I always keep these three drawings in mind about powering up a RV from home...
This is a typical campground pedestal wiring diagram
This is a 50AMP TEST DIAGRAM for a RV50AMP SERVICE RECEPTACLE
This is a 30AMP TEST DIAGRAM for a RV30AMP and 15A/20A SERVICE RECEPTACLE. NOTE the 30AMP receptacle is wired the same as the 20A/15A receptacles with the only different being the 30AMP Circuit Breaker and larger wiring.
These diagrams should be very understandable for any licensed/bonded electrical service Electrician.
Like said above NEVER PLUG-IN the RV UNIT until you verify these readings with a voltmeter...
