Organized Power Distribution for Serious Marine Electrical Systems
The Sierra FS46670 is a heavy-duty 2-step dual bus bar designed for marine electrical panels requiring clean, high-capacity power distribution. With 12 gang positions and a 150-amp rating, it provides a reliable central connection point for both positive and negative circuits — keeping your wiring organized, accessible, and safe.
The dual-step design separates circuit connections across two tiers, reducing clutter in tight panel spaces and making it easier to trace, service, or expand your electrical system over time.

Parts Desk Insights
Best suited for builders and refit projects where a single high-capacity bus bar needs to serve multiple branch circuits cleanly. The 2-step layout is particularly useful in panel boxes with limited depth — it keeps positive and negative runs separated without requiring additional hardware. Pair with a compatible Sierra FS40900 Fuse Block with Bus Bar & Cover or the Sierra FS46630 Dual Bus Bar for a complete distribution solution. Also consider the Sierra FS40840 12-Gang Fuse Block or Sierra FS40830 6-Gang Fuse Block for fused branch circuit protection.
