I still have a large voltage at my light when its turned off?
I am a fully qualified electrician and I am currently doing a small wiring job in a 3phase farm house in France. I have wired a lighting and power circuit in a bedroom and when I I turned it live it all works fine,the sockets the 2-way switching etc. However when I put my volt tester on the ceiling pendant I had 130v when the switch was off, same on the wall lights there was a 50v reading. If I put the bulbs in it then works fine switching on and off, and when off no voltage but take out the bulb I have voltage there again. I thought it could be a problem with the neutrals but found none , I checked the rest of the house and the problem is the same all over 150v in one place. I'm on a hourly basis so don't want to spend hours investigated if anyone else could help me who might have encountered this problem before?Thanks in advance!
