Strange lighting wiring
Hi All,
I have some 12v spotlights in my bathroom. I needed to move one so disconnected it some time ago and have eventually cut the new hole today. Having now forgotten which way it was wired I thought I should check with a multi meter to be on the safe side. It is 3 core and earth and the results (all AC) are as follows
With switch off
Grey - brown 146v
Grey - black 240v
Brown - black 76v
With switch on
Grey - brown 240v
Grey - black 240v
Brown - black 0v
So for this I conclude that
Grey is neutral
black is perm live
Brown is switched live
Is this correct ? More worryingly any idea why I am getting spurious voltages when the switch is off?
Thanks in advance
Lee.
