AWG Reference
Organize conductor dimensions and resistance data for field verification.
AWG selection requires verified conductor construction, insulation, temperature, ampacity, resistance, and termination data.
Record
- Material, AWG/kcmil, stranding/class, insulation type, temperature rating, and manufacturer.
Use
- Use verified dimensions for fill and verified resistance for voltage-drop work.
Common mistakes
- Treating all conductors of one AWG as the same outside diameter.
- Using a 90°C ampacity where terminations limit the circuit.
Verify
- Check the adopted code tables and manufacturer data for the exact product.
