It has consistently been a contention of mine that where a manufacturer of a Listed luminaire or fan/light requires 90C conductor terminations, that the wiring in that box (the point of termination) be 90c rated. This topic for all intensive purposes is a real "110.3" issue and a 410 Listing and Labeling topic. I would like to know how others feel about this. Listing drives a lot of interpretation and puts teeth in actual articles not left to examination or interpretation. Antiquated cloth and TW insulation drives this thinking of mine and I am a believer that that is probably one of the main reasons for the Luminaire Labeling containing a 90C tag. FIRE AWAY PEOPLES!
