If I'm running a dedicated fuse block, with a dedicated 10 gauge electrical line up from the cranking battery, for my electronics (3 head units and an Ethernet port) each with it's own 3 amp fuse off the block, will I need to also install a inline fuse at or near the battery?
If so how many amps should this added in-line fuse be?
What style or type is best?
Thank-you, in advance for any information.
