Ceiling fixture wiring question
 

I'm replacing a ceiling light fixture in my kitchen, we've only lived
in the house a few months. I removed the old light and in the junction
box there are four romex cables coming into the box and the wires for
the light.
So let's call the four Romex cables C1, C2, C3 and C4.

The first 3 are easy, C1, C2, C3 all have their black wires tied
together and all have their white wires tied together (and all ground
wires together).
C4 confuses me a bit (but that's not that hard to do), The black from
C4 goes to the light, the other wire from the light goes to the group
of white wires all tied together which makes sense...but the white
from C4 is tied into the group of black wires. Why would that be? I
would think that the white from C4 would get tied in with the white
wires, not the black wires....does this make sense?
Many thanks

C4 is a switch leg. White takes current to the switch, and it comes back to
the light on the black.

c4 is your switch. the white in it should have been taped black.

It was necessary to wire it that way to include the wall switch in the
circuit and have a black wire and a white wire feed the light fixture. If
you were to open up the switch you would find that the white wire is hot and
the black wire is the load feeding the fixture. If the black on the switch
was hot and the white was the load you would end up with two white wires
feeding the light fixture. This wiring scheme is normal and an accepted
practice.

Do not make any changes to the wiring. Just disconnect the two wires from
the existing light fixture and connect the new light fixture to them.

"we've only lived in the house a few months."

Just curious...what does this have to do with the situation?

Thanks alot for the answers, that makes sense. I have one more
challenge though. The location of the current junction box is not
correct. I actually need to install my light about 1 foot away from
the current lights' location. So I can't just connect the new light to
where the current light is. My plan was to put a cover on the junction
box that is there now.
Then install a new junction box in the new, correct location. So I
guess what I need to do is bring into my new junction box C4 (from the
switch) and C3? Then wire the black from C4 to the light fixture and
take the white from C3 and wire to the other leg of the light
fixture? Then obviously continue the wiring on the old, existing
junction box.
Does that make sense?

I'm going to do that. Thanks

I'll go home and bake a nice apple pie for you this evening. Since I
have no way of getting it to you, I'll eat it for you also.

I is usually easiest to add a new romex from the old j-box to the new
box. Connect to the wires that feed the light in the old box.


c4 is your switch. the white in it should have been taped black.

I'm going to do that. Thanks

Taping is another method that is used. The wiring is compliant with
the NEC as is. (Tape it if you want to.)

Yes, that definitely seems easier. Thanks!

It is not done, as a rule, by professional electricians. The NEC refers to
it all right, but it is optional. To say that it "should" be done is absurd.

Hmmm...lessee...Nope, can't find where is says you SHOULD tape the white in
the NEC.

(Hint: It's not done)

Ceiling fixture wiring question
 

Yup. That's the way I always read it too. What's more, and probably even
more important in this sort of situation, is to have the end at the switch
taped and identified so someone opening the switch won't think a white wire
is a neutral.

You didn't look very hard

200.7(C)(2)Where a cable assembly contains an insulated conductor for
single-pole, 3-way or 4-way switch loops and the conductor with white
or gray insulation or a marking of three continuous white stripes is
used for the supply to the switch but not as a return conductor from
the switch to the switched outlet. In these applications, the
conductor with white or gray insulation or with three continuous white
stripes shall be permanently reidentified to indicate its use by
painting or other effective means at its terminations and at each
location where the conductor is visible and accessible.


tape is considered an effective means.
