The basic requirement is for minimum clear distances of various depths for equipment operating at 600 V or less nominal depending upon voltage to ground and lateral distance to insulated or grounded surfaces or exposed live parts not an issue in elevator machine rooms. ASME Code requires that the temperature within an elevator equipment room be maintained between 55 and 110 degrees F non-condensing. Shunt-trip voltage monitoring and control circuit tied into Fire Alarm System.

Where more than one disconnect is required for a multi-car group the disconnects shall be adjacent to each other with the first disconnect located within 610 mm 24 inches of the open side of the machine. Space heating is rarely required and thus has not been addressed here. Sprinklers located in elevator machine control rooms and hoistways shall be rated at 212 degrees.

Wide or the width of the equipment whichever is greater. NEC 62062 requires the elevator disconnecting means fused switch or circuit breaker to selectively coordinate with all supply-side overcurrent devices. The temperature and humidity range shall be permanently.

AHJ Agency having Jurisdiction requirement All sprinkler risers and returns shall be located outside the hoistway machine roomspace or control roomspace. Elevator driving machines motor generator sets controllers and auxiliary control equipment shall be installed in a room or enclosure set aside for that purpose. 762mm for other spaces specified in Sections 3011e2 and 3011e3.

Elevator safety is a critical consideration for builders who have state safety codes to follow permits to obtain and regular inspections to pass.

These regulations are not intended to supersede applicable local building codes establishing higher standards. Live parts not an issue in elevator machine rooms. We resume with a look at wiring.

Electrical Component NEC Clearances. The elevator machine and controller must be located in the elevator machine room. Each sprinkler branch line shall terminate in the elevator.

And as the designer you can become the. For facilities not located in a flood zone locate hydraulic elevator machine rooms on the lowest landing served by the elevator. For hoistway pit and machine-room lighting must be located How unsupported lengths of traveling cables are measured In Part One of this series ELEVATOR WORLD April 2012 we began an examination of National Electrical Code NEC 2011 mandates for eleva-tors and related equipment installa-tions.

Cab length is at least 51 with at least 54 from the back of the cab to the face of the door. This section requires each 125V single-phase 1520A receptacle installed in pits hoistways on the cars of elevators and dumbwaiters associated with wind turbine tower elevators on the platforms or in the runways and machinery spaces of platform lifts and stairway chairlifts and in escalator and moving walk wellways to be of the GFCI type. Given that elevator equipment produces a substantial amount of heat space cooling is typically required.

Clearances around all electrical equipment in the elevator machine room shall comply with NEC 110-26 electrical clearances requirements. Selective coordination is also required for multiple elevators per NEC 62062.
