## Overview

The Blue Sea Systems 5026 ST Blade Fuse Block is a compact, 12-circuit fuse block rated for 100 amps, featuring a durable polycarbonate cover that meets ABYC/USCG insulation standards. It consolidates branch circuits with a positive distribution bus and tin-plated copper components for reliable conductivity. Designed for versatile applications, including dual voltage setups, it offers easy fuse access, built-in spare fuse storage, and a secure push-button latch, making it an essential upgrade for professional-grade electrical protection and organization.

## Description

Organize and protect circuits with a covered fuse block. Fuse Blocks are an effective method of protection to prevent damage to wiring and possible fire in the event of an over-loaded or short circuit. This Blue Sea Systems space-saving fuse block can provide protection for new installations or when the panel has run out of breakers. Often used for electronic installations, this fuse block can be fed by one breaker from the distribution panel and supply power to 12 additional circuits. Compact size allows it to be installed in tight spaces close to the loads they protect. Accept ATO/ATC fuses that provide protection from 1 amp to 40 amps.

Review: Great Split Bus Blade Fuse Block - First off, Blue Sea Systems products seem very well made and I am pleased with the products that I have purchased. I purchased this product for a project I am currently working on. I have a vehicle with a 6V electrical system. I wanted 12V to power other decvices and I wanted to be able to fuse both the 6V and 12V circuits. This product has a split buss that allows for 6 circuits on each of the 2 busses which allowed my to connect two different voltages one on each bus. I used a 6v to 12V boost converter then attached the 12V to one bus and the original 6V to the other. Both busses share common ground connections which I found very convenient. I also like the clear plastic cover so you can see the blade fuses. And with easeyID fuses, with leds that illuminate when a fuse is blown, it is quick and easy to identify which fuse needs replacing. Over all I am totally pleased with the quality and cost of this product. I would, and have already purchased more than one of these devices and would recommend it to others.
Review: Well made, versatile - I used this to safely, cleanly add more circuits to an older vehicle. The split-circuit design was exactly what I needed, because I needed some circuits on battery power, like the radio clock, and some circuits on ignition only, like gauges. It was probably twice as big as I needed, which caused some mounting challenges, but it was helpful to have terminals accessible from both sides. The grounding block also wasn't strictly needed in a car, because you can ground anything to the vehicle body, but it did simply wiring. I found the block to be very sturdy and well-made, and the cover adds another layer of protection. Finally, the built-in fuse puller and spare fuse holder is a good "just in case" feature.

## Questions & Answers

**Q: What size ring connector is needed to attach wire to terminals?**
A: They are #8 as described in the description. Hard to find #8 rings in heat shrink connectors. #10 worked just fine for the terms and it seems all manufacturers sell this size.

**Q: Can I run +/- from batt to 100 amp breaker then +/- to fuse box so I can kill power to fuse box?**
A: Yes you can.  The fuse box will be powered off breaker.  I used a toggle switch panel instead of a main breaker.

**Q: Product page says this can handle 100 amps per block, does that mean 100 amps on the left 6, and another 100 on the right?**
A: No, it means 100a peak draw for the entire block...30a peak per circuit.  The main positive in should be fused at 125 per the specs from BlueSea.

**Q: Does this block come with a positive and a negative bus? I don't want to have to daisy chain the positive lead to each lead on the panel...**
A: Yes, it does indeed come with both a positive (fused) bus and a negative bus. Very nice unit, as with all Blue Sea products. I would and have bought again after purchasing mine.
