What Is The Difference Between RCB And RCCB?

28th Apr 2022

While electricity has many benefits, it also comes with numerous risks, including the risk of electrocution and fire. Because of these hazards, reliable electrical safety devices have been designed to protect people from these hazards. 

It is important to learn about these safety devices and to use them wisely and regularly. Using these devices will help you avoid accidents. 

The safety switch is a device that senses low leakage currents and interrupts the flow of electricity when other devices fail. The most common kind of RCD is a circuit breaker, which is connected to the live wire in your home’s electric circuit. 

A safety fuse is a device that will protect you if it fails to detect a hot wire to ground fault. A power surge can cause a fire, and this is why this device is so important.

An electrical safety device can prevent a fire or electrical explosion by protecting guests from harm. This type of device is used in most public buildings and is also available in some commercial and industrial settings. 

When it comes to electrical safety devices, people always get confused between the terms like RCB, RCD or RCCB. While the purpose of all these devices is safe, they are different from one another.

People mostly get confused between RCB and RCCB and use the terms interchangeably. If you want to know the difference between these two electrical safety devices, follow this article.

What Is RCB?

The RCB is also known as the Residual Current Device. It automatically disconnects a circuit whenever it detects an abnormal amount of current. This device protects people from electrical electrocution and shock caused by contact with electricity. The main benefit of an RCB is that it can operate with other devices. Its use is very important. If you’re looking for a dependable circuit breaker, you should consider an RCB.

RCD includes all the electrical safety devices that help break the current if there is any leakage. It is a broader term and includes devices like RCCB and RCBO, etc. An RCD is a safety tool that disconnects the electricity supply if the amount of residual current increases above a certain value. This is beneficial because people handling electrical equipment often come into contact with the active or neutral conductor. An RCD also prevents fatal electrocution. There are two types of RCDs, high-sensitivity and low-sensitivity. High-sensitivity RCDs are used in residential settings.

The device cuts off the electricity automatically when a fault occurs. This is a safer and more efficient solution than circuit-breakers or ordinary fuses. An RCD protects against both electrocution and fire. The RCD is most effective when an earth fault is present and prevents the flow of electric current to the earth. It’s important to know the difference between Type A and Type B RCDs.

What Is RCB Used For?

Residual Circuit Breakers are a type of circuit breaker that protects against fires, electrocution and earth faults. The main purpose of a residual circuit breaker is to prevent electric shock or electrocution by interrupting the flow of electricity. These devices are most useful in instances when unexpected earth faults occur. These faults can occur when people touch a live wire, which may result in an electrical shock.

An RCB can be equipped with both overvoltage and overcurrent protection. These circuit breakers can be adjusted to avoid electromagnetic interference. The setting current of the overvoltage protection release can be altered. The RCB is ideal for homes and businesses. If you have a large commercial complex, you may want to install multiple RCBs. These breakers can prevent electrical shocks and fires.

What Is RCCB?

An RCCB, also known as a residual current circuit breaker, disconnects a circuit when it detects an abnormal amount of residual current. This type of circuit breaker is typically used in three-phase installations with high-current loads. RCBs are designed to work with other devices, including fuses. They come in 3 poles and 4 pole versions. The difference between each one is the amount of residual current sensing. 

A 30mA tripping level will provide maximum shock protection. A 100mA tripping level will still provide a degree of protection. But a 300mA tripping level will never be recommended for shock protection. In general, it is only used for fire protection.

RCCBs are an essential safety device for your home and workplace. The device works by comparing the values of the currents in the live and neutral wires. This device is able to sense an imbalance in the current and immediately disconnect the power supply. This device also provides complete electrical protection along with MCB. 

How Does RCCB Work?

The working principle of residual current circuit breakers (RCCB) is very simple and intuitive. It operates by tripping off the circuit when the residual current changes by just a small amount. An RCCB can respond in only 40 milliseconds and is a very effective device for protecting against electric shock and leakage. 

This device operates on Kirchhoff’s law that the incoming and outgoing currents should equal each other. It compares the currents of the live and neutral wires to detect a fault. When a fault is detected, the incoming and outgoing currents decrease by the amount of the faulted circuit. This is called Residual Current, and when an RCCB detects this, it trips off the circuit.

The sensitivity of the RCCB is high. Humans can sustain electrical shocks of 30 mA. A higher current can be fatal. But this protection is limited to normal power loads. A fault in the electrical circuit can result in an electric shock. It is therefore important to protect your home with an RCCB to protect it. It is a safety device that is able to identify any electrical malfunctions before they can happen.

What Is RCCB Used For?

RCCBs protect your electrical system from earth faults. They are also known as earth leakage circuit breakers or residual current devices. In this article, we’ll discuss the different uses of an RCCB. For starters, you should know that these devices are often installed on circuit breakers and switchboards. The main function of these devices is to detect and shut off electrical current in a circuit.

An RCCB protects against electrocution and electric shock. It works by sensing the difference between the current values in the neutral and live wires and trips the circuit if the imbalance exists. Together with the MCB, an RCCB is an important part of your electrical protection. 

An RCCB works by sensing the difference in current values between the incoming and the outgoing neutral. When it detects a fault, it will shut off the electricity supply. This is called a “residual current .”Hence, the device will shut off your electricity in the event of a transient voltage. This way, your electrical system will not be damaged. Further, an RCCB can also protect you against electrocution.

What Is The Difference between RCB and RCCB?

There is not much difference between RCB and RCCB as both are electrical safety devices and help to reduce the risk of serious harm from electric shock. When there is leakage in the ground wire, these devices break the current to avoid any dangerous situation.

RCB, which is also known as RCD, is a general term used for residual current devices. RCCB is a type of RCD. RCCB stands for residual-current circuit breaker. RCB is a wider term, and RCCB is a part of it.

In countries, RCB is also known as RCCB. These two terms are often used interchangeably. The only difference between the two terms is that RCB is an umbrella term used for residual current devices, and RCCB is a type of residual current device.
