Our 3 Core and Earth Rubber Cable

3 Core and Earth rubber cables—often called 4 Core—are built for serious industrial jobs that require three active conductors plus an earth. Perfect for powering three-phase machinery, heavy-duty tools, and temporary switchboards, these cables combine excellent flexibility with high resistance to oils, abrasions, and UV. Guages range from 1.5mm² up to 10mm², with current ratings from 20A to 66A. Available in a variety of lengths. Built to meet AS/NZS standards, they’re trusted on job sites, event setups, film sets, and in portable power systems across Australia.
