Add a little to that for good measure and you can use a 50A fuse normally OR a 40A fuse if you want to be extra safe.
I hope that was simple.  |
One small confusion in this methd:-
Do we need to consider voltage at 12v or 13.8v or 14.4 v
should one take some headroom while arriving the above figure for the sake of saftey
