Turns out there's a discussion about this on the EVDL this week. The issue is DC arcing, and one of the old hands says:
Quote:
A AC breaker at the same voltage of the DC source, does not have the larger
contact pads and spacing as a DC breaker. The spacing is contacts spacing
is wider in a DC breaker, so when a DC breaker is activated, there will be
less arc over.
He recommends going 3x over the AC rating for DC use:

A circuit
breaker design for 3 hp load on AC is only good for 1 hp on DC. So it about
a 3 to 1 factor.

Mouse: I'll post a description of the lug making process soon, and come back and add pics later. I haven't made any new ends since last weekend. This weekend will probably be spent figuring out how to mount contactors etc.
I did sneak out and replace my fried potentiometer today though.
