Very hot power cord with A/C on??

Aside from checking out the pedestal, have (here is the C.Y.A. disclaimer)a certified electrician check your electric panel in the RV. My cousin kept blowing his breaker and it turned out there was a loose wire connection to the AC breaker.

Also I have been in two State Parks where the pedestal breaker kept blowing and the breaker was hot. The park maintenance man had to come a replace the breaker.
