Additions to the old cables mean that some installations will have mixed colours within them. In the old IEC color code, all the lines in three phase supply are either brown or black. The DIN and French ferrule colour code repeats colours, particularly as conductor sizes increase. Cable D (Fig 2) is a three core and earth, this is the ‘3 wire control’ that links the two light switches together. IP67 2P+E straight cable socket,16A 110V.
