Relocating light fixture, need to extend 2-wire circuit

Iím relocating and replacing a ceiling fixture. The new location is just a few inches away. The original circuit isnít grounded, and need to be extended a few inches to reach the new location.

I was going to connect a short 12ga Romex to it without grounding with wire nuts, but Iíve read somewhere that Iím not allowed to extend an old circuit with no ground, or install new receptacles with it.

Are these restrictions applicable to my situation?

That is correct. .

That's true, but no one's going to know.
You do need to add a junction box in the attic with a cover.
Why 12-2, it only needs 14-2.
Good luck trying to get that texture on the ceiling to match.

Also any splices are required to be in an accessible junction box. It can not be buried in the ceiling.

I kept the old box and spliced the wires inside with wire nuts. I labeled inside the boxes ďungroundedĒ and chopped off the remaining ground wire ends. The old wires were 12ga so thatís the size Romex I used.

Now Iím scratching my head about the proper cover for the old box. The ones I saw at HD were chunky but I need to make it seamless with the sheetrock.

You can get a canopy blank that will cover the box. Whatever cover you use needs to be accessible so you aren't going to be able to blend it into the sheetrock 100%.

Mulberry Ceiling Canopy blank for 3-1/4 in. Box - White-40431

Hot ground wire?

I mounted the fixture and it lights up. But when I checked with a pen tester I noticed that the base was hot. It turns out that the green ground wire is hot, and because it connects to the screw on the base, the fixture base is hot. Again, this circuit doesnít have ground. The instructions for the fixture say that if there is no ground in the junction box, I should just attach the green wire to the green screw.

Why would the green wire wire be hot? I checked everywhere, itís not touching any black or white wires.

Give the non contact tester to your kid tp play with. To actually test you need a multimeter, preferably analog, or even a test light. A non contact tester can't be used for real testing.

Iím only trying verify that the lamp body is safe to touch. I have a multimeter and measured no voltage between an extension cord ground and the green wire, and no continuity. So I think itís good.
