Which aspect is NOT typically considered when determining conductor size?

When determining conductor size, several factors must be taken into account to ensure safety and efficiency in electrical systems. Typically, ampacity, voltage drop, and environmental conditions play significant roles in this determination.

Ampacity refers to the maximum amount of electrical current a conductor or device can carry before sustaining immediate or progressive deterioration. It is critical to select a conductor that can handle the expected load without overheating, making this a key consideration.

Voltage drop is another important factor that involves calculating the difference in voltage at the source and the load over the length of the installation. Excessive voltage drop can lead to inefficiencies and affect the operation of electrical equipment, necessitating consideration of conductor size to mitigate this issue.

Environmental conditions, including factors like temperature, exposure to chemicals, and installation conditions (such as burial in the ground or placement in conduits), can also impact the choice of conductor size. Different environments can alter the ampacity ratings of conductors.

However, when focusing on the aspect that is not typically considered, the length of installation alone does not capture the broader requirements. While the length of the conductor run is relevant due to its impact on voltage drop, it must be evaluated alongside other elements like load current, type of insulation, and installation environment, rather than
