In an elevator system, which of the following is NOT typically considered when designing electrical circuits?

In the design of electrical circuits for elevator systems, the primary considerations include factors essential for the operational integrity and safety of the elevator. Lighting is necessary to ensure visibility within the elevator cabin and in control areas. Ventilation is important for maintaining air quality within the elevator shaft and cabin, particularly if the elevator runs within enclosed spaces. Heating may also be relevant, especially in climates where temperatures might drop to levels that could impact the components or the comfort of passengers inside the elevator.

The water supply, on the other hand, is generally not a consideration in the electrical design of elevators. Water does not directly influence the electrical components or circuitry involved in the operation and safety of elevators. While water supply might be relevant in other building systems, such as plumbing or fire protection, it does not play a role in the electrical design parameters for elevators, which focus on power distribution, control systems, alarms, and safety features. Thus, the water supply is the element that would typically not be considered when designing electrical circuits for elevators.
