What is the minimum ampacity rating required for a duplex receptacle in an elevator hoistway pit?

The minimum ampacity rating required for a duplex receptacle in an elevator hoistway pit is 15A. This requirement is specified due to the nature of the environment and the potential load that may be required for equipment in that location. Elevator hoistway pits can house various electrical devices and systems, which necessitate a receptacle capable of safely handling the demands of such equipment without the risk of overheating or failure.

A 15A receptacle provides a balance between meeting the operational needs of the equipment while also ensuring safety standards in an area that may be difficult to access for regular maintenance. This helps ensure reliable performance for safety equipment and any auxiliary systems, such as lighting or maintenance tools that may require power in the hoistway pit.

Receptacles with lower ampacity ratings, such as 5A or 10A, would not provide the necessary power supply for the various potential loads in the area, which could compromise functionality and safety. Conversely, while a 25A receptacle could potentially handle more load, it exceeds the minimum requirement, and typically, the chosen ampacity aims to match the expected operational needs while maintaining safety and code compliance.
