*If your power rating is different than horsepower (HP), use the below calculations (or see video below) to find the proper HP rating to input into the Phase Converter Wizard.

**Please note these calculations are for 208 – 240 volts. If you are in need of a different voltage setup please call to talk with one of our sales associates.

Calculations:

• 240v amps / 2.8 = 240v HP

• KW * 1.342 = HP

• KVA = HP

• Watts / 1000 * 1.342 = HP
