Mystery Circuit Breaker

Hi All,

Hopefully somebody can tell me what the circuit breaker in my house battery bay is for. See attached wiring diagram. 2003 Dynasty.

I found it on the wiring diagram, but it doesn't say what it's for or what it connects to. This is a klixon circuit breaker that is attached to a battery pass-through post BEFORE the battery isolation switch. 

Anybody know what this is for?

Thanks,
Walter

No, this is not solar. The diagram also shows temp sensors for the inverter and solar controller over on the right. 

My red highlights covered up some detail on the diagram. The diagram shows two wires going out that area. One is the "8ga Red to Solar Controller" labeled on the diagram, with a fuse also attached to the same pass-through bolt. 

The wire and circuit breaker I'm asking about is a big 2ga cable that is not labeled on the diagram.

Ok. I think I found it! I believe it feeds the 'Domestic Hot' fuse panel in the front electrical bay

That makes sense. That wire going to the front needs protection.

Ok that’s interesting…

if you shutdown your rig - flip your main isolation switch off - does the stuff coming off that panel still run?

On my 2000 Dynasty the wire for the front Domestic hot fuse panel went through the salesman switch relay.

Yes. Mine is just like the attached wiring diagram. The front Domestic Hot panel doesn’t go through the salesman switch or battery isolation switch. It goes straight from the circuit breaker to the house battery.  

Cheers

Walter
