Six Essential Steps When Checking A Circuit Breaker
A circuit breaker is a device that cuts down the power at home if there is too much current flowing in the wiring. It can be basically be found inside a breaker panel box. You must know where to find this breaker panel box, along with the circuit breakers that are responsible for every item at home running on electricity. Inspecting circuit breakers at home is easy. It is a deed that has to be done three or four times each month to make sure the family is safe. Prior in checking the circuit breakers, you have to turn off all the electricity at home. Knowing how to check the circuit breaker can help save precious time and money. The following steps will provide you a guide when inspecting a circuit breaker.
Step 1: Initial Inspection
The first thing to inspect is if the breaker is not tripped. If the switches at home are in OFF state, turn them into ON state. If it solves the problem, the breaker is working fine. If it does not, you must do some more tests to know the problem.
Step 2: Checking a Short-Circuit
You have to switch the breaker OFF, then turn it ON again. If it doesn’t stay on or if you hear some humming sound, you have to pull the wire out of the circuit breaker then do it once more. If this is the case, there could be a possible problem when it comes to wiring.
Step 3: Inspecting the Panel
The wire in the breaker has to be removed. With the use of Voltmeter, inspect the active breaker. If there is a sign of voltage, then there breaker is working, and your problem is probably in the breaker panel, which means you may not change it. If there is no voltage, it means that the problem is in the breaker.
Step 4: Inspecting the Breaker using the Wiggin’s Tester
You can use the Wiggin’s Tester, or a light bulb linked between the screw and the ground in the panel. If the tester has problem running, then the breaker is broken and need to be replaced
Step 5: Inspecting the Breaker by Wiring Changes
One more method to check any problem in the breaker is to place the wire to another breaker and see if it will work. This is the best test and the most efficient. You have to ensure that both breakers are off when moving the wire, then turn on the new breaker. If the new breaker faces problems, then it means that the wiring is defective. If it works fine, then the other breaker was the problem.
Step 6: Breaker Inspection using Ohm-meter
The last test that you can do is to use an Ohm-meter. To do this, you must turn off the breaker and remove it. Then, turn it back on and use the Ohm-meter to conduct testing between the screw and the bus clip. If the reading is above five ohms, it means that the breaker is faulty and needs to be replaced.
Ground Fault Circuit Interrupters (GFCI) help protect people from electrical shock in homes, offices, hospitals, schools and outdoors.The great thing about GFCIs is that they protect you whether or not your wiring is grounded.
