Second, buy you a 30 to 50 amp adapter and use this if your CG pedestal has a 50 amp receptacle. The 50 amp receptacle will more likely have better contacts than the 30 amp. 30 amp receptacles tend to get overloaded, causing the contacts to get hot, then weaken, causing overheating of the plug.
I wonder if he is already using a 50 amp adapter and somehow drawing more than 30 amps. One needs to be careful using a 30 amp, #10 cord and protecting it with a 50 amp breaker.
