| 9.4.9 | Fishing cable from below a wall
When you run horizontal cabling in a building that has a basement, you can fish cable from there to the work areas on the first floor. To do this you must do the following: Drill a 3.2 mm hole, at an angle, through the floor, next to a baseboard. Push a coat hanger or stiff piece of wire into the hole to indicate the spot when you are in the basement. Go to the basement and locate the wire. Use a tape measure to mark a spot under the areas of the wall. This mark should be 57 mm from the hole. Drill a new hole in this spot. This hole should be 19 mm in diameter. Unlike the first hole that was drilled at an angle, drill this hole straight up through the subfloor and wall plate. Push the cable up through this second hole, to the wall opening where the work area outlet is to be located. Be sure to allow enough excess cable so that it can reach the floor and extend another 60-90 cm.
