[PSUBS-MAILIST] MK-101 Connectors

[Alan James via Personal_Submersibles]

Hi Cliff,
as I understand it the connector amp rating is 25 amps for the 2 pin unit.
That means 12.5 amps per pin, which is about 1/4 of what you want.
Cheers Alan

I think there is a big factor of safety.  You get the same issue when you look at agency's specs on how much current a 10awg wire can handle.  Having said that MK sells there lower units with 10 awg wire.  US coast guard would have 6 awg for this current.

This needs to be looked at but my guess is that this will handle it.
