I wired my finished basement myself.

When I switched off basement room receptacles circuit breaker while
all others except sub-panel which does not seem to affect the problem
were on we found there is 8 V power in that circuit. Switching off
some of other circuits reducing this voltage to about 2 V and only
switching off all new circuits brings disconnected voltage to zero as
it should be.


If you were reading this voltage at the recept with nothing plugged in
on that circuit, then the 8V is perfectly normal reading and is due to
stray coupling between conductors.

8V seems high. I rarely see more than a few hundred mV from inductive
coupling alone.

To the OP: Did you test every outlet with a tester to verify that all
neutrals are connected? I wonder if you have a floating neutral somewhere.
