30 Amp off 220 circuit.

I am installing a 30 amp, with internal circuit breaker, outside box for my R.V.
There is an unused 220 cooktop circuit with nothing connected to it nearby. It has a white, red, black, and ground inside. Can I hook the sheilded 6' cable to the black,(hot), white, (return), and ground to get a single 30 amp circuit? In the main panel this circuit has a double 30 amp Pushmatic breaker. This way I don't have to replace the breaker in the main panel and I can retain the 220 circuit for future use and leave the additional hot (red) wire capped. Is this a good idea?
Thanks for any help with this. Kevin

Also, do I need the breaker in the new 30 amp box or would the double 30 amp breaker at the main panel still work?

Either way. The breaker in the main would provide the necessary protection, but if the extra panel already has a 30-amp breaker, I'd probably go ahead and use it too.

Thanks for the help.

John, Thanks for the help with this question. Since the main panel is 30+ years old I hate to have to switch the main breaker off to add things to the panel. Last time I did this to add a spa circuit I had to buy a new main 100 amp breaker at a specialty electric supply for $150.00!

Thanks again. I'll be finishing this project this afternoon, or tommorrow, and I will let you know how it works out.

Kevin
