Calcolatore Codice Colore Resistenze

Decodifica il valore di una resistenza dalle bande colorate stampate sul componente.

A/cmil

Estimated Ampacity

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.

  1. 01Diameter = 64.08 mils
  2. 02Area = 4106 cmil
  3. 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.
