    10 HP = 7.46 kW, so allowing for start-up surge current you would need a supply rated for much more than 7.46kW (i.e. >> 31A @240V RMS).

    What is the voltage rating of the motor?
    (Anytime you want to offer more info about the motor without us asking, feel free to do so. :rolleyes:)

    240 VAC 40 amp circuit.

    I run a 15 HP in my shop off a 60 amp without issues.

    What is your country of origin?
    Do you have 3 phase available?
    Do you presently have the motor?
    If so what does the motor plate indicate?

    You will need a 3 phase supply, the most common is 460 if using in the US, Unfortunately it is out of the realm, size wise to be able to run it off a 1ph VFD, these usually top out at 5hp for the 1ph type.
    You will also require a disconnect, fusing and over load, current dependant on 240 or 460v operation.

    As I mentioned in earlier post, you will be hard pressed to find a VFD that will drive a 10hp with 1 phase in, most top out at 5hp when using 240v 1 phase..
    You could always try the support line of various suppliers, such as WEG, Mistubishi or Teco, or Hitachi.

    Yes it can be done. Most larger VFD's can be modified to work on higher powered single phase inputs as well. I've done several over the years for people.

    I just put in larger components to increase the input rectifier bridges current rating and main power bank capacitor values by 2 - 3 times their stock ratings.
