Question:
Hi, I know the troffers on grid must be affixed by wire to opposite corners and to ceiling. Do the wires have to be two independent separate wires or can one wire be looped - affixed to each corner and go up and be supported. So one or two completely separate wires per troffer to ceiling?
Thank you

Answer:
Hey Debra thanks for your question. The NEC does not require that luminaires in suspended ceilings be supported independently of the suspended ceiling by wires or other means. Even if independent support is provided, the luminaires must be securely fastened to the suspended ceiling by the methods stated in 410.36(B). Local requirements and areas subject to seismic events can be more restrictive than what is in the NEC. Check with the local building official for any additional rules in your area.
