Default Wiring Method

Hey guys! So, i started a new job with a company in SC and i am working with another co worker. We were roughing in a switch leg with the feed in the ceiling box. He asked me to make the connections in the ceiling box and first thing i did was put black tape on the white wire that goes to the switch, and join it with the black feed. My co worker saw what i did and said he doesn't do it that way and to join the black feed with the black going to the switch. Well, being from PA that is how i was taught so, i don't know if that's something they do in the south or what but in my opinion that way is incorrect. I ended up doing it his way so there was no arguement or debate on who's right.

So he would end up with 2 white wires for the fixture? That doesn't make sense.

There is no right or wrong (or code) way to do that. Just mark any white that is used as a hot.

Sorry but that is incorrect. The white wire must be used as the hot not the return.

I should have given the reference

Quote:
200.7 (C) Circuits of 50 Volts or More. The use of insulation that is
white or gray or that has three continuous white or gray stripes
for other than a grounded conductor for circuits of 50 volts or
more shall be permitted only as in (1) and (2).
(1) If part of a cable assembly that has the insulation permanently
reidentified to indicate its use as an ungrounded
conductor by marking tape, painting, or other effective
means at its termination and at each location where the
conductor is visible and accessible. Identification shall
encircle the insulation and shall be a color other than
white, gray, or green. If used for single-pole, 3-way or
4-way switch loops, the reidentified conductor with white
or gray insulation or three continuous white or gray
stripes shall be used only for the supply to the switch, but
not as a return conductor from the switch to the outlet
.

I usually mark it with a red sharpie at both ends, but I won't run a lot of switch legs these days. You never know what kind of fancy dimmer they might want down the line and it doesn't make sense break up the rhythm to bring out a spool of 14/3 just for switch legs.
