[PSUBS-MAILIST] MK-101 Connectors

Tue Jul 29 19:46:10 EDT 2014

David,
I'm a bit late here but I think we have now confirmed that it's 
50 amps combined so 12.5 per pin on the 4 pin. I haven't checked if G.L. require some sort of
safety margin. ie if the motor draws x amount of amps max, does the wiring system
have to be rated for a certain % above this.
If I follow you right, the 10 gauge Bh leads go inside the hull. Maybe it's to do with the 
insulation around the inline cable causing a heat build up. Just guessing.
Alan

Alan, What about using their 4 pin which is rated at 50amps and gang a pair of the wires and either side of the connector. The interesting thing is that the mk101 connector  thruster to controller is a 1/4" flat blade connector tied to the 8 ga wires with crimp connector.  Yet the wet connector uses 8ga on the 60cm inline cable and 10ga on the 30cm Bh leads.

Alan, 
>I've used both. A bulkhead connector and cable with the mateable plug on the tag end for the thru-hull penetrator, then a wet mateable fitting on the thruster itself. It makes changing a thruster very simple and keeps the clutter down, and might be a little cheaper when bought as a set.

>>>Talked to Subconn this morning.  The ratings are per unit, not pin. They have a high power BHB2M rated for 50 amps (25 per pin) in brass, aluminum, titanium, and stainless.  Pricing for PSUBS members on 50 amp brass is below $90, 50 amp stainless is below $100.
