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

सूत्र

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

चरण-दर-चरण मार्गदर्शिका

  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

हल किए गए उदाहरण

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

सामान्य गलतियां जिनसे बचना है

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