Figure out amperage from horsepower
WebCalculate the amp draw. We use the basic electric power equation for this. If we know the wattage and voltage, we can quite easily calculate the amp draw. Multiply amp draw by 1.25 to account for the 80% breaker rule. The resulting amps are the minimum ampacity a correctly sized circuit breaker should have. Choose a circuit breaker size. WebOct 30, 2024 · Rearrange the formula of hp to amps for the three-phase line-to-line system P = I × √3 × V × PF × η / 746. Apply the values (we can approximate the square root of 3 as 1.73 ), P = 0.5 × 1.73 × 100 × 0.8 × 95% / 746. The resulting power equals 0.088 hp.
