This is a well designed fuse block with quality materials that fit my needs for compact installation on my off-road vehicle. The Blue Sea Systems electrical components that I have used, withstand the rigors of temperature/ moisture/ vibration that I expose them to in my off-road vehicles over the years.

Used mine for multiple power source for the rear of my tractor. Just know that it is only a positive buss bar and the ground must be used from another source for the light or switch from the battery or frame. This is what I wanted because I would have less wiring going to this box (only positives) and use a grounded OE factory bolt for a ground. No problems when washing the tractor, but I would not applied a direct high pressure spray. I would trust it in a heavy rain though. Would buy again if I need one!

Bought this to build a 12V electrical system for my Boston Whaler.Easy to install, nicely made and compact. Waterproof seals look to be good quality.

Used this in a vehicle and couldn’t be happier. Very clean way to install some extra 12v stuff. The screws that hold the front on are retained in the front face when you unscrew them to get inside- so no chance of dropping/losing the screws. Very well designed! I will use only Blue Sea from now on.
