INSTALLATION
If there is a surge so strong that something must be damaged, we prefer that our arrestor be
damaged rather than your equipment. Since we expect the arrestor might be damaged,
install it in a regular electrical enclosure to protect personnel from accidental contact with live
parts. Should the arrestor be damaged, it will not damage other components in the box. If the
arrestor cannot be placed in an enclosure, consider using our vent valve model. Its case will
not rupture. A small vent on the bottom of the case will open.
To protect a submersible pump motor, connect the black wires to the line terminals and the
white wire to the casing and/or tubing.
To protect equipment on a radio tower or a drilling rig, mount the arrestor to a junction box at
the bottom of each string of lights going up to the tower. Connect the black leads to the
circuit conductors and the white wire to the rig steel. Arrange for the conductors feeding the
junction box to be parallel with the earth. Connect an arrestor to the generator leads
grounding the white wire to the generator frame. Connect an arrestor to each lighting panel
connecting black wires to the circuit conductors, and the white wire to the box and rig frame.
To protect a house, the arrestor should be mounted on an outside switch or junction box, or
in the breaker box. The black wires should be connected to the circuit. The white wire should
be connected to the neutral, the box, and/or a solid ground. Model numbers G have a
separate ground wire.
To protect electronic equipment such as computers, transmitters, receivers, etc., connect the
black wires to the terminals of the device and the white wire to chassis. Mount the arrestor in
the cabinet. Consider using a surge capacitor connected to the breaker feeding them.
To protect a watt-hour meter, connect the black wires to the line terminals, and the white wire
to the meter box.
To protect an electric motor on machinery, connect the black wires to the motor leads and
the white wire to the motor frame.
Where the switch and motor are within six feet of each other, one arrestor will protect both
provided a solid ground wire is fastened to the switch box, motor frame, and arrestor white
wire. However, optimum protection is afforded only when the arrestor is connected directly to
the device to be protected.
To protect a motor control switch separately, connect the black wires to the line terminals
