How to Test for a Faulty Circuit Breaker
Circuit breakers are used to protect the electrical system in your home from overheating and getting overloaded. A breaker that flips often may be faulty or the breaker could be functional and the problem could be coming from somewhere else. If your circuit breaker will not reset and the load terminal doesn’t put out voltage then you probably need to replace the circuit breaker.
If you suspect a circuit breaker is faulty then you can do a circuit breaker test to help you determine if it is not working or if the trouble is in the internal wiring.
One test is to use a reliable voltage tester or voltage meter to measure the electricity flowing through the circuit. If the voltage is low then the breaker is not allowing the current to flow through correctly.
Another way to test the circuit is to turn off and unplug all devices that are associated with the circuit then see if it will reset. Once it is reset proceed to turn on each item individually and see if the circuit stays on.
It is important to turn off the circuit breaker and keep all electrical devices off while you reset the breaker because if there is a short in the breaker a surge of electrical current can flow all at once causing an arc that may start a fire or cause electrical burns and serious injury.
If the circuit stays set, you may want to look at individual appliances, cords or light fixtures that are connect to the circuit breaker in order to get to the source of the problem.
