GFCI Breakers

[Big Guns]

with a 3 phase system can you share the same netural with 3 individual GFCIE breakers or do you have to run seperate neturals

If you had a MWBC you would need a 3 pole GFCI breaker to function properly.

Thanks for responding Rob

Would it work if a GFCIE device was used as apposed to a breaker

You cannot share the neutrals you must use a a 3 pole gfci breaker. Three individual devices will not work.

You can use GFIs on a MWBC. They only check for leakage on their load side, not line. Or am I wrong?

Yes, you can use gfci on a mwbc but you cannot use individual sp Gfci snd link them together. It must be a DP or 3P Gfci breaker depending on your MWBC

You can supply GFCI receptacles from a MWBC.

Good point I was thinking eric was asking about line side.

But if you do, you cannot share the neutral if there's any downstream protected circuits.

I did not say you could.

My post is accurate as written.

I was just adding to it for the enlightenment of others.

I feel lighter already.

Just curious...what does the E at the end of GFCIE stand for?

Extra letter. :roll:

I know I am. Every time I post something, my brain is a little more empty. Someday, it will be completely void of memory.

If we are talking GFCI breakers, not GFPE, does anyone make a 3 pole GFCI ?

Only at (or beyond) the load end of the MWBC, where it becomes three separate 2-wire circuits.

Equipment?
