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.

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.

Always been a good brand to go with
This fuse block is an excellent addition to any electrical setup! It’s well-built, durable, and designed with high-quality materials. The easy-to-use terminal connections make wiring a breeze. I love the transparent cover that provides extra protection from dust and debris while still allowing me to quickly check the fuse status. Highly recommend it!

Easy and durable
This product is a staple in our van. I keep one for back up but have never needed it. It takes my solar generator and distributes the 12 volt power to all my lights and appliances. I have heard great reviews and am not disappointed in my own purchase. It is a good value and performs perfectly. It does not have lighting. I would only recommend this for interior and non wet environments. It does not appear to be waterproof. Easy to install and fuses are typical.

they make great products
This is the perfect fuse block that I needed for my rig. It allows me to run separate circuits, some that are triggered by the starter and some that run 24 seven I love it.

Used on 3 applications
Very solid fuze panel. I have used this now three times on Jeeps. The clear cover is thick. The black plastic of the fuze holder body is solid. Its a tough product. I find it easy to press-in and remove the fuzes. They are not waterproof by any means. The clear cover is maybe splash proof. I suggest to mark which part of the fuze block is your positive and ground. It will make it easier later on when it is installed in easy to access areas.
