Re: CQD answer published Wednesday, September 14, 2018 -Suspended Ceiling Luminaires 3

Charlie, we have a local "more restrictive local law" (MRLS) in the City of White Plains that requires all recess lay in fixtures to be independently supported with two #12 wires or jack chain. The reason is our local firefighters have been struck by falling fixtures, some with sharp edges, during overhaul. This requirement was enacted during the early '70's when the fixtures were heavier and sometimes as large as 3' x 5' with eight lamps and four ballasts.

Since that time, it has become "standard" in the surrounding communities for the local inspection agency to ask for the same level of support. Ours is the only one that is recognized by the State of NY as an MRLS and is enforceable.  The other towns make it a "verbal" requirement.

Hey Richard thanks for your comment and the additional information. Local requirements can have more restrictive conditions that the NEC and can be enforced by the AHJ where they are in place. It is always best to check with them if there is any doubt - before doing the installation.
