Well-Made, Reliable, and Worth the Investment
I really rate Blue Sea products, and their fuse blocks are no exception. They’re solidly built, clearly labelled, and everything fits together exactly as it should — no fiddling or second-guessing. Compared to some of the unbranded or look-alike versions out there, these are in a different league. Yes, they’re a little pricier, but you’re paying for reliability and peace of mind — which is exactly what you want in an electrical setup. Definitely a worthwhile investment if you want something that just works and lasts.

Top quality marine fuse box
Blue Sea components aren't the cheapest, but their design is sound and build is top quality. This item is useful when spurring off an existing cable, as its important to correctly fuse each sub-branch and connected device. This version with internal ground bus means you can do the whole job within one unit.

Great Quality Product
This is probably the best small fuse box you will get for a boat. High quality fittings, stainless parts and useful little labels. The negative bus means wiring can be kept very neat too. It also holds spare fuses.

Fuse block
Great piece of kit. Just fitted it to my boat and it was easy to install. Very compact and provides 6 fused outlets.

A good simple fuse box
I needed to extend the existing consumer unit, this was a fast and simple solution. Partly disappointed that Blue Sea had not included the six fuses needed. It would have saved me a trip to the chandlers.
