4MM TWIN SHEATH AUTOMOTIVE CABLE RED/BLK 30M ECA421-30

Built Tough for 4mm Automotive Cable Applications

This 4mm industry equivalent twin sheath automotive cable is designed for general automotive, trailer, caravan, 4WD, and marine wiring applications. With red and black conductors inside a durable black outer sheath, it is ideal for 12V and 24V circuits where clear polarity identification and neat installation are important. Suitable uses include trailer lighting, LED lighting, marker lights, switches, brake light wiring, indicator wiring, control wiring, and small accessory circuits.

Durable Twin Sheath Cable for Vehicle and Trailer Wiring

Made with twin-core construction and protective outer sheathing, this automotive cable is suitable for vehicle-based wiring where flexibility and easy installation are required. The red and black cores make it simple to identify positive and negative wiring during installation, while the black sheath helps protect the cable in general trailer, caravan, marine, and automotive use. This cable is a stronger option than smaller 2mm and 3mm industry equivalent sizes, but for higher-draw accessories such as 12V fridges, inverters, compressors, or long cable runs, a larger cable size should be selected.

30m Twin Sheath Automotive Cable for Trade and DIY Use

Supplied as a practical 30m roll, this cable is a convenient option for installers, electricians, auto electricians, trailer repairers, and DIY users who need reliable cable for repeated vehicle wiring jobs. It is suitable for trailer lighting, LED lighting circuits, small switches, indicator wiring, brake light wiring, and general automotive wiring. For higher current accessories or longer cable runs, choosing a larger cable size can help reduce voltage drop and improve performance.
