Branch circuits in an elevator system serve the specific purpose of providing power for lighting, ventilation, and heating within the elevator. This ensures that the elevator cabin is a comfortable environment for passengers, especially in commercial or residential buildings where elevators are frequently used. Proper lighting enhances visibility, making it safer for passengers to enter and exit the elevator, while ventilation and heating contribute to overall comfort, particularly in extreme weather conditions.

In contrast, while safety features are crucial for elevators, the primary role of branch circuits is not dedicated to these additional safety systems. Although distributing power to multiple elevators is a function of the larger electrical distribution system, branch circuits themselves are more focused on the specific needs of individual elevator cars. Monitoring electrical consumption, while important for energy management and efficiency, is typically handled by other systems rather than the branch circuits that directly power the elevator functions.
