4 Circuit Fuse Block Use Example:
This would be a great choice for a smaller boat with just a few unswitched loads. Or even a great breakout point for several, individually fused loads on a common circuit.
For example: Maybe you have four expensive underwater lights, all thrown by a single switch on your marine switch panel. Combined they need a 15A, or 20A breaker on the panel… but you want to circuit protect each one at only 3A to protect them. You can run your lead from the switch to the input of this block, then slap four 3A fuses into this thing 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.
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
