[PSUBS-MAILIST] MK-101 Connectors

[Cliff Redus via Personal_Submersibles]

Jon, this link seems to be broken at psub site.

If you look at http://www.subconn.com/power-series-list-available-types, I don't see a part number associated with a 50A version of BHB2M.  There is a 50A 4 pin model HPB4M but this has a larger body and no option for 2 pin.

 Lets assume Subconn has a Hi-Power version of BHB2M.  For the sake of argument, lets call it BHB2M*  .  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.

If ever you had the cable detached from the hull side bulkhead connector and had power to the pins it would be easy to short across these exposed pins.  In other words you want it like a house receptical.
