What is the diameter of a #14 AWG wire?

The diameter of a #14 AWG wire is actually approximately 0.064 inches. This size is part of the American Wire Gauge (AWG) system, which is a standardized wire gauge system used predominantly in the United States. Each gauge number corresponds to a specific diameter and, consequently, a specific current-carrying capacity.

Understanding the significance of wire size is crucial in electrical installations, as it affects not only the wire's conductivity but also safety and efficiency. A wire that is too small for its application can lead to overheating and may pose fire hazards. Thus, knowledge of the exact diameter is fundamental for selecting the appropriate wire for specific electrical applications.
