2 core vintage lighting cables are not involved with an earth wire and we can use them with any electrical item (small appliances) with an outer surface which is made from non-conductive materials such as rubber, glass, plastic, ceramic, porcelain or Bake lite and also which are double insulated. The cable is made of only two cores; live and neutral since this is flexible, it will be of circular shape. 3 core vintage lighting cables are used to connect appliances such as lamps, any light, bulb holder or extension cables to the power outlet sockets.
