What is the minimum size circuit conductor required for Motor #2 between the panel and the wireway?

When determining the minimum size circuit conductor required for a motor, it's essential to consider factors such as the motor's full-load current, the type of conductor insulation, the ambient temperature, and any applicable derating factors.

In typical electrical code references, conductors are sized according to the full-load current of the motor they supply. For many motors, such as those used in residential or light commercial applications, the National Electrical Code (NEC) provides guidelines that include factors like the type of conductors and their installation environment.

If the full-load current of Motor #2 is low enough to fall within the allowable limits for a 12 AWG conductor, then this is the appropriate choice. A 12 AWG conductor can typically handle up to 20 amps, which is suitable for many smaller motors, provided that it complies with additional requirements regarding voltage drop and ambient temperature.

If the motor's requirements or the installation specifics indicate a higher full-load current, larger gauge conductors would be needed. However, without specific details about Motor #2's full-load current, if the answer of 12 AWG is provided, it would suggest that the application scenarios align well with the operational design intended for that motor setup, ensuring safety and regulatory compliance.
