I'm building something much like the 400W Classic from Will's book. But this question is more specific.
I'll have a dedicated circuit from the battery array's busbar to my fusebox. Fusebox is rated to 150Amps. I suppose that means something about the busbars internal to it. I'm using a less than 18" piece of 4 AWG to wire this; so, according to the chart in Will's book, this wire can carry up to 300 Amps. I'm using the fatter than necessary wire cuz I have it, and I understand bigger copper is never bad (correct me if I'm wrong; I already know it's unwieldy if your in cramped space).
My question is ... can I put a 150 Amp Circuit Breaker on this circuit? It definitley protects the much larger amperage of the wire, but am I allowing to many amps to hit the 150Amp fusebox?
