through the wall outlet. Again, with the help of fish tape pull the end of the cable into the electrical box. Try to leave a 6 inches electrical cable on both ends of the box and cut the rest with the help of wire cutters.   Now cut 3 inches from the outer insulating jacket of the electrical cable with the help of a utility knife to reveal the color code combination of insulated wires within it.   Then the color code is separated with the help of wire strippers. Make sure you strike 3/8 inches of the insulating jacket.   Grip the end of the white wire to the new fixture of white wire in the junction box. To make it even, try to trim the excess wire with the help of wire cutters. Now twist the wire clockwise and screw on the wire nut. Make sure it is covering the ends of bare metal. In the same way, connect the green and black wire to the new junction boxes wires respectively.   Connect all the wires on the same day with the wire nuts. If the wires are going to join electrical outlets with a terminal screw then turn the black wire anticlockwise around the brass color terminal screw and tighten the screw with the screwdriver. In the same way, the white wire goes anticlockwise around the silver-colored terminal screw and tightens the screw with a screwdriver.   Finally, push down the junction box cover onto the junction box and screw them. Tighten the screw with a screwdriver to secure the junction box cover.       Conclusion   We know that electricity and water are opposite to each other. It is important to cover all our main circuits with weatherproofing junction boxes to prevent electrical accidents. This junction box protects our electrical appliances from being damaged by lightning, electrical short circuit, fire, or any other natural calamity. Therefore, it is advised to cover your main circuit with a junction box.

    Which is better terminal box or junction box

    27th Aug 2021

    Electrical junction box is this small metal or plastic box which enclosure housing electrical connection. It is a part of an electrical conduit wiring system in a building that shields the electric connection from weather and accidental electric shocks. It is designed in-ceiling floors or concealed behind a panel particularly in commercial or domestic buildings. Sometimes they are embedded in plaster walls so that only the cover is visible from outside.   junction box is also included in building terminals for the joining of wires. A wall-mounted box is used to support switches sockets and connecting wires. These types of junction boxes are mainly used in large items such as a piece of street furniture. In a country like the UK, this junction box has mainly been termed a cabinet.   Junction boxes are the main part of the protection of the circuit system where circuit integrity has to be granted for emergency or power lines or the wiring between a nuclear reactor or a control room. In such a situation, to cover the junction box fireproofing is necessary as incoming or outgoing cables to prevent unexpected fire or a short circuit inside the box.   How junction box work?   The junction box work as a mutual meeting spot for electric wires that connect before moving onto the main circuit. These box guards are hot, neutral, grounding copper wire and some other secondary functioning lightning electric wires.    All junction boxes are covered, installed correctly, and in compliance with the applicable building quotes. They cover and protect the wire from smut, dust, and dampness from getting inside the box.   Make sure you turn off the power before working with the junction box. The hot wire is risky for a person who is working with a junction box.    What is the terminal box?   