Another thing I found out the hard way is that the white wire isn't
always safe under some circumstances. It turns out that two commonly
used circuits were wired to the same breaker, and I wanted to move one
of them.
I move the black one first, but when I moved the white one, I touched it
and got a shock. Evidently, something on that circuit was on, and that
loose white wire was now black...and hot. Ouch!
