Overview:
T&E cable 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.
