Hot Tub GFCI Question

[mwm1752]

I know this may stretch the meaning of "outlet"

But you have seen them indoors & the OP did not specify the location. a feeder protecting both branch circuits should be compliant, a ground fault in the circuit should trip any upstream protection. Mine is indoors great for plants

You are correct and of course I have even installed an indoor hot tub-- 99% of the ones I do are outdoor so I ass u me--ddd..

I agree a feeder GFCI should protect both branch circuits, that still doesn't change any installation instruction requirements though. I also still fail to see what difference it makes if it is indoor or outdoor, both need to comply with part II of 680.

680.44 Protection
Except as otherwise provided in this section, the outlet(s) that supplies a self-contained spa or hot tub, a packaged spa or hot tub equipment assembly, or a field-assembled spa or hot tub shall be protected by a ground-fault circuit interrupter.

I understand what you are saying, but I also see 680.44 applying whether it is indoor or outdoor so nothing really changes because it is inside or outside from 680.44.

680.42 is for outdoor installations and also sends you to parts I and II. Any differences from indoor installations is in the subsections of 680.42 and 680.43, or could be mentioned in parts I and II but 680.44 is not one of those differences.

Fair nuff, 680.44 applies to both exterior and interior hot tubs. Sometimes sight and thought do not connect as some of my remarks reflect. Another good reason for me personally to participate in the forum. Thanks
