The AMP CPC is certainly my standard connector when high currents and high
reliability are the concern.

The Type 1 pins are good for 13 amps continuous and the rating seems to be
partly related to temperature.

I say this because I've run 20 amps through a pair for hours and while
everything certainly got warm, nothing failed.

I expect, though, that if the whole (9 pin) connector was running even 15 amps
per contact, things would get very warm indeed, and hence the rating.

There IS a contact type rated for 50 amps. I considered this contact type for
my motorcycles. You see, I need to jump start either my bike or my wife's on
occasion and connecting jumpers to my battery is hard and to my wife's is
IMPOSSIBLE.

Then I saw the price of the 50 amp contacts.

So I simply paralleled up 6 Type 1 pins for +12 and 6 more for ground, and
directly wired them to the battery. I've never run into any problems, even
drawing the 50 to 100 amps needed to start my big-ole Goldwing.
