Voltage-Surge Protector
(Page 4 of 5)
To modify one of the devices, you must first split the
aluminum housing in half by removing eight screws, four in
each of the two end plates. However, this is easier said
than done. For some reason, the screws have recessed,
square-drive heads that require a special tool. I didn't
consider the tool to be worth buying, so-after several
false starts-I devised a way to get the screws loose. By
filing slots in the fasteners' heads with a triangular
file, I was able to remove them with an ordinary slotted
screwdriver. After I finally did get the screws out, I
promptly tossed them away (I replaced them with
conventional Phillips-head items).

Once the end plates have been removed, the lower half of
the metal case slides off, exposing the undersides of the
outlets. Begin the modification by removing a short strip
of insulation from each of the three wires connecting the
first two sockets together (looking at it from the
circuit-breaker end). A razor knife works best. Now solder
three MOV devices to these wires, bridging one
across the black and white wires, one across the black and
green, and one across the white and green. After soldering,
bend the leads so the MOV's rest against the backs
of the outlets, as shown in the photograph.
Next, work on the link that connects outlets two and three.
With a pair of wire cutters, completely remove a section of
the black and white wires between the two outlets, leaving
short pigtails connected to the second socket. Strip the
insulation from the pigtails. Do NOT cut the green wire!
