Twin & Earth cable - 624Y / 624B

Our BASEC-approved Twin & Earth cable (also known as T&E) is a flexible flat sheathed mains electricity wiring cable used in a wide range of domestic electrical applications with a voltage rating of 300/500V. It can be installed in fixed wiring installations in dry or damp premises clipped to surface, on trays or in free air where there is no risk of mechanical damage. It is suitable for laying in conduit or trunking where mechanical protection is required.
Twin and Earth cable is a general fixed wiring and lighting cable, containing three conductors. As the name suggests, there is a pair or Twin current carrying conductors, both individually insulated, and one bare conductor which is the central protective circuit (CPC) or Earth. We supply Twin & Earth cable with PVC outer sheathing (6241Y, 6242Y, 6423Y and 6244Y) and LSZH sheathing (6241B, 6242B, 6243B, 6244B) - the last of the four digits in the designation relating to the number of cores in the cable.
