![]() ![]() On most multimeters, this is typically the 200VAC range, but it could be lower on yours. You also place the multimeter in the lowest voltage range. The multimeter test helps you to check if the breaker performs this function, regardless of the result of the test and reset button trials.įirstly, set your multimeter dial to measure AC voltage, and this is usually represented by “V~” or “VAC” on the meter. Remember that a good GFCI entirely cuts the power supply to the electrical outlets once it has been tripped. The next step involves a multimeter and you may use it to further examine if the GFCI performs its function or not. If you don’t hear a clicking sound in any of these tests, the GFCI may be bad and you should be wary of it. You should also hear a click when you push the reset button, which indicates the GFCI is back in its active protective mode. In this first step, you hear a clicking sound when you push the test button, which means the breaker has tripped or cut off the connection. On the other hand, you use the reset button to place the GFCI back in its active protective mode after it has been tripped. You use the test button to check if the GFCI is still working, so you may determine if you can rely on the outlet or not. The test and reset buttons are usually placed between the two sockets on the GFCI outlet and are also clearly labeled. The GFCI buttons play very specific and clear roles within the electrical outlet’s circuit. To avoid fatal electrical hazards, you want to wear rubber insulated gloves and safety goggles. Our test on the GFCI involves multiple procedures where you deal with live current. We would go deeper into what each of these testing stages connotes and how you may apply solutions to issues you find. If the GFCI breaker or outlet fails any of these tests, you should fix or replace it. To diagnose a GFCI breaker, push its test and reset buttons, test the voltage supply from its outlets with a multimeter, and finally open the outlet up to check the condition of its wiring and ground connection.
