110 hookup only ???

Agreed, and if you actually read the entire thread, you would see that I DID NOT bring up the 240V topic. I was correcting some misinformation that had been posted by others who did. Go back and read. To jump in the middle of a topic and comment without knowing what had been said previously is rude.

Of course you have! Just can't run anything (or much of anything) else.

I have run an AC on 20 amp.

Bought an adapter today. Goes from 50 amp to 30 amp, it's just a short adapter, no dog bone, it cost about $10. I have an adapter to go from the 30amp to 110 20 amp service. I shouldn't need AC's where I'm headed, and probably will only use the TV and lights, will turn everything else off or switch to propane where I can. Thanks for all the feedback.

you are golden! Let all the rest of this discussion slide on by. As you stated no AC and keep total draw under control and you will be fine.

You go find an RV actually using 240 V and let's see if it costs anywhere close to $1,000,000.

If it is not a dog bone (and initially, even it it is a dog bone) I would check it for heat. Sounds like a "hockey puck" style. IMO, placing these connections in a "hockey puck" is cheap but may increase heat inside the adapter. Also as noted above, if this 20amp line has other outlets, unplug or turn off everything you can. If the freezer in the garage is on the line and the compressor starts, you may over load the CB. I still recommend a PI EMS or a Kill-A-Watt.

When I kept my RV in my shop, I had it plugged into a 20 amp plug that I had installed just for it. So nothing else was on that circuit. I could run everything electric just fine, except the A/C's. Now I never tried to run a coffee maker and a hair dryer and all three TV's at the same time, but it ran everything I needed to run just fine. And I could start and run one A/C unit and the TV at the same time, but never really tried loading anything else on.

50 amp breakers are dual voltage, 120-240-120 Depending on which wires you draw power off of..

The TT 30 outlet has, clearly printed upon it "MAX 125 Volts" And is not to be used for 240 volt service.. Still many do wire them that way. and live to regret it. Because they are 120 volt.

15 and 15/20 and 20 amp outlets are,, as you would expect, normally 120 volt (Though I do know of one that was or may well still be an exception).

But yes, There are many threads around here about folks who had an electrican install a TT-30.... Wrong

Even one from a Rver do did it himself

I did mine right.

Yes, 240 V can be measured at the breaker box but is not used in that manner.

And just to clarify this, yes, there are some RVs that have 240VAC appliances in them, namely the "all electric" rigs.

Just to clarify, it's all 110/120V service. The 50/30/20 amp rating is simply how many amps are available for use of your devices. 15/20 amp service is a standard household plug, 30 amp is the next step connecting all devices to a total of 30 amps and 50 amp service provides 2 separate 50 amp legs for a total of 100 amps available for use but more than 50 amps on either leg will trip the combined breaker.
220/240 V service is not used but rather 2 separate 120 V legs. Yes, 240 V can be measured at the breaker box but is not used in that manner.
