Concentric and split concentric cable explained - aluminium line conductor and a copper combined neutral and earth conductor in concentric cable. The split concentric cable has and aluminium line conductor and copper neutral and copper earth insulated from each other. We see how a concentric cable can be mistaken for a SWA (steel wire armour) cable coming into the bottom of a domestic cutout.
