CT 6854-500-BK — 600 A PowerBar-class busbar with four 3/8"-16 studs on a black base, with two #8-32 screw terminals per end. Tin-plated copper bus on a black glass-reinforced UL 94 V-0 base, raised so two lugs land inverted and two upright on each stud — four terminals per stud within ABYC E-11.10.4. The black base marks the DC negative bus at a glance; pair it with the red-base 6854-500 on the positive side for a matched set. Direct cross for Blue Sea Systems 2104.
