What is the diameter of a #14 AWG wire most nearly?

The diameter of a #14 AWG wire is most nearly 0.064 inches. This size is specified by the American Wire Gauge (AWG) standard, which is a standardized wire gauge system that determines the diameter and current-carrying capacity of wires used in electrical applications.

In electrical wiring, it’s important to know the correct wire gauge because it directly affects the wire's ability to carry electrical current without overheating. A #14 gauge wire is commonly used in residential and light commercial applications for circuit wiring, particularly for general purposes like lighting and outlets.

Understanding wire sizes and their corresponding diameters is essential for ensuring safety and compliance with electrical codes. In this context, knowing the specific diameter helps electricians choose the appropriate wire for various projects, ensuring that it meets the electrical load requirements without exceeding its capacity.
