How do you calculate the current of a 3ph motor?
How do I calculate a 3-phase motor horsepower? You can use this equation HP = amperage × motor voltage × power factor × efficiency × 1.73205 / 746 to calculate the power rating of a 3-phase motor in horsepower.
What is 480V?
480V is the voltage between phases of a 3-phase “Y” circuit that’s 277V from hot to neutral. In keeping with 110V versus 120V strangeness, motors intended to run on 480V three phase are often labeled as 440V.
How do you calculate the full load current of a 3 phase motor?
I= P/(1.732*V*Cos pi) Here three-phase full load current is equal to the power divided by 1.732 times of line to line voltage and power factor.
What size conductor is required for a 5hp single phase motor which is powered from a 208 volt electrical panel?
A: The full-load current of a 5-horsepower, 208-volt three-phase motor is 16.7 amperes according to Table 430-150. The motor branch circuit conductors must have a minimum capacity of 125 percent of motor full-load current to comply with Section 430-22. This results in a minimum conductor ampacity of (1.25 x 16.7) 20.9.
What size conductors are required for a 5hp single phase 208v motor?
How many amps does a 5.5 kW 3 phase motor draw?

| 9.3 kW | 12.5 | 34 |
How do you calculate the horsepower of a 3 phase motor?
Triple Phase Electric Motor To find the horsepower of your triple phase motor, you’ll need to use this equation: HP = volts x full load amps x percent efficiency x power factor x 1.73 / 746.
How do you calculate full load amps on a 3-phase motor?
Formula used in Motor full load current calculator
- Single Phase AC Motor FLA (Amperes) = (P [kW] × 1000) / (V × cos ϕ)
- Single Phase AC Motor FLA (Amperes) = (P [HP] × 746) / (V × cos ϕ × η)
- Three Phase AC Motor FLA (Amperes) = (P [kW] × 1000) / (V × 1.732 × cos ϕ)
