Capt,
I think you may have a very good point here.  This circuit breaker is #1 important component on my boat.  It tripped during my last outing and would not reset.  Given my conversion to electric fuel pumps vs mechanical without 12 volt DC I was dead in the water.  By chance I had a thermal breaker for my Florida flats boat trolling motor aboard.  I had to remove breaker box...wire in trolling motor switch and was able to get main DC back so I could return to dock. 

My schematics are on boat and will do a visual circuit trace to find this 50 and 60 amp components.

Will report back on correct amp for main breaker.

Question- What is your amperage for your main DC circuit breaker?  Your 3600 maybe higher than my 3100 but would be a good data point.

Sorry...your 41...
