50 amp

Why in this age of technology ,why can they not make a smaller 50 amp cable instead of the un-yielding logs we have to use now?

This does not answer your question but - I would gladly have paid more for my Forester 3051S to be wired for 50AMP service. Or at least a power management system like most coaches with 50 amp service have. I get sick and tired of turning off the fridge/hot water heater/ac to run the microwave, coffee maker, induction cooktop, hair dryer, and on and on. If you have ever had 50 amp and go to 30 - believe me - you will miss the 50.

The answer to that question is yes!

Since the 50->30 adapter is only using one leg of the 50 amp service, your 30 amp surge guard will work just great. Your surge guard and your camper's main will still prevent you from pulling more than 30 amps from the available service.

I suppose if you soaked a 30 amp gauge cable in Liquid Nitrogen you could get it to carry 50 amps without melting.

Yes, the plugs are big... but they need to be to stay cool and still carry that much current. Perhaps technology will give us cooling, microwaves, etc that use less current, someday and the current-carrying hardware can be smaller.


The easiest way to describe the 2 different plugs is to compare them to the old style dryer plug and the new style. The old has 3 prongs... 120V - 30A hot... neutral... and ground. But for the old dryer, it was 2 hot prongs, and a neutral, no ground. The new has 4 prongs... 120V - 30A hot... neutral... 120V - 30A hot... and ground. The adaptor just drops a hot leg and you're still hooked up as normal with a 30A trailer. The second hot is usually just for a second A/C, fireplace, or both. That's the case for TTs and probably 5ers. Larger 5ers may share more of the load for other things on the second leg. I have no experience with motor homes, so I don't know if they're the same, but suspect they are.


Is something is wired incorrectly in the coach, with the 50A plugged in, you could end up with 240V across something designed for 120... But this will not happen to a coach using a 30A plug and a 50A adaptor... since one leg is dropped.

Because I didn't properly winterize my outside shower it sprays a small stream of cool water on my 30 amp plug at the power pole keeping it from over heating. You can tell its working from the steam that comes off the plug. ;-)

In all seriousness I am always amazed by the level of expertise present in this forum. Many thanks for your knowlegible help and for the time you spent answering my inane question as well as keeping me in the know on CURRENT events!

Guess that can be filed under a newbie question we all needed to know, but were afraid to ask! Lol
