Crawlspace and Basement

Prior to entering a crawlspace or an unfinished basement, look and make sure that your planned entry point is

not blocked by plumbing or unexpected obstructions like spoil left during construction. It may be possible to bring

the cable through the crawlspace entrance. If not, use a masonry bit to drill through the foundation. Insert a feed-

thru bushing and pull the cable through; allow plenty of extra cable for reaching the outlet on the main floor.

In a finished basement, plan your point of entry as close to the ceiling as

possible and drill from the inside. Place your feed-thru bushing and run the

cable to the inside. With a hung ceiling, you may be able to run the cable

on top of that, attaching the cable to floor joists. Otherwise, run the cable

around the top edge of the room, and then cross to your ceiling entry paral-

lel to the walls. Wire mold can be used to hide the cable.

Finding the Wall From Below

At the outlet location, trace and cut your outlet hole. Then use a stiff, sharp

piece of wire to drill a pilot hole right at the base of the toe molding (to

leave no sign of a pilot hole at all, remove the toe molding and drill from the base of the remaining molding or

the drywall). When you feel you’ve broken through the floor, detach the wire from the drill and leave it

in the floor.

Go under the floor and locate the wire. Measure

in about 1 in (2.5 cm) (more if you drilled in at a

very steep angle) and, using a thin bit, drill a pilot

hole straight up to make sure you’re in the wall. En-

large the hole to accommodate the cable and pull

through enough for easy connectorization.

Use cable clips to attach cable to the floor joists.
