8 Circuit Fuse Block Use Example:

Our compact 8 circuit fuse block would be a great choice for a boat with just a handful of unswitched loads, and a cramped console.

It could also be used as a breakout point for several, individually fused loads on a common switch:

For example: Maybe you have 8 separate under gunnel lights, all thrown by a single switch on your marine switch panel.  Combined they need a 10A or 15A breaker on the panel… but they only draw an amp and change each, so you want to protect them with individual 2A fuses.

You can run your lead from the switch to the input, then drop in your 2A fuses into this fuse block, then out to your lights.  Now all your lights are controlled with a single switch, but this fuse block protects them individually down to their rated current.

Now if you get an issue in one light, it only blows it’s specific fuse, the remaining 7 lights stay on, and it makes it very easy to troubleshoot the issue with only 1 wire to inspect instead of 8.

What We Like About This Fuse Block:

  • Extremely compact… takes up like no space under a crowded dash
  • Single-sided load wire exit actually makes it much easier to dress your wiring in cleanly than a two sided fuse block
