[QUOTE="Phoenix, post: 440663, member: 8133"] Seems quite normal to me, a disconnected earth on a lighting circuit that has any flouro battens or HF fittings, or basically anything slightly 'leaky' will go to somewhere around half supply volatage when measured with a high impedance instrument. Yes 30mA would trip the RCD, but I'd doubt you'd have that much.... how were you measuring it, and if auto ranging instrument could have been 30 micro-amps? Just this afternoon I located an open circuit cpc on a row of flourescent battens down a corridor with the use of a volt stick... Why the courgette was your mate opening the cpc to a cirucit that was energised? [/QUOTE]