Terminal boxes are the insulated blocks that secured two or more wires together. They are mainly used in commercial places like factories to secure and terminate the wire. In their natural form, they consist of many individual terminals which are designed in long strips. The biggest advantage of using terminal boxes is the cost they incited during installation. They are the cheapest connector. It can save your time as the process of connecting wire is not as elaborated as the others. They can be effortlessly fitted using a screwdriver. You can also easily connect or disconnect while maintaining or troubleshooting. The terminal boxes are all multi-level blocks that can reduce the space up to 80%.   These terminal boxes include the multi-level of circuits with that single box. Most of the terminal boxes are made up of copper that is used to play fishing also wire. As the wires are made up of copper, their checks loosening due to changes in the expansion rate.   It also helps in decreasing corrosion which is caused by electrolytic action between two different metals. As it is made up of copper which is a good insulator of electricity it increased safety by grounding isolating and protecting other components from electric shock circuits. They are available in finger-safe Connections to prevent electrical shock.   How to select a terminal or a junction box Both terminal and junction box are used in house electrical components and two facilitating wired.   Selection: While selecting a junction box or terminal box adequate protection and the correct size must be the priority of the selector. When you consider the protection, professional rating, material type, and the system should be their determining factor. Some of the additional features like battery compartment, doors bays, and inner panels can be the factors for choosing the type of box.   Types of materials used in the junction box or a terminal box: the persistence and the amount of stability of a terminal or a junction box depend largely on the material used in making them. most of the boxes are made of the materials classified as their polymers or metals Polymers: They are non-metals, that have various properties depending on the materials they are made up of. Some of the materials used for making the polymers are ABS, fiberglass, polycarbonate, polystyrene. ABS has a good chemical and crepe resistance property made up of hard rigid and inexpensive thermoplastic polymer. But sometimes, they are prone to fracturing under excessive heat. Polystyrene is used for dimensional stability rigidity and hardness as it is easy to fabricate. Fiberglass is a strong durable and reinforced polymer. Polycarbonate is also an excellent material that had a great impact on strength and can be molded in tight tolerance, but can be moderate to chemical corrosion.   Metal: Metal is generally dependent on its conductivity both in electricity and heat than the other material types. Steel is used because of its durability and malleability for the enclosure of the box. Rather than using standard steel, stainless steel is used in the inclusion of boxes as they are a resistant and lightweight material. Sometimes in place of stainless steel, aluminum is used as they are also lightweight, more conductive, and less expensive material compared to stainless steel. They are also resistant to oxidation.   Shape and size of junction or terminal box   The shape and size of the junction or terminal box depend on the design of the component being used in making the box. They are generally T- shaped or rectangular made from materials that are available in various sizes. The size and shape also depend on the configuration of sealing and mounting styles. The outer box may come in standardized dimensions that can be stacked for assembly or build to particular specifications according to the requirement of the customers.   Sum up   The function and the durability of the terminal and the junction box are almost similar to each other. But when it comes to its safety, the junction box is the most appropriate. The professionals always recommend using or install a junction box rather than a terminal box. This is because to avoid overload of electricity which is the main cause of potential electric fire in commercial buildings or house.

