AWG 10 Wire
Diameter 0.1019″
Millimeters 2.588 mm
Cross-section 10,384 cmil
mm² 5.26
Nominal bare-conductor dimensions per ASTM B258. AWG is geometric: d = 0.005 × 92(36−n)/39 in with n = 10; area is derived from the diameter. Ampacity depends on insulation, bundling, and the electrical code in force — it is a property of the installation, not the gauge.
