## Customer Reviews

### ⭐⭐⭐⭐⭐ This Heavy Duty Bus Bar, Saves Time and Money.
*by G***S on March 17, 2025*

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.

### ⭐⭐⭐⭐⭐ Great performance
*by J***Z on August 27, 2024*

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.

### ⭐⭐⭐⭐⭐ Zero complaints! Very nice bus bar!
*by A***T on December 22, 2023*

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.
