Calcolatore Codice Colore Resistenze
Decodifica il valore di una resistenza dalle bande colorate stampate sul componente.
A/cmil
Estimated Ampacity
12.3 A
Wire Area4,107 cmil
Estimated Ampacity vs AWG Gauge Number
Formula
## Wire Ampacity **I_max = Area x Current_Density** Typical chassis wiring: 0.003 A/cmil. Always check NEC tables for installations.
Esempio Risolto
14 AWG copper wire.
- 01Diameter = 64.08 mils
- 02Area = 4106 cmil
- 03Ampacity = 4106 x 0.003 = 12.3 A
Domande Frequenti
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.
