The best time to plan the installation for wiring a doorbell is when the walls and ceilings are still open during new construction or remodeling. If you want to install a doorbell for the first time in a finished house, you may want to consider a wireless doorbell so you don't have to cut into the walls to do the wiring.
Wiring a doorbell in a new home is very easy. Doorbell wiring is low voltage wiring which uses around 12-volts. The wire size is about 18-guage wire. It's actually called doorbell wire, so you can't go wrong with that.
18 Volt Power Tools
You will need to run the wire from each doorbell back to the doorbell transformer. Doorbell wiring requires a transformer that connects to a 120-volt circuit. It reduces the electric voltage to about 12-volts.
Be sure to turn off the electricity before you wire the doorbell transformer to the house power. Turn off the breaker and tell other family members what you are doing.
The transformer will have a hot screw and a neutral screw. The black wire from the house power will connect to the hot screw and the white wire will connect to the neutral screw. This will give the doorbell transformer power. There will be one hot wire and one neutral wire that runs from the transformer to the chime box.
The doorbell wiring will use two hot lines that run from the chime box to the doorbell. If the doorbell is controlling two locations, then it will most likely have two different chimes so you know which door to answer. The cable will connect to the transformer with two hot screws for each doorbell. The cable will also attach to each doorbell with these two hot cables. When the doorbell button is pushed, the circuit will complete the electrical current and the doorbell will chime.
Once all the wires are attached, you can secure the doorbell, chime box, and transformer. Turn on the house power and test the doorbell.
To replace an existing doorbell, you will only need to detach the old doorbells and replace them with the newer bells. If you want a different chime, then you will need to replace the chime box by removing the old wiring and connecting the newer wiring.
In some cases, you will need to replace the transformer for a new doorbell and chime if it needs different voltage to function properly. This can be done by first, disconnecting the house power, then replacing the transformer with the new transformer. After that you can turn the power back on and test the new doorbell system.
