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.
