Using 110 connection to 30 AMP - oops

It's 100 degrees today and I connected my 30 AMP Jayco 221 to a 110 outlet using an adaptor. I needed to do some work in the TT.
The cord was heavy duty but I used the air conditioner for an hour and when I unplugged it the end of the plug was hot and the adaptor was melting. I did this before with another TT and had no problem.

I am out of my handyman league here. Advice appreciated.

don't do it again. you are overloading everything and it could have caused a fire

call an electrician and have him install a dedicated 30 amp plug. It would only cost a couple hundred dollars

Yep, I kind of figured that much out. What I don't understand is that doing the same thing seemed to be no problem in my old TT. What is the purpose of the adaptor? To run utilities that require less power than an AC?

Can't have a 30 amp installed, it's parked in a storage facility.

We use ours for the fridge and to keep the battery charged when it is parked on the driveway.

Never run AC, as you've discovered

The adapter is called a 30amp to 15amp adapter. Look at your fuse panel in the trailer and your A/C likely says 20amps...too much

Your new camper probably has a bigger A/C unit that requires more power than the old one did..

You probably have an issue now that you will have to correct. Next time you are at the CG with your usual stuff running, go out an put your hand on the plug and the last say the next 1 1/2 ft of the cord. Is it quite warm? If so, go buy a new plug end and put it on. The one you got is toast! Choose the plug end over something with a pig tail that you splice on ie. Arcom 18203-30A @amazon

The 110V outlet should be on a 15 amp breaker. If it drew enough amps to melt the connector it should have popped the breaker instead. That's what they are there for. I'd have your panel in the house checked.

Usually just the opposite is true, the new units are more efficient and draw less amps.

As to using an adapter, with the right adapter, not he hockey puck, but a dog bone type, it should work fine as long as it is only the a/c and the converter. Did it at many Rallies years ago when we went to Fairgrounds that only had 15 or 20 amp receptacles.
