Review: Zero complaints! Very nice bus bar! - 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.
Review: Very nice distribution block! - Product is very durable and well made! Would definitely recommend!
