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.

No inline fuse needed. The fuse block takes care of that bit for the unit. There should be a breaker near the battery for that fuse block though.
-
What size, style breaker you think might be best. There seems to be million choices out there ......ugggg!!!!
-
Depending on how many things are connected to the fuse block. I would think a 50/60 amp breaker switch should be good. You can get something that you can break the circuit if you're worried about battery drain.
-
I wouldn’t think that you need anything that large. With three units plus the Ethernet Switch you should not have a current draw of more than 4 amps. There is sometimes an initial start-up current surge so even if you managed to turn them all on at the same time you would not be pulling over eight amps. I would look for a 10 amp breaker or just install an in-line fuse.
-
I would bet that long before a 60 amp breaker tripped you would smell a problem. I assume the cranking battery is hooked up to an onboard charger and even at that a long day with that many devices could not only draw it down too low but shorten its life at the same time.

oops, I didn't see the dedicated fuse block part. :)
