Elevator Machine Room Disconnects | Information by Electrical
The client wants to put an Equipment Branch panel in the elevator machine room that will have nothing to do with the elevators. Rather it is to serve two Air Handling Units.
Other electrical distribution boxes should be placed in the elevator machine room
Only electrical equipment directly related to elevator operation is permitted in an elevator machine room; other distribution boxes or unrelated panels are generally prohibited.Code and Regulatory RequirementsElevator machine rooms are intended to house driving machines, motor generators, controllers, and auxiliary control equipment necessary for elevator operation. According to California Code of Regulations, Title 8, Section 3011, only machinery and equipment required for the operation of the elevator may be installed in the machine room. Any other equipment or materials unrelated to elevator function are not allowed, and the room must be kept clean and free of obstructions .The National Electrical Code (NEC) 620.37 and Oregon Electrical Specialty Code (OESC) specify that only wiring, raceways, and cables used directly in connection with the elevator or dumbwaiter are permitted inside machine rooms. Conduits or raceways for unrelated electrical systems may not enter the machine room unless strictly necessary for elevator devices .Practical ImplicationsSeparate feeds: Each elevator should have its own dedicated feeder or disconnect within the machine room. Installing a general electrical panel to serve multiple elevators or other building systems is typically not allowed .Access and safety: Machine rooms must have proper access doors, clearances, and barriers to ensure safety and compliance with ASME A17.1 and state codes .Exceptions: In some older installations (pre-1947 in California), certain equipment may exist in shared spaces, but modern codes require dedicated enclosures for elevator machinery .SummaryIn summary, other electrical distribution boxes unrelated to elevator operation should not be installed in the elevator machine room. Only equipment and wiring directly associated with the elevator, such as motor disconnects, shunt trip breakers, and control circuits, are permitted. Any additional electrical panels must be located outside the machine room in a dedicated electrical space to comply with NEC, state, and ASME standards .
