[PSUBS-MAILIST] MK-101 Connectors

[Jon Wallace via Personal_Submersibles]

Talked with Jennifer Stewart at MJ Stewart which is the distributor for 
SubConn in the US.  She confirmed what I wrote below.  Each pin is rated 
for 25 amps but the BHB series connector material has a max rating of 50 
amps.  Divide the connector rating by number of pins to find the total 
amps per pin.  In short, the two pin configuration is adequate for the 
MK 101's.

Also had a short conversation about custom cables.  I need someone to 
come up with a simple spec...connectors, cable length, wire gauge and I 
can get a quote from them with that info.  She said quantity will be 
important to keep the price down...ten is a good number, 15 is a better 
number (her words).
