300.11 Fire rated Assemblies
Exception: The ceiling Support system SHALL be permitted to Support wiring & (EQUIPMENT) that have been tested as a Fire rated assembly.
As I see it then unless a Fire rated ceiling has been tested & approved. it requires additional support. Since its in the NEC as referenced I'd say we have to address it.
(Equipment)SEE Definations Article 100 includes Luminaires(fixtures)
All ceilings are listed & labled as to supports required.
I always tell Electricans to work with ceiling installers & to check and address it. To ignore it I feel & say its a building offical issue ??????
