Does a Door Bell or Chime need a ground.

by Patrick

My house was built in 1926. Instead of a normal door bell I have a buzzer. I took it apart wanting to install a new door bell. I noticed that the buzzer has only two wires. I am guessing it does not have a ground wire. Do I really need a ground wire or can I get by without one.

Patrick,

Typically a doorbell doesn't require a ground. It is a low voltage circuit and doesn't come with a ground. Especially a circuit of that age. Grounds were not as big of a safety issue back then as they are today.
Here's a great link that shows a typical door bell / chime wiring circuit

Hope this helps and Thanks for visiting.
