• C. 4'
• D. 5'

Answer: (C)

The minimum clearance required between the controller and the controller disconnect in the machine room is specified as 4 feet. This clearance is important to ensure safe and accessible maintenance procedures, as well as to accommodate electrical wiring and components without risking interference. Adequate space helps prevent accidents and allows technicians to work efficiently without the risk of being cramped or hindered by other equipment.

Furthermore, complying with this requirement ensures adherence to safety codes and practices, which is crucial in elevator installations and maintenance. The 4 feet clearance ensures there is sufficient room for any necessary repairs or inspections without compromising safety or accessibility.
