Using a Multimeter to Properly Test Your Circuit Breaker

An electric breaker is an electrical switch that operates automatically and is specifically made to safeguard electrical circuits from the damage of any type in the event of a short circuit or overload. The main responsibility of the circuit breaker is to locate any fault situations and break continuity to halt power flow. In most homes, short circuits are the main reason why fires start.

The multi meter is terrific supporting equipment that you should have available while you are testing the functionality of your circuit breaker. This practical tool makes it simple to verify the voltage in electrical circuits. In addition, it aids in determining if the circuit being tested is employing AC (alternate current) or DC (direct current). You may use this specific tool to examine whether or not the circuit breakers in your system are functioning properly. Here are some easy procedures you may use to inspect your breakers using a multi-meter.

You must first access your circuit box. Considering that there may be breakers present, you must choose which one to examine first. Typically, a distinct part of your house is powered by each of those breakers. By looking at the label, you can quickly determine which breaker is responsible for handling which electricity. If you are unable to locate this information, you should immediately label your breakers.

The second step is to shut off all the lights and appliances that are connected to the 100 amp breaker you want to inspect. Preventing any significant issues, such as broken lighting, appliances, or even a fire, is crucial.

The third thing you should consider is your safety. Put on some rubber-soled shoes and confirm that the vicinity of your circuit box is entirely dry. Additionally, you should use extreme caution around any puddles you may come upon on the ground. As soon as you mop them, check to see if the ground or floor is indeed dry. To reduce the chance of receiving an electrical shock, you should properly inspect the area before testing your breaker.

The fourth step is to remove the screws holding the metal frame on your breakers. Simply remove it with a screwdriver, then put it away. Wiring that passes through the breakers as well as the breakers themselves is located behind the metal frame.

The fifth option is to set your multi meter to AC Volts. Since house wiring systems often employ alternating current, the multi meter's Volts AC preset enables accurate current readings. Typically, DC is used to check the voltage of electronics that run on batteries.

Sixth, you must connect one of the multimeter’s prongs to the breaker’s terminal screw. After that, you may connect a different breaker prong to the ground screw. You can read the amount of energy flowing through your arc fault breaker via your multimeter. Either 120 or 240 volts will be the best reading. Replace your breakers well right away if your meter doesn’t register anything.
