Title: In Line Fuse needed?
Post by: EZM on February 23, 2013, 01:21:04 PM

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. :)
