What does NFPA 220 and NFPA 5000 have in it with regard to wiring methods in schools?
Massachusetts has an exception to 334.12 (2) which allows NM above suspended ceilings in other structures...
But 334.10 (3) states that NM must be covered by walls ceiling etc...with material that has a 15 minute fire rating...and where can I view the "listings of fire-rated assemblies".
