Generally no, but there are circumstances where this does occur. When it
does the white wire will have a piece of black tape on it to let the
electrician know that this wire is now a "hot" conductor in both the ceiling box and the switch box. This will
occur when the power source comes in at the light fixture box and not at
the switch box. This now requires that the hot be transferred to the
light switch box via the white wire from the light fixture box and then
returned back to the light fixture from the switch on the black wire, to
give the switch control of the light fixture. Get other answers to mobile home electrical repair problems by visiting the website http://mobile-home-repair.blogspot.com/2015/04/mobile-home-electrical-repair.html l.
