we are doing a project where they want to reuse exisitng 2x4 laying fixtures T8. The fixtures had been 277 now the new circuit for lighting is 120v and the fixtures are missing the small J box cover with green screw that is normally on fixture. I have a 2 part question
first Can I supplement the J box cover with a fabricated cover and 1/2'' knockout and ground screw and still be cover under NEC and UL listing of fixture ? I was thinking of screwing a handy box cover with 1/2'' ko they self tapping a ground scew, what you think is this OK?
Second Since the ballast was already tapped at 277 will the 120v ballast take to new voltage, I keeo hearing it wont work. I am going to try tomorrow and see if it does But I will give no guarantee they will stay on. Also these fixtures are in ware house with OS sensor. Is there a specific ballast i should be using for this application any way to work with OS, like a rapid start ? The fixtures are pretty old and not sure what is already mounted I will check morning
