learn.whatIsHeading

Voltage Drop Calculator helps contractors and tradespeople accurately size, spec, and estimate materials and systems.

Formül

VD = (2 × K × I × L) / CM where K=12.9(Cu), I=amps, L=feet, CM=circular mils

Adım Adım Kılavuz

  1. 1Enter circuit amps, one-way distance, and wire gauge circular mils
  2. 2Apply the formula using your project measurements
  3. 3Add required safety factors or waste allowances per code

Çözümlü Örnekler

Giriş
15A, 100 ft, 12 AWG (6530 CM)
Sonuç
VD = (2×12.9×15×100)/6530 = 5.94V = 4.95% (max 3% recommended)

Kaçınılması Gereken Yaygın Hatalar

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