Multi-Core Cable

AUTOMOTIVE MULTI-CORE & TRAILER CABLE

Our heavy-duty Australian Made Multi-Core and Trailer Cables provide flexible, color-coded circuit routing for trailer plugs, brake controllers, canopy lighting control, and multi-circuit switch panels. Available in 5-core, 7-core, and custom multi-core configurations manufactured by Tycab, Key Tubing, and Austech to AS/NZS 3808 standards.

Current Capacity & Circuit Sizing: Multi-core cables contain multiple active conductors packed tightly inside a common outer sheath. Carrying high continuous current through multiple adjacent cores generates significant internal heat buildup. Multi-core cable is optimized for signal, brake, and lighting circuits; dedicated single or twin core cables should be used for heavy continuous power feeds (such as caravan 12V charging).
