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


A common question. You are probably measuring with a good digital meter.
You are seeing a "phantom voltage". There is capacitive coupling - as
between a hot wire and switched wire to and from the switch. This produces
a very small current, but produces a reading on a good high resistance
meter. A light bulb with pigtail leads will indicate if voltage is
actually present.


If it is phantom voltage being measured by a sensitive meter, you can often
prove it by measuring voltage between your left hand and your right hand.
They can be that sensitive.


I had disconected the string of lights and thats when I show the 67
volts. I just hooked up the lights and measured the voltgage and it
was 32 volts when the lights were hooked up. Once again this is in the
off position not just the dimmer being set to low. The dimmer has a
rocker switch and a slider. These voltgages are coming with the rocker
switch in the off position
