Blue Sea Systems 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.

Overall this is a great product. It is mostly thoughtfully designed and well made. Ultimately it does what it claims: You get 12 fused circuits and 12 ground terminals. You must supply your own fuses and mounting bolts/screws which is fair.I do have some complaints about this product. First, the plastic latch for the lid doesn't work well. On the unit I received, the lid doesn't click in place firmly and doesn't stay attached firmly. The lid should have a screw to fasten it to the base so that the lid stays on firmly.The other problem is that the mounting screw holes for the base are too small. They should accomodate 3/16" bolts or screws so that people have a better chance of using mounting hardware they already have on hand.I would like to see this product built to handle a higher amperage with thicker positive and negative input terminals., however for the price of this, $27.11 in May 2025, this is a great product.

Descent price, and a quality fuse box.

I used two of these to replace the oldschool "glass tube" fuse panels on my 1991 boat. I was able to make this design fit with minimal impact to my existing wiring, so I was very pleased with that. This change solved all of my intermittent functioning lights, pumps, etc. so I would recommend the change/upgrade to anyone with similar setup.

Well made fuse block. This brand makes quality products
