Wire Gauge Calculator helps contractors and tradespeople accurately size, spec, and estimate materials and systems.
Formel
Min Wire Size = Load Amperage / 0.8 (NEC 80% rule) → look up AWG table
Schritt-für-Schritt-Anleitung
- 1Calculate load in amps, apply 80% derating, look up NEC wire gauge table
- 2Apply the formula using your project measurements
- 3Add required safety factors or waste allowances per code
Gelöste Beispiele
Eingabe
20A circuit, 80% rule
Ergebnis
Min = 20/0.8 = 25A capacity → use 10 AWG
Häufige Fehler vermeiden
- ✕Not applying code-required safety factors or derating
- ✕Forgetting to account for waste and cut losses in material estimates
