    Correct wire size!
    Just curious to find out what size wire would need to be used for an electric furnace that is 22.5 kw,and what size breaker would need to be used for this furnace as well!!

    ... 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.
