Technical FAQs 4

What is a ground fault circuit interrupter (GFCI)?

A Ground-Fault Circuit Interrupter (GFCI) is a safety device designed to protect people from electrical shock by monitoring the electrical current flowing through a circuit. It detects imbalances between the hot and neutral wires, which can indicate a ground fault where electricity is leaking out of the circuit.

How do I wire a 20A 120V GFCI breaker?

The same wiring configuration can be applied to a 20A, 120V circuit by using the correct wire size, an appropriately rated circuit breaker, and properly rated switches and outlets. As shown in the figure below, this includes wiring a 2-pole, 20A–120V GFCI breaker with a 20A–120V outlet (NEMA 5-20R).

How do you wire a GFCI breaker?

Similar to the wiring diagram for a 1-pole GFCI circuit breaker, the built-in white wire on the back of the two-pole GFCI must be connected to the neutral bar in the main panel. The 2-pole GFCI should be installed in the two hot slots in the main panel. This configuration allows HOT 1 and HOT 2 to provide the 240V input supply to the GFCI.
