Default Wiring Question Phanton Power when switch off

I wired up some lights with a dimmer switch. When I have the switch in
the off position I am still showing 67 volts. That is accross the
Netural( White) and the Load (Black) Wire. If I measure between the
netural and ground it is Zero and if I measure between the Load and
ground I get 67 volts. Where have I gone wrong. Thanks for the help



You didn't say whether those "some lights" were fitted with bulbs when
you made your measurements. If they were, and they are incandescent
bulbs, then what you wrote is highly unlikely.

I'm betting that the bulbs aren't in place and all the previous folks
who said your meter is just responding to a very weak microamp sized
capacitively coupled current are correct.

If the bulbs are in place, but they are not glowing dimly or at least
feeling warm to the touch after that 67 volts has been applied to them
for some time, then you need a get a pro in there to figure out what
kinds of electronic poltergeists have invaded your home.

HTH,

Jeff
