Where can I buy a ground fault circuit interrupter (GFCI)?

What is the difference between a GFCI and a single-pole circuit breaker?

Keep in mind that the difference between single-pole and two-pole normal circuit breakers and a GFCI is that there is a built-in white wire on the backside of the GFCI, and it must be connected to the neutral busbar in the main supply, or it will not work and protect the circuit properly.

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.
