Wire Gauge Size Chart

A wire gauge size chart, also known as a wire gauge table or wire gauge chart, it is a reference table chart that specifies the diameter, area and thickness of electrical wires. It represents wire sizes in both the American Wire Gauge (AWG) system and the metric system (millimeters or square millimeters).

Some of the key points you need to understand when reading a wire gauge size chart:

  1. AWG Gauge Numbers: American Wire Gauge is a standardized wire gauge system used in the United States to note the diameter of electrically conducting wire. In the AWG system, lower gauge numbers represent thicker wires.
  2. Cross-Sectional Area: The chart includes the cross-sectional area of the wire in square millimeters (mm²).
  3. Diameter: A mil is a unit of length equal to 0.001 inch.
  4. Current Ratings: Some charts include recommended current-carrying capacities for different wire sizes based on specific conditions.
