Rewire your fleet or build custom commercial trailer harnesses from scratch with the industrial-grade Truck-Lite 52700 7-Conductor Bulk Trailer Cable. Packed on a massive 1000-foot spool, this heavy-duty multi-conductor cable is engineered specifically for commercial vehicle body builders, fleet maintenance shops, and custom trailer manufacturers who demand reliable power delivery for lighting and braking systems.
The 52700 bulk cable features a robust 8/10/12 gauge configuration, utilizing high-performance General Purpose Thermoplastic (GPT) copper wiring. This combination of wire sizes is deliberately calculated for 7-way commercial trailer plugs to handle varied electrical loads across a single run:
8 Gauge (1 wire): Optimized for high-amp ground returns (White).
10 Gauge (2 wires): Perfect for heavy auxiliary power lines and ABS brakes (Red, Blue).
12 Gauge (4 wires): Ideal for standard running lights, stop/turn signals, and clearance marker circuits (Black, Brown, Green, Yellow).
Encased in a premium, oil-resistant black PVC outer jacket, this round bulk cable provides ultimate protection against abrasions, crushing, extreme weather, road salts, and automotive fluids. Its flexible design allows for smooth routing through tight conduit runs and along heavy-duty vehicle frames without binding or kinking.
