Key Notes

AWG and MCM: For sizes larger than 4/0 AWG, cables are expressed in MCM (thousands of circular mils). 1 MCM = 0.5067 mm².
Larger Diameters: Diameter increases proportionally with cross-sectional area for larger cables.
Current Capacity: Values depend on installation conditions such as ambient temperature, insulation type, and method of installation (e.g., in air, conduit, or buried).
Practical Use: Use this table for quick conversions. For exact specifications, refer to manufacturer datasheets or standards.

Example Usage

Metric to AWG/MCM: For a 400 mm² cable, the approximate size is 750 MCM.
AWG/MCM to Metric: For a 1000 MCM cable, the approximate metric size is 500 mm².
