Sierra FS46690 Mini Bus Bar — 100A, 4-Stud
A compact, high-current distribution point built for tight electrical panels and auxiliary circuits. The FS46690 delivers clean, reliable power routing in a small footprint — ideal for boats where space is at a premium but electrical integrity is non-negotiable.
Four solid brass studs handle up to 100 amps continuous, making this an efficient solution for consolidating positive or negative feeds without the bulk of a full-size bus bar.
Compatible Applications
- Auxiliary power distribution on powerboats and sailboats
- Secondary bus for helm electronics, lighting circuits, or accessory feeds
- Tight panel installations where a full-size bar won't fit
- Supplement to a primary fuse block for unfused circuits
Parts Desk Insights
Best suited for installations where you need a dedicated distribution point for a small cluster of circuits — think nav lights, bilge pumps, or a secondary electronics feed. Pair it with a Sierra FS40830 6-Gang Fuse Block or Sierra FS40840 12-Gang Fuse Block for a complete protected distribution setup. If you need more studs or higher amperage, consider the Sierra FS46700 Mini Bus Bar (250A, 6-Stud) or the Sierra FS46710 Mini Bus Bar (250A, 12-Gang). For a dual-rail setup, the Sierra FS46600 Dual Bus Bar (100A, 12-Gang) is a natural step up.