    What is the purpose of an electrical junction box

    27th Aug 2021

    Wire connections are encased in electrical boxes, often known as junction boxes. They aid in the prevention of short circuits, which can result in fires. This guide explains the various varieties of electrical boxes, as well as their materials and applications. They come in a variety of forms and sizes to match your needs. Learn the distinctions so you can be sure you're selecting the correct box for your project.   The National Electrical Code (NEC) and municipal building rules govern the types of electrical boxes used in specific applications and how they should be erected. Electrical boxes must be covered with matching electrical box covers, according to their specifications. You can't hide them behind drywall, panelling, or any other type of wall covering. The conductors must be able to move freely inside the box.   Before you begin any electrical project, check with your local building inspector and secure the necessary permissions. Always have your work assessed by local codes once you're finished.   Junction Box in Action The junction box is where electrical wires come together to link before continuing on their journey. The hot, white, and grounding electrical cables are protected in these boxes, containing other wire shades for the secondary functions and lighting.   The main electrical panel to the junction box encased Romex wire runs. The brand name Romex refers to a nonmetallic encased electrical wire that is often used for residential branch wiring. The wires are connected to the original Romex wire and then spread to the other fixture boxes. The wire gauges (diameters of wires) should all be the same. All junction boxes must be adequately covered, installed, and by local building codes. The cables are protected by the lid, keeping dirt and dust out and preventing moisture from entering the box.    Electrical Boxes Come in a Variety of Shapes and Sizes   • Handy Box: Attached to a wall's surface. Light switches or receptacles may be present. Ideal for places where installing behind-the-wall is difficult or impossible. • Junction Box: Wires only connect in a junction box; they never link to a switch, receptacle, or fixture. Allows circuits to securely branch and split in multiple directions. • New Work Box: Installs directly on studs or joists or between two studs with a bar hanger before drywalling. • An old work box is sometimes known as a "remodelling box." After it has been hung, it is installed on drywall. It comes with clamps and is perfect for installing new outlets on pre-existing walls. • Metal and nonmetallic outdoor boxes are available. Gaskets, sealed seams, and waterproof covers protect wiring from the weather.     All electrical boxes must have box covers, according to the electrical code. Watertight exterior covers are required.   When working with a junction box, safety comes first. Before working on a junction box, make sure the electricity is turned off. You don't want to be the unfortunate recipient of a hazardous hot wire.   Finally, punch a hole in the box to allow the wires to pass through. Secure the Romex wiring that enters into the box with a cable clamp, then cap wires inside the box with wire nuts. If you're having trouble twisting the wires together, wrap black to black and white to white with needle-nose pliers before adding the wire nut. After that, secure the box by grounding it.   Sizes and Shapes of Electrical Boxes   An electrical box's shape can assist you in figuring out what it's for. Electrical boxes come in a variety of sizes to accommodate various installation requirements. The most typical electrical box is rectangular in design. It is available in metal or nonmetallic units and houses a single electrical switch or outlet. Gaskets, sealed seams, and waterproof covers protect wiring from the weather in these boxes.   Two devices are housed in a square electrical box, commonly known as a "double-gang box." They'll have a single outlet/switch or two outlets/switches on the inside. The round or octagonal box in the ceiling stores lights, fittings or safety devices. These are used to power lights, as well as smoke and carbon monoxide detectors. Heavy fixtures, such as ceiling fans or chandeliers require a ceiling box. Choose a ceiling box that is designed to support the additional weight.   Materials for Electrical Boxes   Metallic and nonmetallic materials are used to make electrical boxes. Aluminum, steel, and cast iron are the most common metals used in metal boxes. PVC or plastic are used to make boxes that are not composed of metal.   Metal Boxes:   • Metal junction boxes are required by many municipal building codes because they are sturdy and provide long-term performance. • Choose from a variety of junction box sizes to pick the right one for your project. • Use for sensitive indoor applications, such as in an unfinished basement with a conduit.     Boxes made of plastic or PVC:   • These boxes are low-cost and straightforward to set up. • Electrical boxes made of plastic can be hidden beneath walls. • Use with nonmetallic cable only.     Tips & Tricks for Installing Electrical Boxes   Before beginning any electrical project, make sure to check with your local building inspector. They'll make sure you're obeying the rules. • If you're building a new house, draw a floor plan and make sure you have enough electrical boxes to fit all the light switches, outlets, and fixtures you'll need. Ascertain that the electrical box sizes you select are appropriate for the locations where they will be used. • Use a stud finder to locate studs when working in finished areas. Make sure they don't get in the way of a new box being placed. • To designate cutting lines, trace an outline of the box on the wall where it will be mounted.

    What is an MCB and its use in a home?

