I am wiring a 240 V. 2 pole switch from the main house breaker then out to a hot tub. I am using 6 , 3 Romex with a ground. There is a white wire along with the two hots Red and Black. This should be the nuetral (if I were running 110v.) but I am running the full 240. what should I do with this wire? Should I connect it spliced to the black? Also does it matter where I connect the hot wires to on the main house breaker.... Is it okay to connect to "MAIN"?

I appreciate the advise, that is true I do not have the experience on this matter. I will go ahead and use professional help for the connections. I want this to be done right. Thank you very much for the advice.

I've been studying electrical off and on for 30+ years and sometimes I need help. The experts haven't even got the NEC figured out, they keep changing it (100's of changes) every three years. Wise decision Eric, a hot tub to help soothe this winter sounds good, maybe next year for me, enjoy it.

Hi Eric, Man have you made my day! Thank you very much for reconsidering!! Now what you might do is to ask too watch so that you can learn. Most people are very willing to "a little" teaching. Some will thumb there nose at you, just hope you don't draw one of those types. Enjoy the new tub!

Eric; I would strongly advise you to leave this job to a professional, but I will try to advise you anyway. The 6-3 romex should be big enough. The white wire is still the neutral on a 240V circuit. It is connected to the neutral lug on the hot tub (it should be marked), and the neutral buss in your breaker panel (the one with all of the white wires going to it). If there is no neutral lug on the hot tub cap it off with a wire nut. The bare ground wire should be connected to the ground lug on the hot tub (also should be marked), and to the neutral buss in the breaker panel (unless there is a separate ground buss with bare wires going to it). The red and black wires are connected to the hot lugs (marked) on the hot tub. The red and black wires should be connected to a separate 2 pole breaker in the breaker panel NOT THE MAIN!
The 2 pole breaker should be the size called for by the instructions or rating plate on the hot tub and should be a ground fault current interrupter type unless the hot tub has one built in. If you have any questions or doubts get help. Water and electricity are a deadly combination.

You will definitely need the white neutral wire properly connected. Part of the timing mechanism will run on 120 volts.

Hi Gene, There is not enough info given to determine wire size as no length was given!!

Romex of any wire size can NOT be ran in any type of conduit so therfor the romex can not be used in this installation.

You stated " If there is no neutral lug on the hot tub cap it off with a wire nut." This is a totally false statement. All euipment that involves water safety has to be a four wire system at 230v!!!

As I told Eric, Stop what your doing!! I would rather you be mad at me than be dead!!!!!

Hi T_bone:

You missed the fact that I didn't tell him that he needed to get a permit to do the job! I meant no harm and you correctly pointed out my errors (talk about an ego killer). I will be more careful next time. Gene.

Hi Gene, Ya but you still have your ego and thats what I wanted to here!!! A "live" ego! I have found it's pretty tuff to think of all the ends and outs on this type of posting no matter how much experience a person has. It would be a book by the time someone could post all the correct answers for this type of installation.
