Questions & Answers

Is there a fuse included in this?

This package does not come with a fuse

The dimensions of the product are they accurate? According to the above dimensions, I assume it's the packaged size. It can't be eight inches long, can it?

Four fuse holders are used in fuse holder 7721. It's 92 inches long x 1 inch wide. There are 51" of width in the cover and there are 5 inches of height. The size of a 12" file folder. From the specs I wasn't able to get the height.

I have trouble finding a 250 volt fuse for my 12 volt system. I want to attach a power inverter to my truck and have trouble finding it. Is there anything you can do for me?

In my opinion, the mega fuse is the best option although I think 175 amps is more than sufficient for the majority of It was great working with BC Broncos, they were very knowledge and helped me out I bought this fuse block after talking with the guys at Premier Power Welder who were also helpful. There's a fuse box at BC Broncos, but the one there looked flimsy and wasn't waterproof, though you can buy the fuses there if you need them. My opinion is that this model of fuse block is the best there is on the market.

The cover for this fuze is great

5/5

The setup I used consisted of this and a dual battery unit. Fuse placement should be as close as possible to the second battery, but since I had a fuze under the truck, I needed something sealed to prevent corrosion in addition to also protecting me from explosive atmospheres. There's nothing like living in a sweet home. This could create a short in a -) environment. The silicone I put in mine before mounting worked well.

The materials used in this product are long-lasting

5/5

Compared to most other fuse blocks, the ones I get from Blue Sea hold up better. Although it has been inside the engine compartment for years, Texas summer heat doesn't cause the plastic to get crackly.

This is an awesome product! It is of very high quality! I loved how it worked when I was wiring up my dual batteries on my Toyota 4runner! I'm so glad I bought it! This product definitely deserves a recommendation, and I would certainly recommend it to my friends!.

The product is of high quality

5/5

This is a great product. I find the straps to be a very nice However, you can bend them to make them fit under the cap if necessary. My only negative is the 1/0 wires are a bit large to approach under the cap, but this can be fixed.

This is just what I was looking for

5/5

A couple of other brands were junk, but I gave this one a shot. I was very pleased with this product. It is very heavy duty and I was not disappointed.

These are the cables I used to run extra batteries on my

5/5

A high amp alternator replaced my OEM alternator last year, so I used this to run additional battery cables on my truck. In addition to the airstream I am working on, I also intend to install a solar panel-powered battery charging As the system continues to come together, I am sure to order more Blue Sea electrical parts.
