Find out how to Wire A Doorbell

Doorbells are relatively safe to put in because they use low voltage power instead of the complete 110 or 120 volts of most circuits. That means you must hook it up a small transformer that brings the normal house circuit right down to between 12 and 16 volts, which is plenty to make the bell ring. As with all wiring, it’s easiest to put in before you finish the walls, but it’s possible to run the cable through an attic or crawl space as well.

Things You may Need
Doorbell system
18-gauge electric wire
Wire strippers
Screw driver
Wire nuts

Turn off the electricity to your own home, as you’ll be working with live wires.

Discover a junction box that holds one in all your existing home circuits. You might find one in the attic, crawl space or behind a cover on one in all your walls. You’ll need this junction later to connect the transformer.

The low voltage transformer that came with your doorbell system has black and white leads coming out of it. Twist the black wire onto the black wire out of your circuit using a wire nut. Do the identical with the white wire.

Run the 18-gauge wire through your attic or crawl space from the doorbell to the junction box.

The low-voltage transformer that came along with your doorbell system has a hot screw and a neutral screw (labeled as such). From the 18-gauge cable you just ran, connect the black wire to the recent screw, and the white wire to the neutral screw.

Choose a spot for the bell portion of the system somewhere along the path of the the wire you ran. It doesn’t matter where, just make sure that you can hear the noise of the bell from wherever it’s.

Cut the 18-gauge wire on the spot you chose for the bell.

Tips & Warnings
Some transformers could have a plug that may be plugged straight into the wall. In that case, just plug it right into a socket instead of splicing it together at a junction box.
