50 amp

You can't make a single 15-20-30 amp source to be able to handle a full 50 amp capacity.

You can get adapters to plug your rig into a those lower amp sources, but you will be limited to the amp rating of the source if that's what you are asking.

Good luck!

Your original question is unclear, as others have said. If indeed you are trying to get 50 amp service off of shore power poles that have only a conventional 15-20 amp household plug and a single 30 amp plug you might consider one of these:

I have gotten an earlier version of this to work, but it seems to work best using two power poles if you have a vacant site near you, using a 30 amp extension cord to the other shore power pole. For those of you who might think I was "stealing" power, I was on a daily rate which included all electrical consumption. I have also tried this on a single shore power pole using a 30 amp female to 15 amp male adapter. It didn't work as well and tended to pop breakers.

It is certainly an adaptation and it's better to just have a 50 amp source.

Yes amazon has them

Well no it isn't amps and volts are 2 different things. You might do a google search on the subject.
