The smallest circuit conductors that can be installed between the wireway and the safety switch for Motor #3 are ___ AWG.

In determining the smallest circuit conductors that can be installed between the wireway and the safety switch for Motor #3, it is essential to refer to the National Electrical Code (NEC) and the specifics related to the motor's load, operating characteristics, and the current-carrying capacity of the wires.

For most applications involving motors, wire sizing is based on the motor's full-load current rating, as well as factors such as the length of the run and any potential voltage drop. Generally, a conductor must be appropriately sized to handle the expected load with a reasonable margin for safety.

In this case, the correct answer suggests that 10 AWG is the smallest acceptable conductor size for this motor application. The NEC stipulates specific minimum conductor sizes based on certain criteria, including the ampacity of conductors, which can vary based on insulation type, installation conditions, and the characteristics of the load (in this case, the motor).

While larger wire gauges (like 8 or 6 AWG) could technically handle more current, using conductors that are too large for the application can be inefficient and unnecessary, potentially leading to other issues such as difficulty in handling and increased material costs. Conversely, using a wire size that is too small
