## Overview

The Blue Sea Systems 5025 ST Blade Fuse Block is a compact, 6-circuit fuse holder designed for clean, safe wiring layouts. Rated for 100 amps and featuring a positive distribution bus with tin-plated copper components, it meets marine safety standards with an insulated cover and easy fuse access. Ideal for vibration-prone environments, it includes built-in fuse storage and supports both ring and fork terminals, making it a versatile solution for professional-grade electrical installations.

## Description

Terminal feed-through fuse block offering compact, enclosed circuit protection. Combines a busbar and fuse holder in one space-efficient unit. Designed for installations where a clean, safe wiring layout is essential. Compatible with ring and fork terminals and suitable for use in environments where vibration resistance is required.

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.
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.

## Questions & Answers

**Q: What is the total amp max for the bus?  Is it 180 amps (6*30) or can you only use a few 30 amp circuits.**
A: 100 amps per block, 30 amps per circuit. This is from the manufacturer's website.

**Q: Does this fuse block utilize a single power line in to feed the 6 circuits?**
A: Yes, a single source feeds all 6. There is also a single ground source for the 6 ground connections.

**Q: What's the difference between the one with split, and the one without?**
A: Split:It provides two isolated groups of circuits. For example if you have one group of circuits that you want to come on when the ignition switch is turned on. And a separate group of circuits that will stay on even if the ignition is off. A good example for this is if you have a clock on board you would want it to stay on. See manufacturer video: https://www.bluesea.com/resources/616/ST_Split_Bus_Fuse_Block

**Q: do I need a terminal block in conjunction with this or just wire this to my battery and run everything off of this its going in a enclosed trailer to run lights and a inverter .my winch I figure would be direct to the battery right ?**
A: You can certainly connect it directly to the battery; however that connection needs to be fused appropriately.  Also, "the winch" you referenced may be an issue since the auxiliary fuse panel is only rated for 100 amps.  If you wire directly to the battery I would ensure that you have an inline 100 amp fuse close to your battery.  I installed mine with a reset-able breaker (100 amp) between the battery and the fuse panel.
