I have read other posts, but they don't seem to directly answer my question. If I missed the correct post, I apologize in advance.
I am building a new house, and am paying to have it pre-wired for a hot tub.
The builder's electrician is considering using 6AWG Romex wire for the interior wiring to an outdoor disconnect. The actual hot tub, and therefore the wiring from the disconnect to the hot tub, are not in place. They will be purchased next year. Most of the models that I'm considering are 240v/50a models. They all say that they recommend a 4 WIRE installation.
My understanding is that the Romex wire is 6/3 with an uninsulated ground. I have seen several threads that say this is not an acceptable wire, but the reason seems to be based upon the wire being used outside. This wire will all be used inside. Am I correct in assuming that this wire is unacceptable because it does not have an insulated ground, and that has an effect on the circuit breaker?
The other option, it seems, is to use THHN wire, but that has to be run in conduits (which I prefer not to have). A conduit will require many 90 degree turns, and the electrician says they'll have to use some kind of jumper box in the middle to split up the cable pulls. Does this seem correct?
So we have Romex 6/3+uninsulated ground, or THHN 4 insulated wires in a conduit, or is there another option? Is there anyone who makes a cable of 6/4 wire that would work in the interior of the house?
I am clear on all the Article 680 requirements, and this question is specifically related to the wiring inside the house.
Thanks!
