Question:
Good Morning,
Our question is about clearance from metal roof decking. Can I mount a fluorescent luminaire directly to the metal deck with sheet metal screws?
Thanks,
Peter Reed
A
Answer:
Peter,
Section 410.10(F) indicates that luminaires installed in exposed or concealed locations under metal corrugated sheet roof decking shall be installed and supported so there is not less than 1-1∕2 in. measured from the lowest surface of the roof decking to the top of the luminaire.
