Running wire through a wall is a complex operation. If you aren't familiar with construction or what lies behind sheetrock, you might want to hire an experienced electrician. Is there an attic or a crawl space where you can run wires? Is this an exterior wall? Is there any plumbing or existing wiring in the wall where you plan to run the wire?
Things You'll Need
- Electrician's fish tape or stiff steel wire
- Straightened out hangers with a hook on the end (for short applications)
- Electrical tape
- Drill (electric or 18- to 24-volt battery)
- Spade or auger bits (three-eighths inch to 1 inch)
- Extra long drill bits
- Electrical boxes or low-voltage rings
- Wire or cable
- Keyhole saw or a sharp sheetrock knife
- Straight edge at least 6 inches in length
- Stud finder
- Cover plates, receptacles and connectors as required
- Dust mask, disposable coveralls and a head-mounted flashlight, if working in an attic
- A helper, to keep you from running back and forth.
- Heavy duty twine
Verify that there are no plumbing pipes or wires in the area where you will be cutting into the wall.
Using the template provided with the electrical box or the low voltage frame, mark the hole to be cut.
Double check with a stud sensor to make sure there is no stud in the way of the hole to be cut.
Cut the hole.
Leave an assistant at the hole in the wall while you go into the attic.
Drill a hole right above your desired location in the 2X4 header at the top of the wall from the attic. If you need to get past fire blocking further down then use a long drill bit to drill through that also.
Run a fish tape through the holes just drilled. Alternatively, long drill bits often have a hole next to the tip that can be used to pull a wire or string back with the drill bit.
Have your assistant pull the end of the fish tape out of the wall and attach the wire.
Your assistant should tape over the wire at the attachment point to keep it from coming loose and to smooth out the leading edge of the wire that might otherwise snag or get caught in the hole or the wall.
Pull on the fish tape from the attic as your partner feeds the wire or cable. Pull enough wire to reach the desired location at the other end of the cable.
Run the fish tape down at the other end of the wire run like was done above.
Connect a heavy twine or baling wire to the end of the fish tape and pull that into the wall where your wire or cable will go.
Connect the heavy twine or baling wire to the cable you are installing.
Pull on the lower end of the twine or baling wire as you feed the cable into the wall.
You should how have a cable hanging out of the wall at least 8 inches at either end. Make whatever connections are needed for your purpose.