    17th Aug 2021

    A miniature circuit breaker is an electromechanical device that protects an electric circuit from overheating. An electrical issue caused by an overload or a short circuit is referred to as a short circuit. We used to defend against over-current with fuse wire (in fact, we used to sell it!) back in the day. The concept was simple: an over-current would physically "blow" the fuse wire by quickly heating and melting it. MCBs expand on this functionality by not being destroyed during an over-current and so being reusable. It's also considerably easier to use, with the simplicity of 'on or off switching' for the circuit isolation. They are much safer to use and operate because the conductor is then housed within some plastic shell. It's worth noting that MCBs don't protect people against electrical shock generated by 'earth leakage.' RCDs and the RCBOs are the devices that perform this service.   Kilo Amperes, Amperes, and Tripping Curve are the three main features of an MCB.   Overload Current Ratings - Amperes (A) When too many appliances are connected to a single circuit, they use more electrical current than the circuit and cable were designed to handle. It may happen in the kitchen if the kettle, dishwasher, electric range, microwave, and blender are used simultaneously. The MCB on this circuit cuts electricity, keeping the cable and terminals from overheating and catching fire.    Kilo Amperes - Short Circuit Rating (kA)   Short circuits are caused by a failure in an electrical circuit or appliance, and they can be even more harmful than overloads since the scale and speed of overcurrent are on a different scale. When the live and neutral conductors are connected directly, this happens. The electrical current rushes around the circuit in a loop without the resistance supplied by regular circuit integrity, multiplying the amperage by thousands of times in moments. Because of the link between standard voltage (240v) and typical residential appliance power ratings, short-circuit over-current should not exceed 6000 amps. However, when employing 415v and big gear in commercial and industrial settings, 10kA rated MCBs are required. The most Prospective Fault Current that the MCB may withstand while still disconnecting the circuit is shown by these ratings.   Tripping Curve An MCB's 'Tripping Curve' allows for real-world, and sometimes necessary, power surges. To overcome the inertia of large motors in commercial applications, large machines typically require an initial burst of power over their average working current. The MCB allows this small spike, which lasts only seconds because it is safe to do so for such a short period.     Typical Uses for Domestic MCBs   While each installation is unique and should always be planned by a fully licensed professional electrician on-site, most household wiring schemes follow the following guidelines: Lighting circuits rated at six amps Large lighting circuits rated at ten amps, albeit these are becoming less common in home settings as technology and trends shift toward lower-energy lighting sources like LEDs. Both 16 amp and 20 amp are often used for immersion heaters and boilers, depending on the power rating. Ring Final - 32 Amp The power circuit are referred to as "sockets" in technical terms. Cookers, electric hobs, and tiny showers require 40 amps. Electric showers and hot tubs with a 50 amp - 10 kW power supply.   There are five uses for MCBs that you may not be aware of. A well-established electrical system is one of the most crucial needs for the effective functioning of your home, factory, or workplace. Every piece of domestic equipment and machinery consumes a significant quantity of energy, necessitating safety precautions when using electricity. Power surges can cause voltage changes that are exceedingly harmful and dangerous.   Miniature circuit breakers are small devices that act as control agents in the event of a power outage. When it detects an overload or a power surge, this device shuts down the electrical system. Various varieties of MCBs can be used in your homes and businesses, depending on the nature of the electrical applications. Miniature breaker circuits are ideal for dwellings and the buildings with limited electrical infrastructure. Here are some applications for MCBs that you may not have considered.   1. Electrical Panels in the Home To protect dwellings against overload, miniature circuit breakers are utilized. They are more reliable and safer than fuses because of their ability to manage massive amounts of electricity. One of the most significant advantages of an MCB is that it ensures that electrical energy is distributed evenly across all devices.    2. Lights Every home has a sophisticated lighting system. These can help with the efficient distribution of electricity throughout the house's lighting systems. Compared to regular light bulbs, fluorescent lamps, for example, use a lot of electricity to operate. MCBs come to the rescue in this situation. MCBs also aid in the maintenance of light bulb quality and safety.   3. Applications in Industry In both small and big scale companies, miniature circuit breakers can be adequate safety mechanisms. In an ideal world, most industrial gear would require a power supply of up to 30 kA. In this instance, replacing old fuses with MCBs is required. MCBs play a critical function in commercial facilities, ensuring the efficiency of applications and installations by optimizing energy flow. Hotels, supermarkets, and bakeries all make use of them.   4. Heaters MCBs are a reliable safety option, particularly if you have heaters installed in your home or office. Heaters, in general, are prone to excessive voltage swings since they consume such a large quantity of electricity from the main supply. These instances can be avoided with the proper installation of a small circuit breaker. Miniature circuit breakers come in various shapes and sizes, each capable of handling a specific power load.   5. Ground Fault Trip Mechanism When the live wire does touch with a transmitting surface that isn't part of the circuit system, a ground fault occurs. When there is a failure in the circuit, the rate of current flow rises. An MCB starts its magnetic tripping mechanism and rectifies the circuit system at this point.

