Nice connector

It works exactly as it should. I am now able to connect different devices to the 30A of power I have coming off my lithium batteries to the 48V to 12V transformer. I like that I will be able to see visually of the fuse is blown without having to look at the element of the fuse. I also like the cover with labels so I know what is connected to what. It made my electrical installation much cleaner. I believe that it will hold up, and the connectors were very easy to screw in. I will update if anything changes.

Solid fuse box

Nice product and price used this in my car to run a mini pc in my dash that requires 120 watts minimum can pull 180+ if i put it on performance mode and i have the wires and fuse panel stay cool to the touch i did go overboard and ran 1/0 power wire to the battery bank in my trunk so it won't kill my starting batter "there's a isolator as well" with it being rated for 30 amps a per fusible output. 180 amps total you can easily pull 2,592 watts through this thing as long is that amp rating is based on 14.4v worse case x 12v = 2160 watts either way this thing is overkill , sadly the provided cover will not fit with the 1/0 wire running to it.

Reliable and Convenient for Power Distribution

I've incorporated the 12V fuse block into my custom power bank to provide a 12V source from my 24V system, and it works great. The fuse block's design is user-friendly, making the installation process straightforward. The LED warning indicators are a fantastic feature, offering a quick visual check for any issues with the circuits.One aspect I particularly appreciate is the waterproof and damp proof cover. It adds an extra layer of protection, ensuring that the fuse block remains functional even in less than ideal conditions. The six circuits with a negative bus offer ample flexibility for various connections, making it a versatile addition to my setup. The only minor drawback I've noticed is that the cover can be a bit tricky to snap on and off, but it's a small inconvenience considering the overall performance and protection it provides.This 12 Volt fuse block is a reliable and efficient solution for power distribution in my custom power bank. It delivers excellent performance and peace of mind with its sturdy construction and helpful LED indicators. If you need a dependable fuse block for your car, marine, RV, or truck, this one is definitely worth considering.

Great build quality but limited information

I bought this despite Amazon telling us it is a frequently returned item. I liked the design, and wanted to know more but could not find enough info in the description. Here is how this thing works.You provide a continuous Bat+ feed, and you CAN provide a switched connection. The switched post is common to every relay, the left side of those green screw connectors is hot from the ACC post. Each green screw post is a pair, the one on the right when provided 12v + will switch the relay, regardless of the use of the ACC post. IOW if you don't use the ACC post you can still active each relay.Most cars have switches for say, headlights, that switch the 12v + feed, so if that is how you plan to use it then you can do so and this product needs only the switched wire to work, then you connect the high amp wire to the appropriate fuse and you're done. If you have an accessory you want to switch on with the ignition, then use the ACC post from the ignition, it feeds a post that you can just jump to the right side screw-in terminal and the accessory will come on with the ignition using a relay (connect the accessory to the appropriate fuse). You can do both, activate a relay with your accessory's switch for some relays, and active accessories with the key.The LED indicating if the fuse is good works regardless of how the ACC post is used.What you cannot do is something that I do on my classic Citroën, and that is to provide ground to the relay solenoid separate from all other relays. I do this because the starter solenoid is on a relay (starter solenoids draw as much as 30 amps, so I need to keep that away from my 50+ y/o ignition switch). The relay works fine, but I have it triggered by a switch on the console, and I want to disable the switch when the engine is running. So I get ground to the relay via the alternator voltage regulator. When the engine isn't turning the VR provides ground, but as soon as it starts producing power that line goes positive (that's how it turns off the battery light). Thus the relay can't work and the starter is safe from unintentional activation.Okay, that's not a huge deal, but what is for me that the total lack of documentation about 1. how this thing works (I had to hook it up and try things to ensure I understood how it works), 2. zero documentation on the load max for each relay. I suspect it's 20 amps, but it's not documented. There are six relays on the board, 4 pin relays only (I have one setup that could use a 5 pin but not actually needed with this product). These are micro relays, similar to what I already use in the car. But they are enclosed in a housing that is not ventilated. The description states this thing can handle 80 amps, but 80/6 would be justs 13.3 amps per relay, so perhaps they are rated to 15 amps max? Without clear documentation it is a guessing game, and I dislike guessing with electrical equipment.The cover comes off easily if you can press in the releases. That's not easy from over the cover, but if the thing is in my hand and I press the releases from the bottom it comes off easily. So this needs a redesign to turn the releases around.It came with a lot of fuses BTW, so I'd think you could put it in place with the fuses provided. The build quality is quite good, it's not light for what it is, I would think it will last a long time. I like the fuse LED indicators, but that's not unique to this product. It's fairly compact. I can't say that I'm a fan of the screw-in terminals for the switching wires. If there was a cable retaining strap for them I'd be happier, but I'm concerned that the wire can come out and short to ground when you activate the switch, which is not something you want to happen. Without a cable retention mechanism I'd prefer a screw I can either wrap the wire around, or use a small ring terminal on the wire. I have not determined if I'll use this product on my car.Edit: I decided to use this in my car and it’s working as expected. The relays are rated at 20 amps (I took it apart to find this out). Build quality is quite good. I don’t find the cover difficult to remove now that it’s mounted. It replaced 4 relays and a six fuse block, the wiring is far cleaner than before since I don’t need independent ground and Bat + wires to each relay. The fuse labels are marine centric, I used my Brother label maker to make new labels. I did not tin the trigger wires, the clamp is a nice long flat bar and I think that gets a better clamp than if I had a soldered end, and solder can cause work hardening failure where the solder ends. I’d still like to have a strain relief, I think one could be made to clamp down using the Bat + posts to hold it, so I’ll,be looking at making one from plastic.

Good quality works great

This was very easy to hook up and performs great. I'm currently running 2 circuits and it's working out good.

EXCELLENT PRODUCT, WORKS AS DESIGNED

Works exactly as designed and well made. Do not make this more complicated than it is. When wired correctly this relay/fuse block provides keyed power to six separate relays (the terminals on each side next to the corresponding fuse) through the use of six user provided switches (wired through the green terminal blocks along the bottom). The ground terminal and ground busses are electrically common to each other. To provide unswitched power to a relay simply jumper the corresponding green terminal block and your relays will always be hot!Edit to add: There are less expensive versions of this exact (nearly) product.

Time to update that wiring mess, isn't it?

I bought this to remove the original glass fuse block in my 1963 Chrysler Newport. It arrived quickly, easily worth the low price. The terminals are nice, it feels hefty in your hand, and it's the kind of polymer that wont shatter if you press on it too hard. The fasteners are nice as well. I opened it up to see what the internals look like and it looks great honestly. I'm not worried about it failing or catching on fire. It's a good size, fits under my dash easily, and looks really clean too.

Good Choice for the price point.

Worked fine, but I returned it for a 8 button Bluetooth gang switch, it fit my project needs better.
