Does This Look Right?


I am rewiring the lights in my garage and replacing all of the switches. They are probably around 40 years old. The wiring is a mixture of K&T and older romex style of wiring (12 gauge just white and black, gray outside, no ground). One of the switches had a white and a black (romex) wire going to it BUT there was NO black tape on the white wire. This is the main reason for my question. I'm guessing who ever did the wiring was just sloppy, but you guys have more experience and I wanted to pass this by you first to make sure they were just sloppy.

Below is a picture of the light that goes to the switch. The way it looks to me they connected the white switch wire to the black K&T, the black from the switch to the light and the white K&T to the light.

It looks like they just didn't put black tape on the white switch wire, right?

I know Code says to re-identify white wires as hot, but isn't it pretty damn obvious that the white going to the black is NOT a neutral, otherwise there'd be a short?

When there is a white wire on a switch that also has a black (hot) wire, isn't it obvious that the white is a switch loop, otherwise, again, there'd be a direct short when the switch is closed?

When there are two white wires on a light fixture, then we know that an idiot wired it, and there, I could understand (and appreciate) the re-identification of one of the whites. Still, a simple non-contact tester should be enough to indicate which is hot.

In short, I just think the re-identify rule is stupid.

Good to hear. Just wanted to be sure. I'll run a ground to the fixture and clean up the connections. Thanks.

Yes, you are most likely correct. I'm sure it is done all the time. Our entire house (built in the 70s) consists if switch loops and i've never noticed any of the white wires re-identified.

Looks more like 60 years old vintage not 40 years old.
