What is an earth screen?
An earth screened 3 phase lead is internally the same as a normal 3 phase extension lead. What makes it different is the addition of a tinned copper braid around the diameter of the cable that is then covered by another UV stabilised rubber outer sheath. The tinned copper braid is then connected to the earth pin at the plug and socket end so if the lead is damaged then there is more potential for the electricity to flow to the earth path tripping the RCD, or earth safety protection device, preventing electrocution to personnel and protecting equipment.
