Blue Sea Systems 2300 150 Amp Common BusBar with 10 screws and a cover

Solid copper, tin plated to resist corrosion. Very robust metal construction, not flimsy in any way, shape or form. Plastic cover fits securely on end posts to cover terminals from damage. This is a ground bus bar. Do not confuse with a positive bus bar, although in the correct installation, it could serve as a positive distribution terminal. All screw terminals on this, which allows the most secure installation using crimp or soldered on ring wire terminals. All very professional, just like my 12 volt electric installations. This is intended for marine use, and it shows. I am using this item as a negative bus bar in my truck under the hood, where I now have a large number of ring terminal ground wires bolted to the radiator cross member support. I will then attach a 4 or 8 gauge wire to one end post, and on the other post will be another of the same gauge wire going to the frame, and from there to the engine block. I like having solid ground connections The attachments to frame and engine block will be sprayed with electrical control cleaner or tuner cleaner, to maintain a good, corrosion free ground connection.

I recently used 2 of these as I worked on installing a custom stereo system in my pontoon boat. The whole system has been designed to run off one dedicated deep cycle battery.One bar was used for as a 12V source, and the other as ground. I used Anchor brand 8 gauge wire to hook from each of these direct to the battery, and used a variety of wire sizes (10 AWG, 12 AWG, and 16 AWG) to supply power to a Kenwood marine head unit, JBL 4 channel marine amp, and JBL 200W 10" sub. It was easy to keep all the wiring neat and tidy (I'm a perfectionist), so I was happy about that.after I assembled everything, with marine grade wire, crimp on connectors, and solder all around, the resistance measured through 9 feet of 8 AWG wire, the bus bar, and the longest piece of wire I had connected to the bar was 0.1 Ohms or less.Construction seems very sturdyThe covers are a nice touch, although there aren't too much more than a deterrent for rouge wires to accidentally touch the wrong bus bar - I had no clearance issues with 8 AWG wire (using ring terminals)I will post a picture of my configuration shortly.Buy with confidence!I will follow up at some point to comment on how well this product stands up to extended exposure to a salt water environment.

Very high quality, perfect stud size and looks great! Has stood up over years of being in a salt water boat! Highly recommend !

I installed new electronics in our boat and wanted them to be powered by dedicated switches. I used two bus bars, one for + and one for - to supply the switches. Worked out beautifully.

Anything blue sea systems makes is usually great quality. I love using their products for wiring my boat. A cheaper buss bar will probably work just as good but might not be as corrosion resistant or nicely made. Depends on where your budget is and if you’re using it on a salt or freshwater boat. Would definitely buy again

Used product for gang grounds with heavy cable to frame but cover would not fit over heavy cable, okay for ground not positive buss bar with exposed terminals.

Quality Items for a Great Price !!

This worked great for my needs. I used it to add emergency equipment to a vehicle. I was able to screw it into the side of the car under the hood. I ran my power leads to this from the battery and then used the connectors to feed power to my relays. The screws are all very solid and it mounted well. The cover on top made me feel better about having those positive terminals exposed. I have no complains about this whatsoever!
