Roof top ac require 50 amps?

Appreciate answers, so next question is if i buy a new portable generator what should i look for. Unfortunately if I want water from my well on my boondock property in northern michigan I need 220v.

Just make sure that the plug is 30 amp with 120 volts. Some dryer plugs run 220 volts and have a similar looking "30 amp" plug. Many people have fried their equipment plugging into that plug.

Old Bisquit above has all that you need to know.

50A 5th wheel with a 15K A/C Unit

I can operated it on:
50A power supply
30A power supply
20A power supply

ALL are 120V AC.......

Biggest issue is 'voltage' of power supply
108V and I shut down my A/C Unit cause I personally do not like to operate induction motor on less than 108V (if that low I run generator which is 30A)

Course there are limitations on each CB Amp Rating
50A.........pretty much can run everything in 5vr on 'electric'
30A.........might have to swap fridge/water heater over to propane
20A.........A/C Unit and converter. (Did that for over month one time)

The gentleman was uninformed. You can run your AC on a 30 amp power source. If you have two AC units you will want to only run one of them at a time unless you have a good power management system. I would avoid trying to plug into a 20 amp circuit, just to many "Maybe's".

My 50 amp service 5er is currently plugged into my home 120v 30 amp rv receptacle / plug on a 30 amp breaker and I can run both ac's with no problem. Its over 90 degrees outside as I write this.

Also when camping in many state parks 30 amp is the highest amp power available and I run 1 ac with no problem & the hot water heater and microwave.

I have also run 1 ac on 20 amp service with no problems in the past.

It is hard to fathom, but so many RV sales people and even worse, technicians are so ignorant about RVs and electricity.

It is possible to run ONE RV A/C on a 20 amp circuit, provided there is nothing else on the circuit and the A/C is the only thing on in the RV and the extension cord is not too long.

Well I would say that is likely incorrect. Does your 5er have an energy management system? How many AC units? What is the start-up amp draw of the AC(s)?

It's a shame that some people doing this don't have a clue. There probably won't be a problem if the batteries are charged and nothing else is running. I run my AC at home on 20 amp circuit and don't have a problem.
