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.
- 01Amps = 1,500W / 120V = 12.5A
- 02With safety = 12.5 × 1.25 = 15.6A
- 03Recommended breaker = 20A
अक्सर पूछे जाने वाले प्रश्न
What is the NEC 80% rule?
The National Electrical Code requires that continuous loads not exceed 80% of the breaker rating (or equivalently, the breaker should be 125% of the load). A 20A breaker handles 16A continuous.
