New Construction Electrical Inspection Hint, by Joe Tedesco

[jtedesco1]

Nonmetallic-Sheathed Cable.

In both exposed and concealed locations where nonmetallic-sheathed cables pass through either factory or field punched, cut, or drilled slots or holes in metal members, the cable shall be protected by listed bushings or listed grommets covering ALL metal edges that are securely fastened in the opening prior to installation of the cable.

Here's another hint, the cables in this nonmetallic single gang box are supposed to be stapled with 8 inches of the box and the sheath is supposed to extend into the box for a 1/4 inch.
