Blue Sea Systems ST Blade ATO/ATC Fuse Blocks
ST Blade ATO/ATC fuse blocks consolidate branch circuits and eliminate the tangle of in-line fuses for electronics and other appliances. Their robust design makes them ideal for marine and vehicle DC electrical systems.
All buses and fuse clips are tin plated copper for corrosion resistance and optimal electrical conductivity.
All ST Blade fuse blocks utilize a specialized fuse clip that is designed to hold fuses in place in the harshest conditions.
All fasteners are stainless steel. Screws contain a captive star lock washer for a faster more secure installation. Studs utilize flange nuts for a simpler and safer installation. Fuses sold separately.
Additional Key Features Include:
Ground Bus: For DC negative connections. (5024, 5025, 5030, 5026, 5031, and 5032).
Includes Cover: Easy to open insulating cover that provides access to fuses and satisfies ABYC/ USCG requirements. (5023, 5024, 5045, 5046, 5035, 5025, 5028, 5026, 5029 and 5032).
Independent Source: Each circuit contains an individual feed wire. (5035 and 5037).
Common Source: Single feed wire supplies power to all circuits in the fuse block. (5023, 5024, 5045, 5046, 5025, 5030, 5028, 5033, 5026, 5031, 5029, 5034, and 5032).

I used 8ga wire for the Positive and Negative Pus as I was only running the cables 2 feet to the battery, and for the two components I have hooked up I'm using 16ga as that is all that's required for the amp/wire length.
If I HAD to complain about something It would be the fact that the fuse block has a 100 Amp max per block, and a 30 Amp max per circuit limitation. If you wanted to use all 12 circuits you could only use an average of 7.5amps each (technicaly just over 8 amps but the don't make 8 amp fuses) So if your purchasing this for your jeep and have a lot oh halogen lights you want to wire up or perhaps a large boat you may run into some power constraints. Granted 100 amps is still a lot of power but It's the only limiting factor I can think of.
The connections for the fuses are all solid and hold the fuses tightly. The fuse block has a nice heft to it and has Two easily accesible spare fuse holders in the cover. I found the fuses stick out far and have adequate spacing between them to easily pull them out with out a special tool or pliers. The only complaint that I could have with it is the size of the studs and nuts on it. They're good for smaller ring terminals but I used 4 gauge wire and the only ring terminals I can get locally are large enough to fit over the nut. This is easily remedied with a washer but it would have been nice to have one supplied with it anyways.
Overall I'm extremely satisfied with this fuse block and will purchase more in the future.
I wouldn't recommend using higher than 25A fused loads, as the current draw can be rather high and cause the fuse to melt inside of the receptacle, rendering that feed being useless. I had this happen to me on my offroad truck for the electric fans.
The screws and terminals are stainless steel, so no worrying about rust and corrosion. The power out connections are screw terminals, which is superior to the cheaper quick disconnect terminals of competitors products.
Only downfall is cost.
P.S. - The other fuse block shown in the picture was re-used when wiring this particular car, and was soon replaced with a Blue Sea Systems product!
It bolts straight to the positive batter terminal. You simply add your acc wires to the screws on the block ans when ready to use put your fuse in place, then ready to go..It came with a see through cover to protect everything from the weather,. When done everything looks nice and organized, no extra wire curled up in odd places. Great for lights, stereo, of any other electrical items you with to add to your vehicle.
