Doorbell wires are usually safe to touch, but sometimes they can fail and shock you. When it fails, diagnosing and repairing the problem is usually simple. Most systems comprise only three major components and the wiring that connects them. Let’s find out Can Doorbell Wires Shock You? and how we can install a new one without getting shocked. 

Is it okay to touch the doorbell wires?

 Doorbells are usually safe to touch. Because the circuit is low-voltage, the Doorbell cannot shock you. Home electrical services are linked with 120 volts of electricity, which makes them extremely dangerous to touch. But the doorbells work differently. Doorbells do not operate on 120 volts, so they are not hazardous to touch. 

They use a transformer to reduce the voltage. The transformer can sometimes fail, and doorbell wires transmit dangerous electricity. But this only happens sometimes. Doorbells are usually safe to touch. However, only touch the wiring once you have tested the strength of the current at the pushbutton or bell. 

How To Install New Doorbell?

If your Doorbell is worn out or shocks you, it’s time to change before you face a big loss. Installing a new bell is easier than you think. It’s a project that DIYers can take on with their comfort. A variety of doorbell and chime boxes are available in the market. You can choose the bell of your choice. They are simple to install using the existing wiring. Let’s find out how you can install your Doorbell in an hour.

Steps To Install A Doorbell

Locate the Main Electrical Box.

Locate the main electrical box and turn off the breaker for the Doorbell. Remove the screws that hold your Doorbell to your house using a flat-head screwdriver.

 Check that the power is turned off.

 Turn the power off before removing the doorbell unit from the house. Place the probes of a voltage meter against each terminal screw on the back of the unit.

Remove the Wires

To remove the wires, unscrew each terminal screw. Because the wires are interchangeable, you do not worry about which wire goes to which terminal. 

Change out the Doorbell Button

Now loosen the terminal screws on the back of the new doorbell unit. Bend and wrap each wire around a terminal screw with needle-nose screwdrivers. Screw the screws in place. Place the doorbell flat against your house and hold it there. Use the screws to secure the unit. To learn more about the Fluke vs Klein multimeters, click here.

 Locate the Chime Box, flip the Breaker main electrical box, and turn the breaker for the Doorbell to the off position. Remove the chime unit’s cover, which is secured with screws. 

Disconnect and Test

Place a voltage meter probe against the terminal screws to ensure the power has been turned on. Before disconnecting, tape each wire and note which wire connects to which terminal. 

Loosen and detach

Disconnect the wires from the terminals by loosening the screws. Remove the screws that hold the chime base to the wall. Pull the unit away from the wall slowly.

Get the New Chime Box Ready for Installation

Remove the new chime box unit’s cover. Pull the wires through the chime base’s hole. Hold the unit to the wall to see if the new unit’s holes line up with the old chime wall holes. Now Set aside the chime unit and drill small pilot holes in the wall at each reference point.

Complete the Doorbell Chime Box Repair

Using the provided screws, attach the chime box to the wall. Unscrew each terminal screw. Using needle-nose pliers, bend and wrap the corresponding wire around each terminal. Fix the chime box cover to the bottom and turn on the main electrical box’s breaker.


If your doorbell shock, you should use a multimeter to check the wiring before installing a new bell. It is easy to install a doorbell using the above steps, but If you want to be sure about the power supply to your Doorbell, consult an electrician to inspect the transformer.

Purchasing a wireless doorbell is a safer option because they do not rely on the electricity in your home. Batteries power them and also require less keep-up.


Is it compulsory to turn off the power while installing a doorbell?

A transformer operates the doorbell and chimes from 120 volts. But you should take your time and always turn off the breaker when working with electricity. 

When do I need to consult an electrician to check the doorbell?

If you are unfamiliar with electrical wiring, you should avoid doing so also if it is powered directly from the main power supply. In that case, it becomes more complicated because the rules will vary from place to place – and you are in a more dangerous situation, so hiring a professional is a good idea.
