Review: Thick copper bar - Solid much better that 150 amps bus bar
Review: Great Bus Bars - I bought these as power distribution bus bars on one of my smaller solar power systems. These bus bars are made of tinned plated copper bus bars with a 300 amp rating. The bus bars are very strong with six 3/8" studs and protective covers. Great for heavy gauge cables moving lots of current. These bus bars are very capable and have high conductivity for a low resistance connection. If you want a great connection, make absolutely sure the bus bars are copper. They are very easy to install and have lots of room for expansion. These bus bars are a terrific value for the price. I highly reccomend them to anyone looking for good bus bars for solar, RV, Marine and other applications. I give them 5 stars.

### ⭐⭐⭐⭐⭐ These are well built, and do what they should
*by M***R on 23 June 2025*

Fantastic busbars. I'm in the process of installing Solar and a new inverter in my small RV. Having these busbars is way better that just bolting a couple of cables together. Its kinda amazing how many cables you can start putting together, plus it makes it easier to identify what goes where. Thanks again
