Pretty much everything I wrote is indeed correct.
A load that has the ability of consuming FIFTY amperes should not be connected to a device that is rated for thirty amperes. I have repaired TOO MANY of these gizmos.
Mex, the thing is the 30 amp park outlet is protected by the 30 amp Park Breaker....If I get Eva Gabor syndrom and try to draw say 40 amps off it..The breaker trips. That is all that happens.
The power supply, is capable of delivering easily 1,000 amps or more, At the small (24 site) park I am in the supply is good for at the minimum 1200 amps.
But the breaker on the 30 amp outlet,,, is only 30 amps.
That is the point you missed
YES: trying to draw 40 amps off a 30 amp SUPPLY will cause issues,, I did it once (Well divide by 10) Drawing like 10 amps off a supply designed for 3 amps..Had to resolder dang near everything when done (But it worked cause...Well...I designed that supply)
But the only danger running a 50 amp rig on 30 amps is
1: The click of darkness (Tripped breaker)
2: The plug will, eventually, burn up (30 amp) but then that happens with 30 amp trailers on 30 amps rigs as well. Been there. Done that.
