if I have 3 GFI circuits how many neutrals do I need. Can you share a neutral with 3 GFI circuits.
A two pole gfci breaker can share a neutral. I've never seen a three pole gfci breaker.
The only way to buy those (new from a distributor anyway) if you want a really good price is to throw one in with other items on a job quote, of course you have to buy all the items on the quote as well.I found a 50A Sq D QO GFCI breaker for 429.00$ if you are interested.

If you share the neutral on the line sides there is no issue. For instance, run a full boat to a jb and then have 3 circuits come off that to 3 gfci receptacles

Full boat? I assume that means 3 ungrounded conductors (one from each phase), one grounded, one grounding?
A full boat is 3 of one kind and 2 of another.
What you described would simply be 3 of a kind.

Three hots and a neutral would be a full boat, also called a round house on some crews.I'm quite familiar with the poker definition, just never heard it applied to wiring. How *would* it apply as Dennis mentioned? 3 hots, a neutral, and a ground is the minimum needed for a 3 GFCI outlet setup from a 3ph panel isnt it?
Exactly, though the ground is incidental since it is not really part of the circuit. In NEC parlance, it's a MWBC.I'm quite familiar with the poker definition, just never heard it applied to wiring. How *would* it apply as Dennis mentioned? 3 hots, a neutral, and a ground...

In electrical, the term full boat has the meaning of all ungrounded and the corresponding neutral. So for single phase 120/240 it would be three CCCs. For three phase it would be four CCCs. And for balanced two phase, where it existed, it would be four hots and a neutral.
As mentioned, an MWBC for whatever the supply scheme was.
Be careful-- a full boat doesn't necessarily mean 3 current carrying conductor in single phase or 4 in 3 phase. The neutral may not count as a current carrying conductor
Full boat
single phase--2 hots & one neutral
3 phase-- 3 hots & one neutral
