Just a suggestion. We have the same problem. So when my wife uses the hair dryer or our toaster we shut off the airconditioner. This stops the main breaker from tripping. Hope this helps.

I’ve never looked that closely at a 50 AMP breaker, but I believe what others have said is true that 50 amps is just 2 legs of 120VAC, which would tell me that each leg is 25 AMP. My guess is the 30A to 50A adapter is only connecting 1 leg of the 50A to your cable. If any one leg exceeds 25A on that 50A breaker, it should pop. Add the fact that the more a breaker is popped, the easier it is to pop it, they “wear” out.

Actually I believe 50 amps is 2 legs of a 220 volt service making a total of 100 amps. I stand to be corrected as I'm not an electrician.

The 50A is 2 separate legs of 120VAC giving you 100A or 12K watts. The adapter takes ONE of the 50A legs and splits it going into the trailer so that you don't have 1/2 of the 120V outlets/appliances not working. It is VERY easy to blow a 30A breaker in a 50A trailer using an adapter if you're not watching what you are doing - they are 2 very different animals.

Nope....the 50A amp service is 50A on EACH leg, for a total of 100 amps at 120 volts. That's 12,000 watts, vs the 30 amp service which is just one leg of 120 volts, for a total of 3600 watts. So the 50 amp service will provide over three times the available amperage of what the 30A service will provide to you.

You have some serious tripping going on if you can wear out a circuit breaker

Roger that! I've seen them wear out from people using them to turn lights on and off (in the retail and resturant buisness when I was a director of construction) but that took years of daily use.

Everyone seems to be forgetting something: an electrical breaker does not give its fully rated amperage on output. Most will trip at 80% capacity, or 24A for a 30A breaker and 40A for a 50A breaker. Better recalculate those watts!

That 80% capacity is also rated for a "continuous load". A continuous load is considered to be a circuit loaded to capacity for Three or more hours.
