John,

When I purchased my 78 Royale rear bath the electrical setup was as follows.

1. Genset cable went to a circuit breaker located in the rear closet where
it divided into two circuits. One circuit went to the main breaker & the
second circuit went directly to the the 2nd air conditioner.

2. Shorepower cable went to the main breaker (located under twin bed on the
curb side) This panel has two main breakers,one for shore power & one for
genset. Only one of these breakers can be energized at a time.

3. After the main breaker, there are three circuits protected by individual
breakers. Two of these circuits are for the various outlets and are
protected by a GFI circuit breaker. The third circuit breaker is for the
main air conditioner and is not GFI protected.

4. Summary - Outlets are GFI protected but the air conditioners are not.
(Note - My Royale does not use a 110 volt water heater so does not have a
circuit for it)

I believe this wiring was original but do not have any Royale electrical
diagrams to verify it.

Hope this helps
