30 amp to 50 amp

I've read several existing threads and cannot find exactly what I'm looking for, so please bare with me.

The CG I've been staying at in The Keys during the end of June is slowly replacing electrical. For the past couple years the space I stay in is not replaced. My TH has 30 amp service, when it's crowded and the weather is obviously quite hot, the AC can pop the breaker or even a griddle outside. During my initial walk around, the guy told me he always use his 30-50 adaptor to plug into 50 amp service especially when the CG is busy to prevent circuit breakers popping. I always resisted this, out of my fear of electricity, but finally did it on a final day on the last trip. Scariest thing was when I was at the local hardware store purchasing the adaptor plug, there was an electrician, still em wearing his work shirt, who saw my purchase and said "oh, I wouldn't do that" after I explained my goal. Can anyone here give me a definite yay or nay on the 30-50 amp adaptor use. Pretty please, end of June is coming up quickly.

30 amp to 50 amp

I meant that I don't see where it's a good or bad idea to use this adaptor, and yes I have a surge protector I use religiously. Don't need any unwanted Amps running around giving me headaches.

30 amp to 50 amp

I posted this one time before and got backlash...
I have a Progressive Industries EMS(had on a 30amp 5er) and had a warranty issue. While talking to the tech from PI he told me to always use the 50 amp plug(with adapter) when applicable, because it was cleaner power. FWIW

I use a 30-50A adapter for my 26RR when it's at my house, and I have never had an issue using it....even when running the AC and the Microwave. I have also used it at various campgrounds, and no problems there either. Just make sure that you don't connect it under load, and you should be good.

A 50A hookup is actually 110V/50A x2, and a 30A is 110V/30A x1, so a good adapter will have the conductors that can carry that much current.

I always use my 30-50 adapter when 50A is available. Never had a problem.

Very nice, thanks y'all. I just sighed a heavy relief. S'what I had mostly heard from the few campers I had asked, but that electrician threw my confidence, 50 Amps it is.

I am no electrician... Nor am I trying to put them all down... But, considering the threads if fried stuff after having the plug "professionally" installed.. half of them cannot even wire a 50amp rv plug correctly... So I would not sweat it.

It's fine to use the 50 to 30 adapter. Your main inside your trailer is rated for 30 amps so that's all it will allow to flow. so everything inside your trailer is still protected and you said you had a surge protector so that will take care of any spikes that may come down the line.

Speaking as an electrician. The guy you meet in the store might not of understood that this is a common safe practice since our rigs have an additional breaker inside that will protect our trailer

Yes you are safe with this practice
