I'm working on an old system that uses 240V control wiring. Since the wiring runs through several user panels, I would like to protect it with a GFCI. But I have not been able to find a 240V GFCI.
There are no 120V loads connected, so the current flowing in the phase conductors should be equal until a ground fault occurs. Seems there should be such a device--same as a 120V phase/neutral GFCI, except that it should open both phase legs when a fault is detected.
Any help on how to find this (or why it doesn't exist) will be appreciated!
