Circuit Breaker on Ammeter Bypass

^^^ Good commnet IMO on the alternator link.

Correct-o-mundo on the breaker derating with heat. Was not trying to get that complicated.....! Here is the mfr's data sheet; it shows a nominal rating decrease of 10% at 150 F, and a trip level INCREASE of about 30% at 0 F. But, I expect that all thermal break devices are going to do this to some degree; I just can't say if a fusible link's rating woud decrease by 10% at 150 F, or by some other amount.
