How You Can Test Your Circuit Breaker Properly with a Multimeter

A multimeter is a great supporting tool that you need to provide when you are going to test the performance of your circuit breaker. This is a handy device that helps you in having to check the voltage in electrical circuits. Below are given few simple steps that you can follow in using a multimeter to check your breaker.

First, you have to open your circuit box. You may find some breakers here so that you can determine which one you are going to check first. Usually, your house gets powered in different portions with each of those breakers' powers. By taking a look at the label you can easily notice which breaker can handle the power.

Second, by the certain breaker that you want to check you have to turn off all the appliances and lights that are being powered. It becomes necessary to prevent any serious problems such as damaged appliances and lights or even fire.

Third, you need to always think about your safety. You should always put a pair of rubber-soled shoes on and ensure that the area near your circuit box is completely dry. Besides, you need to be very careful with puddles that you might find on the ground. Before testing your breaker, you need to check the surrounding environment so that you can prevent the risk of electrical shock. Circuit Breaker Manufacturer produces good quality circuit breakers.

Fourth, around your breakers, you need to unscrew the metal frame. Simply unscrew it use your screwdriver and you can set it aside. Behind the metal frame, you will see wiring that runs through the breakers and also the breakers themselves.

Fifth, you can even set your multimeter to Volts AC. In-home maximum wiring systems use alternating current, so the Volts AC setting let the multimeter correctly read the current. In testing the voltage of battery-powered electronics DC is usually used.

Sixth, to the terminal screw of the breaker you have to touch one prong of the multimeter. Then, another prong can be touched on the breaker to the ground screw. Your multimeter will tell you about the readout on how much electricity flows through your breaker. You need to immediately replace your Vacuum Circuit Breaker well if your meter does not read anything.

Principle of Residual Current Circuit Breaker and its Advantages

We all are aware that electricity has become an indispensable component of our lives but the main fact is it comes with its hazards to human life and property. Electrocution and fire being are the two major risks closely related to electricity. When it comes to the protection of electrical circuits the RCCB Residual Current Circuit Breaker is an important safety measure. It is a current sensing device, which automatically measures and disconnects the circuit whenever there is a fault that occurs in the connected circuit or the current exceeds the rated sensitivity.

RCCB is particularly helpful in instances of sudden earth fault that aims at protecting an individual from the risk of electric shocks as well as electrocution and fires. The presence of RCCB makes sure that in such types of cases, the circuit trips immediately and the person gets protected from an electric shock.

Principle behind RCCB

On the principle of Kirchhoff’s law, Hager Residual Current Circuit Breaker generally works, which says that in a circuit the incoming current must be equal to the outgoing current. Thus, RCCB compares the difference in current values between live and neutral wires. Ideally, the current that flows to the circuit from the live wire needs to be the same as that flowing through the neutral wire. In case there is a fault, the current from the neutral wire gets reduced and the differential between the two is known as Residual Current. The RCCB is triggered to trip off the circuit when there is a spotting of a Residual Current.

One thing that ensures that the reliability of RCCB is tested is when a test circuit is included with the Residual Current Device. The current starts to flow through the test circuit when the test button is pushed. On the neutral coil of the device there occurs an imbalance. So the RCCB trips and supply is disconnected which then checks the reliability of RCCBs.

Advantages of RCCB

• Protects against voltage fluctuation as it includes a filtering device that guards against transient voltage levels
• When the rated sensitivity is exceeded, it automatically disconnects the circuit
• Both cable and busbar connections is offers the possibility of dual termination
• Against earth fault as well as any leakage current ELCB Residual Current Circuit Breaker
• Provides protection
