## Electrical Load Formula **Amps = Watts / Volts** **NEC Safety Factor = 125%** (for continuous loads) Breaker sizes are standard: 15A, 20A, 30A, 40A, 50A. Always round up to the next standard size.

हल किया गया उदाहरण

1,500W load on a 120V circuit with 125% safety factor.

  1. 01Amps = 1,500W / 120V = 12.5A
  2. 02With safety = 12.5 × 1.25 = 15.6A
  3. 03Recommended breaker = 20A
