The CCS inspectors around here will not pass a job done in a drop ceiling unless all fixtures are chained regardless of the type.We have been told that a drop ceiling shall not carry any added weight including wire.
Lighting may rest upon a drop ceiling in order to get a good fit but the chains must also be tight.
As for pot lights in a drywall ceiling again i don't have a clue on a code rule # but usually the only thing that can fall is the reflector and it can't be chained so...
Some four foot fluorescent troffers can and will kill you no matter what type of ceiling it falls from so you have to use your "good judgement" and chain where morally necessary.Also a fixture that falls from 20' is more dangerous than 2'
All codes requirements are the absolute bare minimum,whether it's the CEC,Building or fire.
Understanding the SPIRIT of a code rule is as important if not more important then understanding the LETTER of a the code rule.
cheers
