Rough in pigtails


Please help a old man remember. When roughing in light boxes etc. what is the accepted method of signifying the hot wire from the switch. I think it use to be just bend it back or twist a pigtail. Can not remember.
Thanks

The correct method is to wrap it with black electrical tape. I've seen electricians use a black permanent marker to mark them black. I'm not exactly sure what the code book says as I don't have it near me but the inspectors pass it either way here.

I wasn't even sure he was talking about a switch leg, but if so, then yes, the white conductor must be re identified.

What I mean is if you see two black wires in a light box after rough in and drywall is up how do you identify which goes to the switch and which is hot. It use to be common to bend it or strip the end or something that I can not remember. Then who ever comes to install lights,fans etc. knows which is which. The drawing above on the left if you remove the light which black goes to light which to switch. Hope this clears it up.
This getting old s...t sucks. But the alternative is worse.
Thanks

They both go to the switch, no need to identify them, if you had 3 blacks in a box, then I would pigtail the hots together at the rough, so I still only had two wires when I came back. gotta keep it simple.

In the rough in of the light box, I would wirenut the grnds, tape the white switch leg with black and wirenut that to the source black. That will leave sw-leg blk and neutral for when the light is installed later. At sw box, tape the white with black and that's it.
I understand your original question about 'bend the wire back, twist a pigtail' etc., but everybody does it different.

Two wires, two terminals. It doesn't matter which goes where. The switch conects the two wires or disconnects them.

except for us anal folks that install the hotwire on the top screw terminal.

there is no code rquirement to indicate the hot or switchleg. Many in may area curl the switchleg or put a piece of tape on the hotleg, or is it the other way around? It is a matter of personal preference and i have seen many methods employed. If it makes a diff, all that matters is the trim guy knows how they are indicated.
