    Test for amperage draw

    There is a 240V circuit that feeds my geothermal unit. If I wanted to check for amperage draw when the unit starts could I just put my test meter around both wires or would I have to do each wire separately.

    Amp draw is usually done for each individual component that you want to measure, checking the draw of the combined total wont tell you if a single component is overamping
