Gfcb

Will a gfcb work on a 220volt system without a neutral? In-ground pool with 220v pump and heater.

This thread had been temporarily closed. This action was taken because the nature of the question and the occupation shown in the Original Poster's profile raised a concern that this may have been an attempt by a Do It Yourself person to obtain "how-to" information.

In an exchange of Private Messages, the Original Poster has provided assurances that he is a licensed electrician or electrical contractor or is otherwise authorized to perform electrical installation work, and that the question had to do with a business issue. Therefore, the thread is being returned to the active area. I offer an apology to the OP for the inconvenience and the delay.

I'm assuming you mean a 2-pole ground-fault breaker.

Yes, it will work without a neutral connection for the load. But the pigtail from the breaker will still need to be connected to the neutral bar.

If I remember correctly, the neutral "pigtail" must be connected to a neutral supply for the GFCI to operate properly. There is no requirement for a neutral to be connected to the load side as the breaker "monitors" any wire connected.

(sorry 480, posting at same time)

I agree. Just as it will work on circuits with no ground.(2 wire circuits)

I agree with the others but am wonder what the heck a GFCB is-- ground fault circuit breaker? Never seen that used.
