Joinfworld Bus Bar 12V 250A Power Distribution Block 4 x 3/8" Studs Marine Bus Bar 12 Volt Battery Busbar Terminal Block for Automotive, Car, Boat, Solar Wiring - Negative&Positive

Well built. Good price. Should do the job for my boat’s electrical system.

Very happy with the product. Worked perfectly for my situation

Great product

I've been using the bus bar in my custom 24V power bank, which runs at 100 amps, and it works like a charm. The bus bar handles the high current effortlessly, ensuring stable power distribution across my setup. The construction feels robust, and the 3/8" studs provide a secure connection for my cables. One feature I particularly appreciate is the cover, which adds an extra layer of safety by protecting the terminals from accidental contact. This is especially important in high-power applications where safety is a priority. The installation was straightforward, and it integrates well with my existing components. I haven’t encountered any issues with overheating or instability, which speaks to its quality and reliability. The only minor downside is that the cover can be a bit tricky to snap on and off, but once it's in place, it stays secure. This bus bar is an excellent choice for anyone needing a reliable power distribution solution for automotive, marine, or custom power setups. It delivers solid performance and peace of mind, even under demanding conditions.

Good quality and Heavy duty

This was exactly what I was hoping they would be. I am rewiring the entire electrical in my 56buick. These bus blocks are exactly what I was hoping for

21July2023 = M10 or 3/8in. busbars from Joinfworld appear to be of excellent build and quality. Busbar (copper plate only) thickness is about "2 Dimes" thick.... I'm hoping that'll be enough to handle their claimed 250 Amps. I'm also hoping that the seller's claim that it's a pure (tinned) copper busbar is true and that I didn't buy brass busbars. I'd have to say their pricing is about $5.00USD too high but, oh well. I made this purchase on the claim that it can handle 250 Amps AND that it's a copper busbar and not brass. I guess only time will tell. I'm hoping the pictures and video I posted will help you decide. There's about 1/2 an inch of "lug/terminal" space on each of the 4 main bolts. Only two small 'sink' screws hold the busbar to the baseplate/housing. There's probably room for one terminal on the 3 smaller screws. These busbars have a good weight to them and (again) definitely feels like a great quality product. I actually purchased two sets of busbars.... this one and also the M8 or 5/16in. busbars which is also a 250A busbar. The M8 busbar posts have just a little over 1/2 inch of "lug/terminal" space. The M10 busbar itself (actual busbar copper plate only) weighs about 1.2 oz. Thanks Amazon, Amazon Employees and Joinfworld for a great product.

The cover on each bus does not fit if you have any wires worth a damn in size. I had to take off the covers just to fit a simple battery mount on. It still works just fine though.

Great, heavier duty than expected. Solid piece, great value for the price.

Solid . They worked great for my solar set up panel.

Good heavy duty bus bars. Only negative is they are not weather proof, so make sure to cover connections with dielectric grease after everything is together.

Solid and affordable

Good quality; works as expected
