Wiring lights in a shop
I am in the process of trying to get some lights in the mezzanine in my shop. The wire is run in the attic and I am just unsure of how to run the wire through the corrugated tin on the ceiling. Can I just simply drill a hole in the tin and run the wire into a junction box, or do I have to cut a hole in the tin that is the same size as the junction box? I do have a 2x6 between the trusses for the junction box to screw to. I just don't know if I can sandwich the tin in between or if it has to be cut out. Hope this makes sense. Thanks.

Welcome to the forums!
What kind of cable was run in the attic? IF it is NM cable I would suggest cutting a larger hole (1 3/8" 1" trade size) and install plastic bushings so the tin does not cut the cable sheath. It might even be easier to run the cable directly into the light fixtures then installing junction boxes. Either was you can run the cables into the back of the box or light fixture. Just make sure to use a fitting where the cable enters the KO of the box or fixture.

Ya its NM Flat. I was planning on just going with one junction box and then wiring all my fluorescent lights in series with conduit in between.

Would the fitting in the KO not work as a bushing against the tin? since it would be pushed up in the hole in the tin and the 2x6 behind it. or is that not right?

If there is any chance of abrasion I would use a bushing on the hole.
