From the manufacturer
ST-Blade Fuse Blocks
Consolidates branch circuits and in-line fuses
The ST Blade Fuse Block was designed with fastener terminals to comply with ABYC Recommended Practices, and are built with tin-plated copper components for improved conductivity and lower operating temperatures. An optional cover protects the conductive surfaces from accidental shorting, labels each circuit, and stores spare fuses.
The ST Blade Fuse Block is ideal for use as a sub-panel in the DC distribution system. This solves the problem of using large and expensive circuit breaker panels as circuit protection for electronics and other branch circuits. With most circuit breaker panels a circuit breaker and an inline fuse are used for to protect electronic devices. By instead utilizing Blue Sea Systems ST Blade Fuse Block as a sub-panel, fuses more appropriate for electronics can be used, removing the need for inline fuses while only utilizing one position on the panel. This reduces the size of the panel needed and lowers the overall system cost.
- Independent and/or Common Source fuse block
- Fastener terminals for securing wires accept terminal rings
- One-piece stainless flange nuts ensure safe and secure connections
- Clear insulating cover with label recess satisfies ABYC/USCG insulation requirements
- Accepts ATO and ATC fast acting blade fuses (sold separately)
- Some models ignition protected or ingress protected

Not only is this very simple for the purpose, but being made for marine applications, it can take weather and moisture without batting an eye.
Definitely recommend, it doesn't get more straightforward and useful than this!
This block is the best size for the systems that I have installed. Nice quality.
Pretty Simple set up. If you have your accessories all going to your battery:
1. Locate the positive and negative wire to each accessory
2. If you need to, splice (with butt connectors) the wires so that they can reach the fuse block with some length to allow you to work. In this stage, a little more length than you need is far better than a little too short, or even "exactly" the right length. You can shorten it later if you need to.
3. Locate the main positive and main negative that it attached to the battery you are using. Connect the positive wire from the battery to the positive post of the fuse block, and the negative to the negative post.
4. I attached small ring connectors to the negative wires of the accessories (bilge, aerator, nav lights, etc.) and attached them ANYWHERE on the negative positions. You don't need to worry about "where" the negative wires are connected, as long as they are secure on the negative posts and as neat as you want them to be.
5. The fuse side is numbered. With the same size small ring connectors, attach the positive lead from your accessory to the number on the fuse panel you want.
6. You can either attach another ring connector on top of the one you just installed onto another wire, then to wire that new wire to your switch. Another way is to connect your positive lead and a separate pigtail into the ring connector on the fuse block, then run the pig tail to the switch.
It may take a little tinkering, but the result is FAR WORTH the effort. I would also strongly recommend the Blue Sea Easy ID Fuses. If you blow a fuse, it has a small LED that lights up letting you know that you lost that fuse.
