What Is Distribution Box Consists Of?

28th Apr 2022

The distribution box is an electrical device for centralizing power and handling faults. The basic parts of a distribution box are a switch, a wire, and a shell. 

The different types of boxes have different functions and internal structures, but they all share a common purpose: to help people manage and oversee the power in their homes or office. 

The distribution board is the final point of electrical power distribution throughout the entire building. The main cable enters the board and is distributed via breakers to the secondary circuits. 

Proper power distribution is critical to the safety of appliances and electronics and ensures the optimal performance of appliances. A distribution board is a central electrical supply system used to distribute power. 

It consists of switches and fuses to separate the main power supply into subsidiary circuits. To better understand a distribution board, read on to learn more about its components.

What Is A Distribution Box?

A distribution box is a critical component of the electrical distribution system. It regulates the flow of electricity throughout the distribution board, preventing circuit overloads and potentially dangerous situations. 

The distribution box is also referred to as a panel board. It is an electrical control center that divides power into subsidiary circuits. It contains protective fuses for each circuit. The shell is made of materials that do not allow corrosion. The wiring should be of high quality to prevent accidents and maintain safety. The internal components should be organized and installed firm to prevent any damage. The distribution box should also be easy to operate and maintain.

Most distribution boxes are fitted with a solid case, which protects the interior components. The wiring and parts are mounted inside the box, reducing the risk of them being damaged. A distribution box has a watertight and airtight cover, which allows easy access to the interior components. This allows easy inspection of the components. It also makes replacing components easier and more convenient. 

What Is The Function of a Distribution Box?

The distribution box is an essential component of a larger system. It regulates the flow of electricity through a distribution board and can prevent overloaded circuitry, which can be dangerous. 

A distribution box is a panelboard that distributes electrical power throughout a building. The main current comes into the box and is then distributed to other components. The circuits in the distribution box are separated by manual switches. The purpose of these boxes is to ensure that the power supply is safe. 

Distribution boards are usually installed at two hundred millimeters from the floor and must be kept away from water. In addition, distribution boards should be out of reach of children. It should also be placed away from cooking appliances, as they can be fire hazards. 

Internal Components of a Distribution Box

A distribution box is a set of electrical components used to send and stop electricity. These are comprised of two parts, the enclosure and the electrical circuit. The enclosure is the main part, which includes switches, meters, and a power circuit breaker. The latter is more useful for large-scale electricity usage. Let’s take a closer look at the various components of a distribution box.

  • Circuit Breaker

The circuit breaker is a component of the distribution box, which controls one single circuit throughout your home. This device has two rows of numbered switches. When the switch is set to ON, power will flow through the circuit. When the switch is set to OFF, it will block the flow of power. The breaker will display information related to the switch numbers. The main receptacle on the distribution box has a main breaker switch, which turns off all the power to your home. The circuit breaker is the most important component of a distribution box. It is the only barrier between a circuit user and a potentially fatal electric shock. It should be properly rated, tested frequently, and never be bypassed. 

  • Leak Current Protection Switch

Leakage current protection switch is a component of distribution boxes, which is used to prevent high voltage from reaching the user’s equipment. The device detects leakage and shuts down the electrical system, protecting both the device and its user. This device can be useful in industries where high voltage can damage equipment. The leakage current meter is an essential component of the distribution box because it measures the current flowing to the earth. The leak current protection switch is a key component of distribution cabinets. Its main function is to prevent electric shocks from occurring when a live conductor is touched. The switch has three functions: short-circuit protection, overload protection, and current-on-off. 

  • Dual Power Auto-Switch

The dual power auto-switch is a device that controls the power flow between two separate sources. It has many functions, including current leak protection and an automatic transfer switch. In addition, it has other safety features such as short-circuit protection, overload protection, and current on/off. This switch is a component of distribution boxes. It provides a safe way to manage the energy supply for your home.

  • Surge Protector

A surge protector is an electrical device that diverts high-voltage currents away from appliances and wiring. Just like water pressure on a hose, too much electrical pressure can damage appliances. A surge protector is a component of a distribution box that prevents this kind of situation.

  • Watt-Hour Meter

The watt-hour meter is a component of a distribution box that measures the amount of electrical power flowing through a circuit. This device consists of a small electric motor and a counter that measure the current of the circuit. A watt-hour metric is based on the fraction of the current flowing through the circuit that the motor can measure. The speed of the motor’s rotor is proportional to the amount of current flowing through the circuit. 

  • Voltmeter

A voltmeter is an electrical instrument used to measure voltage. A voltmeter has a series and parallel connection. A voltmeter reads the difference in electric potential at two points in space. In a distribution box, a wattmeter is connected to one terminal of the fuse, while an ammeter is connected to the other.

  • Isolators

The most common isolation device used in distribution boxes is the three-post isolator. It has three load insulators, with the middle one containing the tubular contact and flat male contact. The middle post insulator rotates in reverse to close the isolator, and it also has a switch for manual or motorized operation. Its function is to protect the current from overcurrent or short circuits.

  • Busbars

Busbars are flexible power distribution components used for lighting and other electrical functions in a distribution box. These devices have a flexible design to allow for workstations to move around machinery and equipment. They can also house expandable track lighting from a single power supply.  

  • Identification Labels

Identifying labels distribution box is very important. Identification labels are a quick and convenient way to identify cables, and they can be positioned in convenient locations. Heat-shrink tubes and wraps are two common types of cable and wire markers. These materials are easy to install and are very durable.
