5026 ST Blade Fuse Block 12 Circuit with Ground and Cover, 100 Amps

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.

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.

rewired a cheap terminal strip with fuses with this unit, great quality, nice looking. very easy to use. this really helped clean up a wiring mess on a sanger ski boat, i would not hesitate to use one again

I bought the Blue Sea Systems ST Blade Fuse Block (6 Circuits, with Cover, no Negative Bus Bar) to expand the 12V coach power network in my RV. Compared to similar 6-circuit fuse blocks from other brands, this one is a bit larger and definitely more expensive—but in my opinion, it’s worth it. The build quality is excellent. It feels solid and well-made, unlike some of the flimsier alternatives I’ve used before. Installation was straightforward, and it works exactly as advertised. Given how critical a fuse block is in any power distribution setup, I think spending a little more for something this robust and reliable is a smart move.

Works great! Blue Sea always makes quality products. These one sided fuse blocks are better for mounting in smaller spaces where you cant run wires to both sides. Unfortunately the cover in mine will NOT stay on. I understand the covers are not super important, but I like to have my positive leads with some sort of cover.

Exceptional service! Very satisfied with product.

Does what it should, can run all my items with the proper fuses.

Chose this to tidy up my engine compartment. I use it to connect my PV system to the battery and to run power to my Hella horns, under hood lighting and, in the future, power an Onboard Air System. It's a simple component, easy to install and high quality. Been installed going on 4 months now and I see no signs that this is going to be anything less than awesome. Every Blue Sea Systems purchase I've made has been awesome.
