What is the recommended procedure for testing GFCI outlets?

The recommended procedure for testing GFCI (Ground Fault Circuit Interrupter) outlets involves utilizing the test and reset buttons on the device. This method is specifically designed for testing the functionality of GFCI outlets.

When the test button is pressed, it simulates a ground fault by interrupting the flow of electricity, which should cause the GFCI to trip, cutting off power to the outlet and indicating that it is functioning correctly. After testing, the reset button should be pressed to restore power to the outlet, confirming that the outlet can be reset properly after tripping. This straightforward and effective testing method ensures that the GFCI is working as intended, providing the necessary protection against ground faults that can lead to electric shock or fire.

Other options, such as plugging in high-wattage devices or using a multimeter for voltage readings, do not effectively test the GFCI’s tripping mechanism or ground fault protection. While visual inspections might help identify visible issues, they cannot confirm the operational integrity of the GFCI outlet itself. Therefore, relying on the built-in test features is the most comprehensive and accurate approach to ensuring that GFCI outlets are functioning properly.
