Where should the lighting for an elevator hoistway pit be sourced from?

From the general lighting circuit
From a separate branch circuit
From a shared circuit with other receptacle outlets
It is not required

The correct answer is: From a separate branch circuit

Sourcing lighting for an elevator hoistway pit from a separate branch circuit is crucial for safety and compliance with electrical codes. This requirement is based on the potential for hazardous conditions in hoistway pits, which may contain water or other substances that could pose risks. A dedicated branch circuit ensures that the lighting operates independently, providing reliable illumination without interference from other electrical loads that could lead to circuit overloads or fluctuations. Furthermore, having a separate circuit allows for better maintenance and access during service without impacting other lighting or receptacle outlets in the building, thus enhancing safety for maintenance personnel. This practice aligns with safety regulations applicable to elevator installations, which often mandate distinct circuiting for hoistway lighting to reduce risks and ensure compliance with the National Electrical Code (NEC) and local adaptations for elevator installations.
