Wire Ampacity Calculator–Content
- AmpCalc for Windows is a computer program from CalcWare which calculates power cable ampacity ratings and/or cable operating temperatures for user defined cable installations. Ampacities are calculated for single or multiple underground systems including:.
- Direct buried cable. Direct Buried conduit. Version 4.0 now includes calculations for aerial systems including:. Cables isolated in air. Conduit isolated in air. Cables in covered or uncovered cable tray.
- Calculations are in accordance with the industry accepted Neher-McGrath calculation procedures. AmpCalc is suitable for cable installations utilized in industrial, commercial and utility electrical power distribution systems.

The software is suitable for use with Windows 7, 8.1 or 10. Licenses for single computer, multiple computer and network applications are available. Refer to a partial experience list for some of the companies which utilize AmpCalc.
The Advanced Wire Ampacity Calculator will calculate the maximum ampacity for a wire based on wire gauge, preferred (or available) wire insulation, conductor type and installation specifications. This calculator also provides wire size correction factors for temperature, number of conductors in a raceway, and voltage drop for long wire runs.
This calculator is based on NEC (NFPA 70®: National Electrical Code® (NEC®), 2014 Edition) Table 310.15(B)(16-17).
