I thought the pigtail only draws from one side of the 50Amp plug so how do you get more than 30 amps when the autoformer kicks in?
If the camper is trying to draw 30 amps (say), the voltage is low so the autotransformer kicks in. It needs say, 2 amps to boost the voltage to 120.
Since each leg of the pedestal can deliver 50 amps, 32 is no problem.
The camper will only see 30 so it is OK.
The pedestal breaker can deliver 50 so 32 is OK.
The autotransformer will not like 32 so it will shut down.
A surge supressor will not help you as there is no surge.
