A 3 phase electric meter is essential for calculating the 3-phase motor amps calculation by heavy electrical appliances. It is recommended to use this energy meter only when your load requirement is more than 5 KW to 7 KW. For a load lower than this, a single-phase energy meter is sufficient and much more economically viable.

To figure out how many amps does a motor with certain kW power have, we have to rearrange this equation a bit. We get the 3-phase current formula like this: I (Amps) = P (kW) × 1,000 ÷ (V (Volts) × PF × 1.732) Using this power formula, we can, for example, do a 3-phase motor kW to amps calculation.
