Inside Wire Job

[tonype]

Switch controls light in photo. However, connections are made in the panel. Lampholder neutral connected to the terminal bar. Power (black conductor) from lampholder wire-nut connected (yellow one at the bottom right) to neutral from switch. Black wire from switch is connected to breaker.

Is this a correct method of wiring?

Technically the white from the switch should be taped and connected to the feed. The black from the switch should be connected to the black from the light socket.

I always heard if using a 2 conductor cable for a switch the white should be the hot one, so when(or is it IF?) is tested it'd show hot all the times. Don't think it's really an NEC thingie. I don't see anything wrong, as far as that is concerned, as long as the white wire is reidentified with a black(or red) tape. Personally I would prefer it that way.
However....
The panel has 8 breakers, no main, and a bunch of grounds connected to the neutral bar. If it's a services panel and the neutral is bonded to the ground, then it's a violation of the 6 main rule. If it's not, than the ground wires can not be terminated on the neutral bar.
The feeder seem to be an SE cable(most likely 2 hots and a neutral) so not sure how getting the ground wires properly connected can be accomplished.
Also, seem the switch box doesn't have a connector(could be wrong)

Sub-panel. I have already called out the combined terminal bar use as a no-no. The switch as a connector - not visible in the photo.

Except in MA.


200.7(C). Delete the final sentence of (1), designate (2) as (3), and insert a new (2) as follows:

(2) If used for single-pole, 3-way or 4-way switch loops, the conductor with white or gray insulation or three continuous white stripes shall be used only for the supply to the switch but not as a return conductor from the switch to the outlet. In these applications reidentification of the conductor with white or gray insulation or with three continuous white stripes shall not be required.

Before the days of idiot-proofing the NEC you would use the white as the hot to the switch and the black as the switch leg. Now that the white is required to be re-identified does it really matter?

I guess that MA sees it that way also.

No. And it didn't need idiot proofing either. Even some idiots knew that a white wire that is part of a switch loop was not a neutral. Other idiots color doesn't matter one bit where it should, and yet they are concerned about color where it doesn't really matter.:slaphead:

Sounds more like DIYer proofing!!!!
