mps @ 240 volts and you are plugged into 20 amp 120 volt outlets, you will need to turn the pressure down to lower the amp draw. Just turn the pressure regulator / unloader knob counter clockwise. The less pressure, the less horse power is needed to turn the electric motor and this will lower the amp draw.
Until both 120 volt power cords are connected to a 120 volt electrical source, it is electrically isolated from the electrical circuit of the non plugged in side on the 2nd power cord. This protects the user from accidental shock through the plug contact.
