A Go-To Fuse Block – I've Installed Several and Will Keep Coming Back to This One The Blue Sea Systems 5026 ST Blade Fuse Block is a flat-out outstanding product that earns every bit of 5 stars, and having installed several versions of it across different projects I can say with complete confidence that it is the fuse block to use. The 12-circuit layout with integrated ground and cover is thoughtfully engineered and makes for a clean, professional installation every time. The 100-amp capacity handles demanding electrical loads without any concerns, and the individual circuit fusing keeps everything properly protected and organized. The build quality is exactly what you expect from Blue Sea Systems—solid, marine-grade construction that holds up to vibration, heat, and the demands of vehicle, RV, boat, and off-grid solar applications equally well. The transparent cover protects the fuse connections from moisture and debris while still allowing a quick visual inspection of all circuits without removing anything. Labeling circuits is straightforward, wiring is clean and accessible, and the overall installation experience is as professional and reliable as the end result looks. For anyone building out a 12V electrical system on an RV, boat, truck, or solar setup, this is the fuse block I recommend without hesitation every single time. If you want to do your electrical system right, start here. Highest possible recommendation.

After having bought two of the cheaper ones on Amazon at 1/3 of the price of this, I finally decided to risk the £40 and see what it's like, intending to replace one of my existing fuse boxes. I am not disappointed. The quality of this unit shines through and I have immediately ordered another to replace the other cheap one.
