Load side of be starter to the motor. Control power from the line side of the starter to the pressure switch and back to the coil, through the overload contacts. Coil voltage must match line voltage . Don't be one of those d!cks that use the 240V supply to the coil and wire to ground to obtain power for a 120V coil. Time to hire a pro before you burn the place down, cripple or kill somebody. You hire a pro to do your dental work . [Reply]   [No Email]

Like he said, ground wires are not there for you to wire into a circuit. [Reply]  [No Email]
