30AMP Service

2010 Greyhawk, 30AMP.
Are there any advantages or cautions to plugging into a 50AMP outlet with a 50 to 30 AMP adapter? I haven't heard anything either way but want to ask before I find a situation where I might have to or run the generator.

As your current draw will be more that 30 amp the breaker on the service outlet will trip.
So stay under it. If you have to go over the 30 amp and no service available use your generator.

No, the coach only has 30 amp service. They want to use the 50 amp outlet.

Oops!..... they can use the 50 amp (with adaptor) on 30 Amp, but are limited to 30 amp on the RV breaker.

Hello Loretta.... There are no advantages or disadvantages in using a 30AMP to 50 AMP adapter. There may be times when you will need to do this because of the well-used well-worn 30 AMP plug on the post. I carry such an adapter for just such situations. Just make sure you purchased a reputable adapter.

I often choose the 50 amp outlet even though my camper is only 30 amp simply because they are on better condition many times. They are used less often so there is less wear and tear on them

The only disadvantage is your 30 amp shore line is now protected by a 50 amp breaker. If there was a short in the cord between the main breaker in your unit and the pedestal then it is possible the cord will overheat and bad stuff could happen. It is a remote possibility but is possible non the less.

We do this ll the the time mainly because of a well worn 30A SERVICE connector on the pedestal. You can note burn and arcing marks on the 30A Service like shown in this photo.


Google image

I would not want to plug my 30A Shore Power cable into this connector. This may result in your Shore Power cable to look like this and will have to be replaced...


Google image

These are my concerns at any rate hehe...

The 50A to 30A Adapter only selects one of the 50A HOT LEGS so there is no two zones of 50A LEGS feeding your 30A Electrical setup...


Google Image

As noted above in a couple of responses about the only thing to be aware of is the 50A Circuit breaker on the pedestal is now feeding your 30A Service Breaker in your trailer. If you pull more than 30 Amps from your trailer setup it will trip your 30A trailer main breaker and not the 50A breaker on the pedestal...

I forget where this was at but I have seen at one camp ground a sign saying using the 50A to 30A Adapter Cord was not permitted.

All part my infamous PLAN Bs to use when camping trying to stay ahead of the game hehe...
