Switch Leg - which is correct?


Which is correct and why? Code reference if possible.

1) Power comes into light:
- White tied into white of fixture
- Black is tied into the black to the switch
- White from switch tied into black of fixture (taped black at both ends)

2) Power comes into light:
- White tied into white of fixture
- Black is tied into the white to the switch (taped black at both ends)
- Black from switch tied into black of fixture


Thanks for your help in advance!

You could wire it several differant ways.
You could run to fixture first then run a piece of 14/3 to the switch box .
If you do it that way take the nlack wire from the feed and tie it to the black or red from the 14/3 and run it to one side of switch.
Then use the other colored wire black or red for other side of switch.
The white wire just gets capped off in switch box as a future neutral.
At the fixture box the unused red or black from the 14/3 gets tied into the black wire from fixture.
The whites get tied together with the white wire from the fixture.

Interesting. But the 2 scenarios I describe - which is correct. I know they both work , just want to be code compliant.

#2 is correct, but new code requires a neutral at the switch location. No code ref.

All existing. Just changing fixture and replacing the switch.

So #2 it is?

The switch will work either of the 2 ways you posted.
You asked what was legal code wise, you didnt mention anything else as far as details.

Disregarding the neutral requirement, #2 is correct. No code reference, but the reason is so that you don't have two whites connecting to the fixture, even if one is taped.

Great, thanks everyone for the info.

Ironically I did read about having the neutral in the box for new stuff - I think it was so new switches/dimmers that need a neutral now have one.

Working, and correct isn't the same. I don't have the code ref., but you don't want to have two whites at the light fixture, even if one of them is taped or running to a black pigtail, as seems the situation here.

Maybe im missing something here, I thought I read he was labeling the extra white wire with black tape to identify it as a power wire.
Thats what im seeing with both ways he wrote it up.

Looks to me like hes identifying the white wire with black tape here, am I missing something here?
Or am I the only one that sees taped black on both ends of white wire in option one?
To me that means hes marking it with black tape in the light box and in the switch box, ive never seen an inspector tag something like that anyway.
Well I just looked up the article, makes no sense to me as to why they want it that way if its identified as power, but what ever makes them happy I guess.

Yes - the white wire is taped black at both ends (in the switch box and the fixture).

I too looked up Jim's reference NEC 2011 200.7 (c)(1) and it's all good.

Joed's response made since as well - don't want two white wires hooked up to the fixture - can cause confusion.

Does anyone have the NEC code reference for the neutral/grounded conductor to be present in the box?

I have NEC 2011 404.2 (a) exception.
