NEWDetermine American Wire Gauge (AWG) diameter, cross-sectional area, electrical resistance, and maximum NEC ampacity.
How to use AWG Wire Gauge & Ampacity Calculator
- Select your target AWG wire size.
- Select the conductor material (Copper or Aluminum).
- Choose the insulation temperature rating (60°C, 75°C, or 90°C).
- Read the calculated wire gauge physical specs and NEC-compliant ampacity limits.
What is AWG Wire Gauge & Ampacity Calculator?
This AWG wire calculator computes electrical and physical parameters for standard solid wire sizes (from 4/0 AWG down to 30 AWG) using standard ASTM and NEC (National Electrical Code) specifications for copper and aluminum conductors.
FAQ
- What is AWG?
- American Wire Gauge (AWG) is a standardized wire gauge system used in North America for the diameters of round, solid, nonferrous, electrically conducting wire.
- What is ampacity?
- Ampacity is the maximum current, in amperes, that a conductor can carry continuously under the conditions of use without exceeding its temperature rating.
