OK, First timer on this so be patient... hooking up used hotspring, manual requires 2 gfi's in spa box (a 20 and a 30 amp) The 20amp gfi appears to install like normal GFI, pigtail from gfi to neutral bus, white neutral to breaker, 2 lines feed power to spa. The 30 amp, however, is a puzzle. Manual diagram shows to lines (240v) with no white neutral to breaker. How does the GFi function in this setup?
Thanks

There is some good information here:

It should answer your question.

Heres the thing, the spa junction box has only one "white' wire, but is fed by two GFI breakers. The diagram shows one of the breakers attached to the neutralwire, and not the other. Actually, the diagram does not even show the pigtail from the second gfi. Is it possible that the two gfi's share the one neutral?

The neutral ONLY goes to the 20 amp breaker.

Thanks for the reply. One more question. Does the pigtail from the 30 amp gfi attach to the neutral bus?
