Planning the Cable Run/Upper Floor

Visually inspect the outlet locations for electrical wires, plumbing, HVAC ductwork, windows and other impedi-

ments. Use the interior walls whenever possible. This way, you avoid installation headaches like trying to push

cable through insulation or around windows, or reaching under a roofline with a drill.

In the example below, all of the outlets can be reached from the attic. The phone outlet in the home office can

also be reached from the exterior by running a cable up to the eaves and then across and down to the outlet lo-

cation (consider a coax/UTP combination cable for this location). For the interior CATV outlets, a home run back

to the NIU is preferred, but the CATV line can be split and continued.

Run the shortest distance possible, but avoid aisles and areas used for storage. You may need to run around the

eaves, or even clip cable along the inside of the roof and come down a pillar.

The attic is usually accessed from outside by running the cable up the corner of an exterior wall. Before you drill,

inspect the attic and check for any obstructions or clutter. Running cable up from the crawlspace or basement is

a better and far less obtrusive method of getting to the attic. There may be an existing chase, but you may need

to ‘fish’ the cable up and alongside plumb-

ing or HVAC ducting. See page 9.7 for

instructions.

If entering from the outside, drill your entry

hole at the roofline or slightly above it at

a slightly upward angle. Use a feed-thru

bushing to prep the hole (see page 9.4 for

details). Feed the cable through the bushing

and over to the drop; take more cable than

you’ll need. Remember to seal the bushing

after the cable is pulled into place.
