Thanks all for such fast answers,
I really appreciate the community you have here and only wish I knew enough to contribute.( I assure you that I do in those forums
where I have the requisite expertise).
For the sake of clarity..
The boat starter and and the winch are on the 24 Volt system, all else is on the 12 volt.
The manufacturer spec`d the 150 amp breaker, I questioned it as well, I guess they figure if it is going into a dead short or overloaded motor is does not much matter, but it does, so I will put a 90 amp breaker in if I can get it, if not it will have to be 100.
Welding cable..never thought of that, it makes sense....DC, high current, super flexible...why am I not so smart ? Should be available on the supply ship !
And yes..I will start the boat first, then use the winch !
Next question, what is the best way to extinguish an electrical
fire on a wood boat ?
