[PSUBS-MAILIST] SubConn BH4F and IL4M Connectors

Remember, on boats, and in submersibles, you want to have an ungrounded electrical system (no continuity between battery negative and hull / equipment chassis protective earth), and you will want main fuses / breakers on both the positive and the negative leads coming from the battery. Ideally, you want these protective devices as close to the battery bank(s) as possible, but accessable so that you can replace fuses or reset the breakers if you happened to cause the short or it is otherwise repairable before going live again.

She said a competitor went out of business which has created a huge draw on their manufacturing capacity.  She assured me that our small orders are not preempted by orders for 20,000 units.  She did say most items are on a 12-16 week back order.

Only problem is, I really do not want to be responsible for shipping.  Someone we know and trust would have to volunteer to hold the stock and ship items when our members order them.
