I've always been taught to have a disconnect "readily accessible" to the users of the hot tub. I've also been taught that the feeders to the hot tub must be in conduit and must have an insulated ground from the panel to the disconnect. It all makes sense,

However, after boning up on my code some more, I noticed art. 680.41, last sentence, "this requirement shall not apply to single-family dwellings.

And art 680-42(C) states "that contain a copper equipment grounding conductor that is insulated OR enclosed within the outer sheath of the wiring method.....shall be permitted to be used for the connection to motor, heating and control loads..."

Would this mean for a single-family dwelling, I can use 6-3 romex, no condiut. I'm thinking now though, what type of breaker would I use. Not sure if they make a 2p-50a gfci breaker, and if they do, it is probably cheaper to put a disconnect in.

if i dont respond right away, to your response please be patient. thank you again.
 
You can use romex on the inside of a dwelling. Once you exit the dwelling it must be done with the approved methods.680.42(C)-- this allows the wiring methods of chapter 3 which accepts nm cable as an approved method.

A dp 50 GFCI is readily available even at the box stores.
 
Also I have seen hot tub disconnects with 50 a GFCI breaker included at Lowe's for $70.00 it may be cheaper that way.

I just bought one from my supplier for $125.00-- I could have kicked myself when I remembered that Lowes had them. Not sure they had GE though.
 
Last week I bought 6 rolls of #12 thhn at local supply house $68.00 per roll then was at home depot for something odd an saw #12 for $55.00 per roll , sort of upsetting at times with supply house pricing.
