Which of the following factors is NOT typically considered when selecting cable types for electrical installations?

When selecting cable types for electrical installations, several critical factors must be considered to ensure safety, functionality, and compliance with standards. Current capacity is essential, as it determines the maximum amount of current a cable can handle without overheating. The installation environment is also crucial; cables must be suitable for the conditions they will be exposed to, such as temperature extremes, moisture, or chemical exposure. Compliance with regulations is another vital consideration, as adherence to local and national electrical standards is necessary to ensure safety and legal approval.

Color coding and design, while important for identification and aesthetics, do not impact the performance or safety of the cable in the same way as the other factors. Thus, while cables may come in different colors or designs for ease of identification and visual organization, these characteristics are not a primary factor in the selection process. The focus during cable selection is primarily on functional aspects such as current capacity, environmental suitability, and regulatory requirements.
