Voltage Drop Calculator helps contractors and tradespeople accurately size, spec, and estimate materials and systems.
ସୂତ୍ର
VD = (2 × K × I × L) / CM where K=12.9(Cu), I=amps, L=feet, CM=circular mils
ଷ୍ଟେପ୍-ଷ୍ଟେପ୍ ଗାଇଡ୍ |
- 1Enter circuit amps, one-way distance, and wire gauge circular mils
- 2Apply the formula using your project measurements
- 3Add required safety factors or waste allowances per code
ସମାଧାନ ହୋଇଥିବା ଉଦାହରଣ
ଇନପୁଟ୍
15A, 100 ft, 12 AWG (6530 CM)
ଫଳ
VD = (2×12.9×15×100)/6530 = 5.94V = 4.95% (max 3% recommended)
ଏଡ଼ାଇବା ଯୋଗ୍ୟ ସାଧାରଣ ଭୁଲ
- ✕Not applying code-required safety factors or derating
- ✕Forgetting to account for waste and cut losses in material estimates
