[C320-list] Power supply for AC install

[Dean Vermeire]

We have a 16K A/C unit and two 30A shore power inlets on our boat. 
However, the previous owner used a 30A splitter cable to hook up to a 
single circuit at the dock.  It regularly tripped the circuit breaker at 
the dock when the A/C was running.  I had the marina run a 2nd circuit 
for our slip.  Problem solved.

I would strongly recommend a separate circuit for the A/C.

I have found a source for the exact same breaker as the factory installed AC breakers.  I rather not have to install a second shore power circuit to supply the power, but on the other hand I'll be installing a 20A breaker in a 30A circuit.  Obviously I should not run the water heater (about 12 A @ 120V) while the AC is on.  This is a downside I can live with.  Are there other considerations I should consider?  My question is what have others done?
