This came up on the job today, couple guys say its against code to have an occupancy sensor in a mechanical room, the prints say to do it. Something about the lights could turn off on the maintenance guys while the equipment is being serviced.
Is this an NEC rule, a NFPA rule, a local ruling, a rule of thumb, pure crap...anybody know?
(D) Illumination. Illumination shall be provided for all working spaces about service equipment, switchboards,panelboards, or motor control centers installed indoors. Ad-ditional lighting outlets shall not be required where the work space is illuminated by an adjacent light source or as permitted by 210.70(A)(1), Exception No. 1, for switched receptacles. In electrical equipment rooms, the illumination shall not be controlled by automatic means only
Gotcha. :thumbsup: Sounds like since all mechanical rooms have some sort of electrical equipment in them, this code has basically become the same for both.
Referring to the manual on/off to override the motion
