FAQs

This set includes one red bus bar for positive connections and one black bus bar for negative connections. Additionally, the package contains 32 wire lugs: 24 of the #8 size and 8 of the 1/4" size.
Each bus bar is rated for a maximum operating voltage of 12-48V DC and a maximum current capacity of 180A. Each block features 12 individual terminal ways for your connections.
These distribution blocks are designed for use in automotive, marine, and solar power systems. They are also well-suited for golf carts, RVs, and car audio installations where multiple power or ground connections are required.
Each bus bar measures approximately 5-5/16 inches in length by 1-1/8 inches in width (135mm x 30mm).
Because these are constructed with stainless steel components, they offer good resistance to corrosion. However, ensure that all wire connections are properly crimped using the included lugs and that the bus bars are mounted in a location protected from direct water submersion to maintain the integrity of your electrical connections over time.
