Our Twin and Earth cable, also known as 6242Y, or T and E, is a range of flat cables in grey PVC sheath. This type of flexible power cable is commonly used within fixed wiring applications for domestic and commercial applications. Operating at a low voltage, for applications such as sockets and switches, Twin and Earth are usually installed within dry environments, where mechanical stress is minimal. As the name suggests, T and E is constructed with 3-conductors, a current pair both individually insulated and a single bare conductor, namely the earth.
