All major elevator manufacturers are offering machine room-less (MRL) systems. These systems eliminate the need for a separate room to house hydraulic pumps, control panels, etc. The controller must still be located so. Each car, machine room and hoistway pit must have separate dedicated branch circuits for lighting, receptacles and HVAC, with car and machine-room lighting exempt from GFCI while required for receptacles. Overcurrent devices and disconnects must be located in machine or control spaces, be lockable. A look at Article 620. Is there not? Has this changed OR should I be looking in the, in this case MA, elevator code for. A machine room is an area where the elevator drive unit, controller, and main disconnect switches are located. However, they do present some challenges.
