What is the maximum voltage allowed in the hoistway?

The maximum allowable voltage in the hoistway is crucial for ensuring safety during elevator operation. 300 volts is the correct answer because this limit is established to prevent electrical hazards that could result from high voltage in areas where personnel may be working or where equipment may be inspected, maintained, or serviced.

This specific threshold is in line with safety regulations designed to minimize the risk of electric shock, fire hazards, and other potential dangers associated with working near high-voltage electrical systems.

Higher voltage levels can significantly increase the risk of severe injury, thus codes and standards for elevators commonly set this limit to ensure adequate protection for both operators and maintenance personnel.
