Andy, Could you provide: conductor normal voltage level, normal amperage level, and what type fuse - fast-blo/slo-blo, 32V/250V, amperage?

I want to feel confident that, if a short occurs in the system, the conductor will not degrade before the fuse has a chance to do it's thing. So, this is not really a derating question as much as one of short term overload. Thank You, Andy Pedersen Harris Corp. [log in to unmask]
