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?

There is a rule for electric rooms.

(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

The problem is the NEC does not define electrical equipment rooms.

Almost all rooms have electrical equipment in them.

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.

I disagree
I dont agree or disagree on this, im the one asking the question here :). Prints say to put one in. Couple guys that work this area alot are saying its come up in the past as a problem with the inspectors. Im looking for code references or peoples past experiences here.
