Not in the US, NEC 334.30(A).
Not in the US, NEC 334.30(A).Holes count.
Technically not legal, but may be okay if you tie it near a staple. Depends on inspectors mood.Does a hole count as securing NM within 12" of a metal box... or do I need to add a staple?
TIA
Edit: or another idea... how about zip tying to another wire?
