Wire Gauge Calculator helps contractors and tradespeople accurately size, spec, and estimate materials and systems.

ସୂତ୍ର

Min Wire Size = Load Amperage / 0.8 (NEC 80% rule) → look up AWG table

ଷ୍ଟେପ୍-ଷ୍ଟେପ୍ ଗାଇଡ୍ |

  1. 1Calculate load in amps, apply 80% derating, look up NEC wire gauge table
  2. 2Apply the formula using your project measurements
  3. 3Add required safety factors or waste allowances per code

ସମାଧାନ ହୋଇଥିବା ଉଦାହରଣ

ଇନପୁଟ୍
20A circuit, 80% rule
ଫଳ
Min = 20/0.8 = 25A capacity → use 10 AWG

ଏଡ଼ାଇବା ଯୋଗ୍ୟ ସାଧାରଣ ଭୁଲ

  • Not applying code-required safety factors or derating
  • Forgetting to account for waste and cut losses in material estimates
