Manufacturers refer to number 14, 12, and 10 AWG size conductors as what type of conductors?

Manufacturers refer to number 14, 12, and 10 AWG size conductors as circuit size conductors because these gauges are commonly used for household and light commercial circuits. The American Wire Gauge (AWG) system helps determine the cross-sectional area of electrical conductors, with lower numbers indicating thicker wire capable of carrying more current.

In residential wiring, circuit size conductors are essential for establishing and maintaining electrical safety standards, ensuring the conductors can handle the expected load without overheating. These sizes are typically used for branch circuit wiring that supplies power to outlets, lighting, and appliances. Understanding these sizes allows electricians to select the appropriate conductor based on the current and load requirements of a specific circuit, thereby maintaining electrical code compliance and ensuring safe operation.

This classification does not apply to heavy-duty, primary, or secondary size conductors, which are typically used in different applications or for different purposes, such as power transmission or specialized industrial settings. Hence, "circuit size conductors" is the correct terminology for these AWG sizes.
