Materials You'll Need
- Telephone wall jack
- Screwdriver
- Wire strippers
- Electrical tape
- Pencil
Steps to Install a Telephone Wall Jack
- Turn off the power to the circuit. This is important for safety. Find the circuit breaker that controls the power to the room where you're installing the jack and turn it off.
- Locate the existing telephone wire. This is usually a pair of wires running through the wall. You can find it by removing the cover plate from an existing phone jack or by using a tone generator.
- Strip the insulation from the wires. Use the wire strippers to remove about 1/2 inch of insulation from the ends of the wires.
- Connect the wires to the terminals on the phone jack. The terminals will be labeled "L" for line and "T" for telephone. The order doesn't matter, so connect the wires to whichever terminals are most convenient.
- Secure the phone jack to the wall. Use the screwdriver to drive the screws that came with the phone jack into the wall.
- Turn the power back on to the circuit. Once the phone jack is installed, you can turn the power back on to the circuit.
- Test the phone jack. Plug a phone into the jack and make a call to test it.
Tips for Installing a Telephone Wall Jack
- If you're not confident in your ability to install a phone jack, you can hire an electrician to do it for you.
- If you're installing a phone jack in a new location, you may need to drill a hole in the wall to run the wires.
- If you're replacing an existing phone jack, you can simply disconnect the old jack and connect the new one in its place.
