Installing Inside House Wire.
Inside house wire comes in rolls that are usually 500 to 5000 feet in length. This wire is used
to make the electrical connection between the station protector and the connecting block. All
information in regards to installing wires in a building apply to this wire also. Installing the wire is
relatively easy. Usually the wire is inserted into the predrilled hole from inside to outside. More wire is
needed inside than outside. To secure the wire to the protector follow these procedures:
a. Remove 4 inches of outer insulation from the wire.
b. Wrap yellow and black wires from top of insulation downward (6-8 wraps).
c. Insert the house wire through the rubber boot. Bring it up into the protector and through the
center hole to the two "I" terminals. Connect the red wire to the "I" terminal on the right and the green
wire to the "I" terminal on the left. Be sure the wires are between the washers and are wound in a
d. Mark 1/8 inch on standing side with needlenose pliers next to the "I" terminals. Now remove
insulation from both red and green wires. Replace the wires to the "I" terminals and tighten.
e. Approximately 2 inches below the rubber boot secure the house wire with a staple. This
removes the tension from the terminals. At a point 2 inches before entering the predrilled hole secure
the house wire and protect it as it enters the hole to get inside. Use friction tape if necessary to protect
the wire from abrasions at the entry hole.
Connecting blocks should be used when making connections between wires, cables cords,
and so far, on desks, tables, baseboards, beams, windows or door frames, or other permanent woodwork
either in rooms, cellars, or basements. The No. 42A connecting block is most commonly used, it has
four terminals and comes equipped with a plastic cover that is held in place by a single screw. See
