I recently converted from a dual hot water tank setup in my house to a single tank resulting in an unused 30amp double pole breaker. I would like to use this breaker and the 10ga wire to power a TTL-30 outlet for my RV when it's in the driveway. Since the double pole is 240V through 2 conductors and I only need 120v is it acceptable to terminate the red conductor and just use the black (hot) white (neutral) and bare (ground) on the double pole breaker?

Thanks

Ground does not go through the breaker, It goes to a separate bus to which all of the safety grounds going into the box are attached. It's OK to use just one side of a DP breaker as an over load on the hot leg will cause both of them to trip. I haven't seen it done in residential, but in marine shore power systems we have both hot and neutral going through a DPDT breaker because neutral is considered to be a current carrying leg and both must be broken. Before an armchair electrician jumps on my last statement, our electrical standards are set and regulated by ABYC and the USCG and do not run in lock step with the NEC. I'm simply stating that is is OK to have one side of DPDT breaker unused or it can be used for the neutral leg.

Mr Landry, please do not bring marine electrical info in a discussion of residential or rv electrical info as it is very confusing. It sounds like you are advocating 220v on a 120v rv receptical.

Sorry, I didn't mean to confuse you. Obviously you didn't bother to read the entire explanation in context.

I read your whole post and you did not confuse me, but you could confuse others. I take it that in marine applications the neutral is run to the main lugs on the panel thus you only have 120v available. Am I wrong? Have a good day.

In marine applications, the neutral does go to a breaker because neutral is considered to be a current carrying leg. We use a DPDT for the input on 30A and for 50A a three pole breaker is used. Some of our air conditioning uses 240V. The panels we use are electrically the same as household in that 240V is available by using a DPDT breaker. So, like a household panel, we have both 115V and 230V available.
