Simple Installation

Connect the black wires to the hot lines at a convenient point load side of th fuses (breakers). Connect the white wire to the ground, and/or grounded neutral. To protect pumps it is important that a conductor is connected fromt he arrestor ground to the actual steel frame of the motor/pump. A wire from the arrestor ground point to the mteal tubing will do. If the tubing is plastic, connect to the metal casing, or next closest grounded metal.
