[PSUBS-MAILIST] MK-101 Connectors

[Alan James via Personal_Submersibles]

David & Cliff
was thinking that if we used the 4 pin high power connector,

then the 2 spare pins could have a thermister on them measuring the motor temperature 
as you were intending to do David.
The HPBH4M "male" fitting on the motor would mean you would have as Cliff suggested, the safety feature
in that if the male & female came apart the live end would be female & wouldn't short on anything
(apart from water).
I am wondering if there is any off the shelf adapter we could use to screw this straight on to the motor wiring outlet.
Also is it feasable to attach bayonets or whatever to the pigtails (does it have pigtails) to fit them directly to the motor electrics.
Can this be done while the motor is apart & then be put back together?
Any thoughts?
Cliff, are you intending to use the saltwater motor controller?

Cliff, see my previous note to Alan.  Forget the subconn site, go
      through the Macartney site at
http://macartney.com/systems/infrastructure/subconn%C2%AE

SubConn does have a true 50amp per pin connector but it has four
      pins with a max connector rating of 200 amps, model HPBH4.  They
      don't show a two pin model but maybe we should ask if they can
      produce it for us.

And for the classification discussion, they make a one pin monster
      power connector rated for 250 amps.

If I understand what the Subconn rep said, the BHB2M* connector overall rating is 50A so if we connect to a MK-101 lower unit, and we run the motor at max load, then we would see 46 A in teach wire / pin.  For non commercial personal applications I can live with this as they have a big factor of safety but for those that are trying to get their boat classed, this is not going to work as classing agencies like ABS and Lloyds specify that parts like these have to operate within vendor specifications.  They would need a connector rating of 100A, i.e., 50A per pin if I am understanding this.
