    Correct wire size!

    ... wait a second... 22.5 kW or 22500 / 240 volts = 93.75 amperes...
    To be more accurate on the cable and breaker size, we need the applied voltage and phase!!

    I deleted an incorrect answer and confirmation.

    As requested, we need to know more details.

    There are restrictions on max circuit size to certain electric furnaces in certain locations, so we need to know where this will be installed, residential, commercial, etc.
