Bus Bar 12V-48V DC 300A, Heavy Duty Busbar Box with 4X 3/8" Posts Battery Terminals Blocks, Positive& Negative Ground Power Distirbution Block 300 Amp for Car RV Solar Boat Marine, 2 Pack

Designing a solar charging system with multiple batteries was a breeze with this 600 Amp bus bar. You don't want to risk the chance of using substandard materials and that is why, after much research, I purchased this product. One look and I could immediately tell it is made with the highest quality materials. The way it is designed lends itself to safety and a robust mounting ensures it will stay put. The covers are easily removable but also provide short protection when installed. It saved me time and money by reducing the lengths of wire I had to run when designing and building my solar charging project. Highly recommended.

Excellent choice for anyone needing reliable and robust power distribution. High-quality copper. Excellent conductivity and durability. Installation is straightforward. Heavy-duty construction. This bus bar offers great performance and value for its price.

I was hoping to find a solution for a tight space in a solar generator I'm building. The bus bars I ordered originally are long and take up an awkward amount of space and I went on the hunt for a better solution. This bus bar isn't cheap, but it's perfect! It's not overpriced, compared to other specialty type electrical components. Still, at around $45, they're obviously proud of their product (and they should be). The plastic housing feels extremely durable, it's clearly fiberglass reinforced. I had to go back and re-read the ad, and yep, they call it 'fiber and reinforced nylon.' The gauge of the steel used for the plate and the 3/8" lugs, I have no doubt that it can handle 400 amps. The max I'll ever place on it is 200 amps, it's a fused system.This was the ONLY bus bar I could find that was as compact as it is, but still had 8 x 3/8" lugs and I'm extremely glad that these turned out to be so nice.

Overall, highly recommend this product. The product is well made and sturdy. Although it only has 4 bolts, and no blank plates to close the unused cable openings, overall it’s a good pick and value.

Wow! Construction quality is unsurpassed, really nice and heavily made, I like the fact that the terminal covers are secured with fasteners for safety. And speaking of the covers, they are nice and thick, not just a flimsy snap on cover. I was pleasantly surprised by this product. Highly recommend

I needed a way to have auxiliary terminals upfront as my battery bank is at the rear of the vehicle . This is definitely quality and recommended just make sure you have three-quarter inch terminal ready

Worked perfectly and good quality. Very happy with this buss bar and would recommend it.

I used this in an RV DC system installation and they are great. They're heavy, solid, mount easily, and are well-protected. The snap-on covers stay on securely but are also easy to remove for service. I bought several of these to keep around the shop.
