Each of the five cores — three phases, neutral, and earth — uses finely stranded tinned copper conductors, giving the cable the flexibility to handle constant movement, coiling, and vibration without conductor fatigue. The tough black outer sheath resists oil, abrasion, and the general punishment of a workshop floor, making it the go-to choice for trailing leads, machine tails, and three-phase extension leads.\u003c\/p\u003e\r\n\u003cp dir=\"ltr\" data-sourcepos=\"12:1-12:437;963-1399\"\u003eColour-coded cores (green\/yellow earth, blue neutral, and brown, black, and grey phases) follow the standard identification used across Australian three-phase installations, so termination into plugs, sockets, and machine terminals is quick and unambiguous. Because the conductors are tinned, the cable also resists corrosion in humid, coastal, and marine-adjacent environments — a real advantage for Queensland workshops and site work.\u003c\/p\u003e\r\n\u003cp dir=\"ltr\" data-sourcepos=\"14:1-14:268;1401-1668\"\u003eWhether you're building a three-phase extension lead for a MIG welder, re-tailing a compressor, or running flexible supply to HVAC and pump equipment, this cable delivers the current capacity of 4mm² conductors with the handling ease of a fully flexible construction.\u003c\/p\u003e\r\n\u003cp dir=\"ltr\" data-sourcepos=\"16:1-16:16;1670-1685\"\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cul dir=\"ltr\" data-sourcepos=\"18:1-22:71;1687-2156\"\u003e\r\n\u003cli data-sourcepos=\"18:1-18:96;1687-1782\"\u003e\n\u003cstrong\u003eThree-phase ready:\u003c\/strong\u003e Five cores covering three phases, neutral, and earth in a single cable\u003c\/li\u003e\r\n\u003cli data-sourcepos=\"19:1-19:100;1783-1882\"\u003e\n\u003cstrong\u003eTinned copper stranding:\u003c\/strong\u003e Superior flexibility, vibration resistance, and corrosion protection\u003c\/li\u003e\r\n\u003cli data-sourcepos=\"20:1-20:99;1883-1981\"\u003e\n\u003cstrong\u003eHeavy-duty sheath:\u003c\/strong\u003e Black outer jacket resists oil, moisture, abrasion, and mechanical stress\u003c\/li\u003e\r\n\u003cli data-sourcepos=\"21:1-21:104;1982-2085\"\u003e\n\u003cstrong\u003eStandard AU colour coding:\u003c\/strong\u003e Green\/yellow, blue, brown, black, grey for fast, compliant termination\u003c\/li\u003e\r\n\u003cli data-sourcepos=\"22:1-22:71;2086-2156\"\u003e\n\u003cstrong\u003eCut to length:\u003c\/strong\u003e Sold per metre so you only buy what the job needs\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003ch2 dir=\"ltr\" data-sourcepos=\"24:1-24:28;2158-2185\"\u003eTechnical Specifications\u003c\/h2\u003e\r\n\u003cdiv dir=\"ltr\" data-sourcepos=\"26:1-34:88;2187-2642\"\u003e\r\n\u003ctable\u003e\r\n\u003cthead\u003e\r\n\u003ctr\u003e\r\n\u003cth scope=\"col\"\u003eFeature\u003c\/th\u003e\r\n\u003cth scope=\"col\"\u003eSpecification\u003c\/th\u003e\r\n\u003c\/tr\u003e\r\n\u003c\/thead\u003e\r\n\u003ctbody\u003e\r\n\u003ctr\u003e\r\n\u003ctd\u003eCores\u003c\/td\u003e\r\n\u003ctd\u003e5 (3 phase + neutral + earth)\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd\u003eConductor size\u003c\/td\u003e\r\n\u003ctd\u003e4.0mm²\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd\u003eConductor type\u003c\/td\u003e\r\n\u003ctd\u003eFlexible tinned copper, multi-strand\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd\u003eCore colours\u003c\/td\u003e\r\n\u003ctd\u003eGreen\/Yellow (E), Blue (N), Brown, Black, Grey (phases)\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd\u003eVoltage rating\u003c\/td\u003e\r\n\u003ctd\u003e450\/750V\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd\u003eSheath\u003c\/td\u003e\r\n\u003ctd\u003eBlack, oil and abrasion resistant\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd\u003eTypical use\u003c\/td\u003e\r\n\u003ctd\u003eWelders, machinery, three-phase extension leads, HVAC, workshop power\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003c\/tbody\u003e\r\n\u003c\/table\u003e\r\n\u003c\/div\u003e\r\n\u003cp dir=\"ltr\" data-sourcepos=\"36:1-36:30;2644-2673\"\u003e\u003cstrong\u003eFrequently Asked Questions\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cp dir=\"ltr\" data-sourcepos=\"38:1-39:270;2675-2984\"\u003e\u003cstrong\u003eWhat is 5 core 4mm² cable used for?\u003c\/strong\u003e 5 core 4mm² flexible cable is used to supply three-phase equipment such as welders, air compressors, machine tools, and HVAC units.
