The Ground Buss Bar Kit provides a single, versatile solution to create a central ground point at your site. The ground buss bars are manufactured from ¼ inch (6.3 mm) thick solid, tinned copper and incorporate 26 pairs of 7?16 inch (11.1 mm) holes and 26 pairs of ¼ inch (6.4 mm) holes. By slotting one hole in each pair of 7?16 inch holes, the ground buss bar accommodates any lug hole spacing from ¾ inch (19.1 mm) to 1 inch (25.4 mm). Six (6) pairs of 7?16 inch holes are incorporated for lug connections to the ground system. This item has been discontinued by the manufacturer and is here for archival purposes.
