electrical current limitations

Yahoo Message Number: 95952
I've had several different explanations of the current limitation in my coach when plugged into shore power & would appreciate some clarification:

A) 50 amps per leg
B) 25 amps per leg
C) total of 2 legs not to exceed 50 amps (regardless of how much on each leg).

Which is correct?

Thanks in advance,

When plugged into shore power for 30 amp all you have of course is 30 amps. When plugged into a correctly wired 50 amp system you have each leg with 50 amps for a total of 100 amps. So when you pay a little extra at a campground you are actually getting 70 amps more than the 30 amp wiring.
Sometimes at old sites they take the 30 amp for 1 leg and and add the new 50 amp leg for only 80 amps but that is rare.

A 50 amp RV service is 50 amps at 240. It consists of L1 and L2 plus neutral and ground. It is a 12,000 watt service. Volts times amps equals watts or power. L1 and L2 are each 120 volts to neutral or 240 volts across L1 and L2. Each 120 volt leg is 50 amps or 6,000 watts.

Hope this helps
