Wire Ampacity Rechner
Schätzen Sie safe current capacity for copper wire by AWG gauge.
A/cmil
Estimated Ampacity
12.3 A
Wire Area4,107 cmil
Estimated Ampacity vs AWG Gauge Number
Formel
## Wire Ampacity **I_max = Area x Current_Density** Typical chassis wiring: 0.003 A/cmil. Always check NEC tables for installations.
Lösungsbeispiel
14 AWG copper wire.
- 01Diameter = 64.08 mils
- 02Area = 4106 cmil
- 03Ampacity = 4106 x 0.003 = 12.3 A
Häufig Gestellte Fragen
What affects ampacity?
Wire gauge, insulation type, ambient temperature, and bundling.
Is this NEC rated?
No. NEC ratings depend on specific conditions. This is an engineering estimate.
What happens if exceeded?
Wire overheats, insulation degrades, fire risk increases.
