im doing a hot tub/ above ground 5k gallon pool install. my question is this...

i've seen spa GFCI load centers that have the required 2 pole 50a GFCI for hot tub AND also space for two additional breakers. isn't this essentially a sub panel? what i want to do is run #6THHN in pvc from main service with a 2pole 60a to a GFCI spa load center with GFCI 2 pole 50a (hot tub) and 1 pole 20a (pool pump). Are these load centers essentially treated as sub panels by the code? and what are the requirements for disconnect in this circumstance?
 
so the load center itself counts as the disconnect? cause i think the "disconnecting means" needs to be "no more than 5 feet from inside wall of spa" but i don't wanna install this thing too close? should i run a motor rated switch in between and install it in an outdoor box as the disconnect?
 
It needs to be more than 5 feet from inside walls of tub or pool but still within sight of equipment it serves to be considered the servicing disconnecting means. If it meets these requirements for both items then it is acceptable otherwise additional disconnecting means will be required. Additional disconnect would not require integral overcurrent protection.
 
cool. i just searched other posts on this subject...and what i still have a question about is whether or not, i want to run NMC 6/3 under the house to a Jbox then splice and run through the wall and into trench in pvc to the GFCI disconnect. is that main run of nmc 6/3 considered a "feeeder" in which case i would need the EGC to be insulated (which its not in NMC) so i'd have to run pipe ALL THE WAY from panel to GFCI spa box with #6 THHN?

any advice would be greatly appreciated. thanks
 
Yes, and its worse than that -- pool feeders must be in conduit too, and only certain types of conduit, with an insulated grounding wire. Need to read 680.25. You could also consider getting a 60A GFCI breaker for the feeder to GFCI everything. Then, you won't need on for the spa or pool pump motor. Note that in 2008, pool pumps, even if hard wired, are also required to be GFCI protected.

There are debates whether the conductors of a 50A branch circuit going to a 50A disconnect with a circuit breaker is a feeder or branch circuit with supplemental over current protection. But if there are multiple breakers in that panel, then no question it is a feeder.
 
ok. i just tried to find where in the code it says that feeder ECG needed to be insulated. i'll i could find says that they are permitted to be bare. is it really code that feeder ECG need to be insualted? cause i really want to just run the NMC 6/3 under the house. it'll be WAY easier and cheaper and i don't see how it is any less of a solid install.

also i don't think that i'll install the GFCI breaker in the oanel, but use the spa gfci disconnect..only because of the price difference is pretty big and what else i have read about false tripping of the GFCI breakers.

Did you look at 680.25(B)?
