I'm building an overland rig and using this example diagram:
There is a 400 Amp T-class fuse between positive battery and cut off switch. But there is also a 400 Amp T-class fuse coming off the positive bus bar on the cable headed to the Inverter/Charger.
My question is.. if any short happened on that leg between positive bus bar and Inverter/charger, wouldn't the fuse between positive terminal battery and cut off switch take care of it? All the other items on the positive bus bar are behind circuit breakers.
If the fuse between Inverter/Charger and positive bus bar is required, wouldn't it be better to place it at the output of the Inverter/Charger (power going from Charger TO battery) and not close to the positive bus bar?
Just curious if that extra $100 fuse holder and T-class fuse between Inverter/Charger and positive bus bar is really doing anything.
