Can an electrical distribution box be placed inside an elevator

An electrical distribution box can be placed inside an elevator building, but it must comply with NEC requirements for accessibility, clearance, and separation from elevator equipment.NEC Requirements and Safety ConsiderationsLocation and Accessibility: Electrical panels must be installed in a readily accessible area with sufficient working space: at least 30 inches wide, 36 inches deep, and 6.5 feet high in front of the panel, with the door able to open 90° (NEC 110.26, 408) . In elevator machine rooms or control spaces, panels must be accessible to qualified personnel only and should not obstruct elevator operation or maintenance . Separation from Elevator Equipment: While elevator machine rooms are primarily for elevator controls, it is permissible to install non-elevator electrical equipment, such as a distribution box for HVAC or lighting, provided it does not interfere with elevator safety or violate clearance requirements . Panels should not be installed in pits, hoistways, or other areas where personnel may be exposed to moving elevator components . GFCI and Receptacle Requirements: Any receptacles in elevator pits, hoistways, or machinery spaces must be GFCI-protected if rated 15A or 20A, 125V, to ensure safety for maintenance personnel . This applies to receptacles, not necessarily the distribution box itself, but any branch circuits serving the elevator must follow these rules. Mounting and Clearance: Panels must be firmly secured and have dedicated space from floor to 6 feet (1.8 m) for safe operation. Equipment should not extend more than 6 inches beyond the panel front, and the workspace must remain clear of storage or obstructions . The top of the panelboard should not exceed 6 feet 7 inches (2 meters) above the floor for safe access . Wiring Methods: Conductors in elevator machine rooms or control spaces must be installed in rigid metal conduit, EMT, wireways, or approved cable types unless specifically exempted for listed cord-and-plug equipment .Practical GuidanceSeparate Disconnects: For multiple elevators, it is common to install a panel in the machine room with separate disconnects at each elevator door for safety and code compliance .Non-Elevator Loads: Installing a distribution box for other building systems (e.g., air handling units) in the elevator machine room is allowed if it does not compromise elevator safety or violate NEC clearance and accessibility requirements .Inspection and Compliance: Always ensure that the installation meets local amendments to the NEC and is approved by the authority having jurisdiction (AHJ). Conclusion: You can place an electrical distribution box inside an elevator building, typically in the machine room or control space, as long as it meets NEC clearance, accessibility, and safety requirements, does not obstruct elevator operation, and is accessible only to qualified personnel. Non-elevator circuits can share the space if these conditions are met.
