Blue Sea 5191 Terminal Fuse Block 30-300AMP

Blue Sea 5191 Terminal Fuse Block 30-300AMP

Q: Does this item come with the fuse terminal included? If so, how do I specify the amperage

I just ordered three of these - they each came with a 300A fuse. I was not expecting fuses to be included, so I had ordered them separately. If this is not a shipping/packaging mistake, it would be nice if the seller gave the option to choose a fuse size. While I can use a 300A on one of the terminals, I needed smaller ones for the others. I didn't buy them weeks ago because of the relatively high price of these fuses (typically ~$15 each). They were on sale for $10, so I got them now.

Q: I have a new 100ah 12v lifepo battery. what fuse size do i need to go with this?

At solavanbuild, I use 150 amp fuses with 1/0 AWG battery cables in most of my installs.

Q: I'm thinking of running a charge/power wire of the alternator to a trailer battery. Would it be OK to use this off the charge lead on the alternator?

I would recommend an automatic Charing Relay ACR. Blue sea makes great ones. I use their Mini-ACR because my boat alternator is less than 65A. Their standard handles up to 300A. Remember regardless, you will need TWO of these fuses, one at each battery. If your alternator puts out 60A then 75A fuses, if it puts out 100A than 130-150A fuses.

Can I use this as a bus bar (without a fuse), just to extend a 5/16 battery terminal. Thank you
