That's a MUST I admittedly never heard of before. I was told that B. installs them as OEM... kudos.
I hope some but I (STU, MAIN SAIL, GOD..) May gel+ me in designing a decent, care-free system, as I don't trust has-dropping electricians all around any leisure dock
I attach what I sent to a German dealer of Littlefuse Inc. - USA
" Sirs, in installing the electric
system on a boat under refit
, I need your technical advice, about choosing the correct Intercept Current Fuses
, from Littlefuse, or similar.
bank: 2x200Ah LA batteries, cranking on a Volvo
TAMD 31-LA 3Lt. Diesel engine
2 house banks (services) each made of 2x140Ah Yuasa 12V batteries (total = 4 batteries)
They are charged separately by 2 chargers (230V 60A and 45A) but used as a single
bank when not under charge.
and 5300W bow-thrust and nr.3 electric
winches depend on the Engine bank.
I do realize that IC fuses
are a must to prevent shorts, and the relevant (scaring!) damages that High DC can generate. Each battery
has cold crank 815A..
I make confusion between nominal fuse Amp, and the AIC, which is rated by the thousands (up to 20,000A DC) but isn't it safer to have say 1000A on a 815A battery
which, in SERVICE
USE, is designed to deliver approx. 5-10% of rated nominal Amp? (I.e. 7-14A each).
Sorry guys, I'm just a mechanical eng. ... :-)
