Noticed the other night that our energy saving bulb was lightly flickering every so often when switched off so decided to change the rose. When I thought about it more wondered how it could pulse when switched off...
Checked the circuit and found 12v on both the earth and neutral when nothing was switched on (power was on at board though). Started checking switches & roses on other lights and found the earth (inc screws on switches) were carrying 12v also.
Finally, in one room found that if I switched the light on, the earth in a lot of the other rooms rose to 36V.
I assume this is one of two things...
1. The earth is not going anywhere so picking up a current from the other cables
2. There is an incorrectly wired or damaged component / wire somewhere.
Anyone got any ideas where I go from here or why this may be happening?
Thanks
Graham
