The OEX ACX1837 is a 12-way negative bus bar designed to pair with the ACX1836 fuse box to create a complete, compliant fuse distribution and grounding system. The ACX1837 is not a standalone product it is the negative side companion to the ACX1836. Rated to 32V DC and 100A, it features 12x M4 stainless steel grounding screws for individual circuit ground connections and 1x M5 stainless steel common recessed mounting point. Supplied as a single unit. Covered by a one year warranty.
A properly wired fuse distribution system requires both a positive fuse distribution point and a corresponding negative grounding point. The ACX1837 provides the negative side of the ACX1836 system, giving each of the 12 circuits a dedicated M4 grounding screw for a clean, organised negative return path rather than routing all negative leads back to a single chassis ground point separately.
The M5 common recessed mounting point connects the bus bar to the main negative feed, while each of the 12 M4 terminals provides an individual ground connection for the corresponding circuit. All hardware is stainless steel for corrosion resistance in automotive, marine and caravan environments. The 32V DC rating covers both 12V and 24V vehicle electrical systems. The 100A total current rating handles the combined load across all 12 circuits.
Designed for the ACX1836 fuse box: Pairs with the ACX1836 to create a complete positive fuse distribution and negative grounding solution. Not suitable for standalone use.
12x M4 stainless steel grounding screws: Individual M4 grounding point for each of the 12 circuits for a clean, organised negative return path.
1x M5 stainless steel common recessed mount: Single M5 common connection point for the main negative feed.
32V DC rated: Suits both 12V and 24V vehicle electrical systems.
100A total current rating: Handles the combined load across all 12 circuit terminals.
Stainless steel hardware: Corrosion-resistant hardware for long-term reliability in automotive, marine and caravan environments.
One year warranty: Covered by a one year OEX warranty.

What voltage systems does this suit? The ACX1837 is rated to 32V DC, covering both 12V and 24V vehicle electrical systems.
What is the total current rating? The ACX1837 is rated at 100A combined across all 12 terminals.
Why use a dedicated negative bus bar instead of individual chassis grounds? A dedicated negative bus bar provides a single, organised negative return path for all circuits, reducing the number of individual chassis ground connections and simplifying wiring. It also makes fault finding easier since each circuit's negative return is clearly identified and terminated at a single point.
