This is correct- also, one SNAFU to watch out for. In the case of
switches,
it is common practice to put a piece of black tape around the white wire
in switch circuits to indicate that the white wire is NOT a neutral
wire,
but has been used as a switch leg. (But I suppose some cost-cutting
companies
may not do this!) This is done where the power feed comes in at the
light
box on the ceiling instead of the switchbox on the wall. Sorry for
cluttering
up the Ten Tec reflector with treatises on house wiring! 73 all, -Web