    What is the effect of overloading in the circuit

    17th Aug 2021

    You've generated an electrical circuit overload if you've ever plugged in too many holiday lights, turned on a vacuum, or turned on a space heater only to have the lights or appliance abruptly turn off. The safest technique is to limit your electrical usage in the first place to avoid overloads.   What Is an Overload in an Electrical Circuit? When you draw more electricity than a circuit can safely handle, you have an electrical circuit overload.   What Causes Electrical Circuit Overloads? Electrical circuits are only capable of handling a certain amount of current. Wiring, a breaker, and gadgets make up a circuit. The total LOAD on the circuit is determined by the amount of power used by each gadget when it is turned on. When the circuit wiring's rated load is exceeded, the circuit breaker trips, cutting power to the entire circuit.   If the circuit did not have a breaker, an overload would cause the circuit wiring to overheat, melting the wire insulation and causing a fire. Because different circuits have varied load ratings, some can supply more electricity than others.   Overloaded Circuit Symptoms A breaker tripping and cutting off all power is the most evident indicator of an electrical circuit overload. Other signs may be less obvious: • Dimming lights, particularly if they dim when you use appliances or turn on extra lights. • Outlets or switches that make a buzzing noise. • Surfaces that are warm to the touch, such as outlet or switch covers. • Burning scents coming from switches or outlets. • Burned plugs and outlets • Power tools, appliances, or devices that don't seem to have enough juice.   Circuit Mapping in Your Home Learning which circuits power which gadgets are the first step in preventing electrical circuit overload. After you've laid out the basic circuit layout, you can calculate each circuit's safe load rating to see how many objects you can connect to it. If your kitchen lights fade when you switch on your toaster oven (power-hungry equipment), and that the circuit capacity is nearing its limit. Mapping the circuits can also reveal whether new circuits are required to satisfy the household's usual demands.   Circuit mapping is straightforward (if tedious): Take a notepad and a pencil with you. Turn off one of the breakers with the number 15 or 20 stamped on the end of the breaker switch by opening the door to your home's service panel (breaker box). Make a note of where the circuit is in the panel on the pad so you can find it later.   After that, take a tour through the house and test out all of the lights, ceiling fans, and plug-in appliances. Make a list of everything that doesn't have power, as well as the room it's in. Also, try each outlet with a voltage or receptacle tester, or even a plug-in light or lamp, and make a note of those that don't work. You don't have to go around the whole house to find each circuit. If your electrician was thorough, there might be labels next to the breakers indicating the circuit sections.   Circuit Load Calculation Your circuit map will show you which circuits power which devices. Now you must figure out how much energy the devices consume. You'll need a quick education in electrical energy to do so. Watts are the units of measurement for electricity; a 100-watt light bulb consumes 100 watts. The product of voltage (volts) and amperage (amps) equals a watt: 1 watt Equals 1 volt x 1 amp Add the wattage of all the devices on each circuit to obtain the total load on that circuit. The wattage of light bulbs and many little gadgets is labeled. To calculate the watts of a device that only gives you amps, multiply the amp value by 120 (the voltage of typical circuits). Include any permanently connected gadgets to the circuit and any plug-in appliances that aren't used frequently.   Compare each circuit's total wattage to the load rating for that circuit. Fifteen amps are rated for circuits with “15” breakers. One of these circuits has a maximum load rating of 1,800 watts: 1,800 watts = 120 volts x 15 amps   You will overload the circuit if you use more than 1,800 watts on it, and the breaker will trip. Circuits with “20” breakers are rated for 20 amps and can handle a maximum load of 2,400 watts: 2,400 watts = 120 volts x 20 amps   For each circuit, compare the overall wattage (how much electricity you're consuming) with the load rating. A 15-amp circuit servicing lights and outlets in a living room, for example, may provide 500 watts for lighting, 500 watts for the TV and cable box, and 200 watts for the sound system, totaling 1,200 watts. If you plug in a 700-watt vacuum when the TV, stereo, and lights are turned on, you'll surpass the circuit breaker's 1,500-watt rating, causing it to trip and turn off the electricity.   Solutions   The maximum load on each circuit isn't the best benchmark to aim towards. It's desirable if the usual load on a circuit exceeds 80% of the maximum (rated) load for a margin of safety. The safe load target for a 15-amp circuit is 1,440 watts; for a 20-amp circuit, the safe load target is 1,920 watts. If your circuit calculations show that you're taking more watts from a circuit than the safe load number—or if you're often overloading the circuit by exceeding the rated load—there are a few strategies to lessen the load on the circuit to avoid overload:   • Move plug-in appliances to a less-used circuit (use your mapping and circuit calculations to identify circuits that have plenty of available wattages). • Avoid turning on too many things at once. Turn off the TV and sound system when vacuuming, for example (you won't be able to hear them anyhow). • Replace incandescent or halogen light bulbs with energy-efficient LED (preferred) or CFL (fluorescent) bulbs to reduce lighting loads. • New circuits for high-demand devices should be installed.
