The electrical distribution box is installed under the elevator

Installing an electrical distribution box directly under an elevator is generally not recommended due to safety and code compliance concerns.Safety and Code ConsiderationsElevator electrical systems are governed by NEC Article 620, which sets strict requirements for wiring, equipment placement, and working clearances to prevent hazards such as electric shock, arc flash, and fire . Electrical conductors and equipment located below grade, including elevator pits, fall under these regulations. The NEC mandates minimum clearances around electrical equipment to allow safe access for maintenance and emergency situations, typically requiring a working space at least 30 inches wide and extending from the floor to 6.5 feet or the height of the equipment . Placing a distribution box directly under the elevator cab could obstruct these clearances and create a hazardous environment for technicians.Elevator Box Installation GuidelinesElevator power distribution boxes, especially three-phase elevator boxes, are usually installed in the machine room or near the elevator control panel, not under the elevator shaft . These boxes supply power to the motor, control board, and other elevator components. Standard installation height is around 120–140 cm from the floor, secured with bolts and rawlplugs, ensuring accessibility and compliance with safety standards . Installing the box under the elevator could expose it to mechanical damage, water ingress, or restricted access during maintenance.Risks of Under-Elevator InstallationElectrical hazards: Increased risk of shock or arc flash if the box is in a confined or wet area.Maintenance difficulties: Technicians may not have sufficient space to safely service the box.Code violations: Non-compliance with NEC Article 620 could result in legal and insurance issues.Mechanical damage: The box could be struck by elevator components or debris in the pit.Recommended PracticeFor safety and compliance, the distribution box should be installed in the machine room or a dedicated control space, with proper clearances and secure mounting. If space constraints exist, consult a licensed elevator technician or electrical engineer to determine an alternative location that meets NEC requirements and ensures safe operation . In summary, placing an electrical distribution box under an elevator is unsafe and likely violates code requirements. Proper installation in the machine room or near the control panel is the standard and safest practice.
