This is a typical wiring configuration for a RV 50 Service. As you can see it is two 50AMP HOT legs. This is called a 50A service butin reality it is a 100AMPS service...

You can confirm this by using this chart and a AC VOLTMETER...

If you use it any other way in a RV setup you will get fireworks...
The two 50A service connections normall feed two zones inthe RV 50A Setup and on some of the high end trailer you can get a 240V circuit to feed a Washer and Dryer combo setup...
The two 50A 120VAC zones is pictured here in this typical pictorial..

If you use a AC VOLTMETER and read across the RED and BLACK ZONES in this pictorial you will read 240VAC potential. Since this is not tapped to be used in most of the 50A Trailers it is no issue. However if you make changes etc you can get into some very hot stuff...
