Typically this fuse block would be used as primary branch circuit protection if your switch panel does not have circuit breakers built in… OR as branch circuit protection for loads that are not switched.  Examples of un-switched loads might be electronics (chart plotter, VHF, sounder, etc) with their own on-off switch, trim tabs, 24H circuits, etc.

We also have another version of this marine grade fuse block where it’s split into two positive buses, find that here: 12 Circuit Split Block w/ Neg Bus.

What We Like About This Fuse Block:

• Having a built in negative bus saves space over an external negative bus.
• It’s got two little spare fuse holders on the inside of the case, which is pretty cool.
• Comes with 20 little stickers so you can write labels to ID each fuse.
