## How much power does a 3 HP motor use?

Unit consumed = Power in kW X numbers of hours of operation. = **59.76 units**. Hence units burnt (consumed) by 3 HP motor in 24 hours will be 59.76, if the motor efficiency is 90% and motor is fully loaded.

## What size generator do I need to run a 3hp motor?

**A generator rated 3 kVA** will run a 3 hp motor. The engine that drives the generator may be rated 4 hp. If the motor load is hard starting, then you might need a larger generator, 4–5 kVA. Usually generators are rated in kilowatts, so a 3kW generator could be large enough, 4kW will work ok in most all cases.
