Two Space Heaters on 30A FW
We are going to the IL's for Thanksgiving, staying at their local city park for several days. The lows for two nights will be 26 degrees or so and I plan on using two 1500W space heaters while connect...

Maybe I missed something. Someone help me out here.
If you are using an adapter plugged into the 50A service then plugging in your 30A cord to this setup you have lost the protection of the 30A circuit breaker. In this arrangement your cord is not protected form a over current situation. I understand that the internal wiring in the camper is protected by the 30A breaker in the camper but the service cord between the camper and the adapter is NOT protected. There is a reason we have these components sized and matched to their usage. Sounds like NEC is be disregarded here. I'm not asking CAN it work I asking SHOULD it be used.
Your 30 amp cord is protected by the fact that you cannot draw more than 30 amp through your 30 amp main breaker. Electricity is not PUSHED through the cord; it is DRAWN through the cord.
Same argument could be made in a household lamp.... The 16 gauge wire supplying the power (between lamp and the wall) is way undersized for the 20 amp circuit it is plugged in to.
