Adding 30amp receptacle to Generator ready RV..Question

Hey guys,
I have a generator ready rv and wanted to add a 30 amp receptacle. It is already wired but looks like its for 50 amp.

white - neutral
bare - ground
red - hot
black - hot

I do not have a 50 amp generator and just want to put the 30 amp receptacle in. Can I just cap the unused hot wire and let it be?

So basically only use neutral, ground & one hot.


Thanks!

    Short answer... YES.. the longer answer depends on how the generator is wired internally,

    Generators used in RV's come in one of at least 3 configurations

    Some are actually 120/240 volt generators, IF yours is like this than a volt meter will show 240 volt AC if hooked black to red If this is the case I'd put in a 50 amp outlet and use a dogbone when needed.

    Some are 120 twice, in phase. this means that black to red will read zero, but either of those to white will be 120 volts.

    Some are designed to have a seperate power line for a 2nd air conditoner.. These can be a might confusing.
