This is a 600 amp buss bar with 12 mounting positions for 5/16" bolts, used to consolidate multiple battery or inverter cable connections onto a single conductive rail. It's built for installers who need to join several parallel battery cables or terminal lugs at one common point without daisy-chaining ring terminals onto a single stud.
A buss bar like this one is a passive conductor — it has no active components to fail, but its performance depends entirely on clean, torqued mechanical connections. Copper or plated copper buss bars distribute current across multiple parallel cable runs, which reduces the number of ring terminals stacked on a single lug and lowers connection resistance at each junction point. Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
- 600 amp continuous ampacity rating.
- 12 mounting positions, each sized for a 5/16" bolt.
- Black finish (housing/insulator color as supplied).
- NOT rated to exceed 600A continuous draw — do not oversize downstream breakers or cabling beyond this bar's rating.
- NOT compatible with ring terminals or lugs drilled for bolt sizes other than 5/16" without a hardware adapter.
- Voltage rating [NEEDS VERIFICATION] — not provided in manufacturer data supplied for this listing.
- Solid conductive bar designed to consolidate multiple parallel cable terminations at one point.
- 12 bolt positions reduce the need to stack multiple lugs on a single terminal stud.
- 600A rating supports higher-current parallel battery or inverter cable runs.
- Black finish for the bar housing/insulation.
