How many 12-2 wires through one hole?


I'm wiring a small house that is built with metal studs that have the four elongated holes in them. I'm using the standard 1" grommets that will fit one above the other in each hole. How many 12-2 Romex wires can I run in each hole before I have to derate them? Thanks

Useally 3 X 12-2 NM cable thru 1 inch hole is not a issue.

Just make sure you have the groument ring secured in and when you pull the NM cable make sure they are not kinked up or twisted up.

Merci.
Marc
