For 30amp Trailer, install 30 or 50amp service to pole?

Thank you.

I'm not sure. It's a pole we had put in with a large breaker box. My current 30amp outlet for my other trailer is a separate outlet my electrician/car pretender buddy put in.

I would think 120/240 but not 100%

Regardless of whether the pedestal is 50 or 30 amp, you ONLY have 30 amps max for use in your trailer via the power cord.

If you install a 50 amp pedestal, you could use a 50 amp male to two 30 amp female splitter. Plug your trailer cord into one 30 amp female end and a 30-20 amp dogbone into the other and use that to plug in an electric heater, etc., separate from the trailer system.

Outside of that, the only benefit of adding a 50 amp instead of a 30 amp is if you decide to get a new RV at some point that has 50 amp.

Doing a combo pedestal like Bobbo indicates would provide for all three of those scenarios.

I would need to know what is available. If system where install is going is 120/240 four wire, I would install 50 amp and use the adapter. If system only has 120 volts available then, 30 amp three wire.

When I installed a pedestal at my house, even though I only had a 30 amp RV, I installed a 50/30/20 pedestal and powered it with a 50amp 240v breaker. While going to the expense and trouble, I figured that if I ever decided to get a 50 amp RV, I would not need to re-do it. The extra cost was relatively small compared to a 30/20 pedestal, and was negligible compared to the cost of doing it twice. There was no extra trouble, since I merely pulled one extra wire (although I did run 6g wire instead of 10g wire).

While a 30 amp is sufficient for now, be prepared for the future. "Do it right, do it once."

Dumb, unless you plan on having a 50a trailer later on. Your 30a trailer's breaker is designed for 30.
