Hi all, working on a 500W halogen today (just went to change bulb for inept owner) and found that there was 3V on the terminals when disconnected via the MCB. Its a TNC-S with a ZE of 0.15 and a ZS of 0.96 on that circuit. Its controlled by an IP66 switch with no earth facility. Any idea's why that 3V is still sat their with it all turned off?
