Brand: Blue Sea Systems
Part Number: BSS-1991
Official Product Type: High-Current DC Busbar
Rating: 1000A
Studs: 12 x 3/8”-16
System: Electrical / DC Power Distribution
The Blue Sea Systems PowerBar 1000 BSS-1991 is a heavy-duty copper busbar rated to 1000 amps, built for high-current DC power distribution in demanding marine applications. This kit includes the busbar and a protective cover. With 12 x 3/8”-16 threaded studs, it provides more termination points than the 8-stud BSS-1990 — ideal for larger vessels or complex electrical systems with multiple high-draw loads.

- High-current positive or negative bus in engine rooms and electrical panels
- Multi-load systems: inverters, windlasses, bow thrusters, winches, and pumps

- Any application requiring a 1000A-rated 12-stud busbar
Key Features
- 1000A continuous current rating
- 12 x 3/8”-16 threaded studs for heavy-gauge cable terminations
- Includes protective cover to shield live connections

Parts Desk Insights
The BSS-1991 is the right choice when a customer needs more than 8 termination points on a single bus — most commonly on larger twin-engine vessels, live-aboard boats, or any installation with a high number of independently fused loads. Customers with simpler systems should consider the BSS-1990 8-stud version, which is more compact and lower cost. The included cover is a key safety feature; confirm the customer is aware it ships with the busbar to avoid duplicate cover orders.
