![]() ![]() The maximum current for power transmission is less. Data from Handbook of Electronic Tables and Formulas for American Wire Gauge. ![]() This data from Floyd, Electric Circuit Fundamentals, 2nd Ed. *The AWG system states areas of round copper wires in "circular mils", which is the square of the diameter in mils. This table uses this value of resistivity, but it is known to vary by a few percent based on purity and process of manufacture. This table corresponds to a resistivity ofįor copper at 20 C. wire gauges (called AWG gauges) refer to sizes of copper wire. 8 THHN comes stranded with variety of colors and lengths. 8 Gauge THHN wire contains Copper (CU) Conductors. 8 AWG commercial wiring for outlets, switches and other loads.
