I need to rehang commercial grade track on a suspended ceiling. I know it needs to be suported from the building structure and not the grid but the customer is asking me what year did the NEC change the code? I am thinking this happened 8- 10 years ago. Can anyone clarify?
Is this covered under 410-104 or is it a different section?
We are required to support the track lighting independent of the ceiling grid in the great state of Mecklenburg, NC. I use a tool purchaced at a ceiling supply house that attaches to a 10' section of rigid pipe and a caddy fastener that snaps onto red iron or primary metal joists. Hope this helps.
