came with a 30 amp cord and two 15 amp breakers.
We added a number of ac outlets for convenience, actually I think we have 10 ac outlet pairs and increased the breakers from two to four. That means minimally 2-3 outlets are on each breaker. The reality is that we rarely use more than a couple of outlets at any one time.
When we're home in the summer we run our trailer on 120 VAC on a standard 3 prong 20 amp circuit. We are fully capable of running the whole trailer on a single home circuit including our power convertor, refrigerator
(we never shut it off) and even our air conditioner. In this configuration we have never tripped a house breaker.
This home configuration means that we use a 30 amp to 20 amp plug convertor. This is used more frequently than the 50 to 30 amp convertor though we do carry both we only use the latter about once a year.
As to running the coffee pot and the toaster simultaneously we plug them both into the same outlet and have never blown a breaker. Our coffee pot is only 600 watts and only draws sigbificant current for minutes while it brews. The toaster draws more current but again for only a couple of minutes.
We also have an in-closet air conditioner that draws about 5 amps.
When rewiring we carefully considered the assignments of circuits to breakers. Our goal was to assure that larger loads would typically be on circuits that are with typically low current or no current companions. For example our outside outlet is on the breaker that our electric heater is typically on.
The reality, at least in our trailer the only items that draw appriciable current, are the fridge
and the electric heater.
In addition to our 10 AC outlets we have added 4 DC outlets.
The DC outlets, at least in our trailer are generally low current, used for our Endless Breeze fan and for running low wattage DC to AC convertors for our TV and Sat receiver.
We have no GFI breakers except on the house where the trailer plugs in. It came with none and we've added none.
