Doorbells are typically wired with 18 gauge wire, also referred to as "bell" wire. Terminals on the buzzer/bell are commonly labeled "F", "R", and "C". "C" stands for common and should be tied to one of screw terminals coming out of the transformer. "F" stands from front and is used for the front door bell.

What is the standard voltage for a doorbell?

The doorbell switch has two terminals that are wired to the doorbell transformer located in the house. The transformer is a metal box with two terminals connected to the doorbell wires. It takes the standard electrical voltage in your home, in most cases 110 to 120 volts, and lowers it to about 10 to 24 volts.

Do doorbells run on AC or DC?

A doorbell transformer steps down the 120 or 240-volt AC electrical power to a lower voltage, typically 6 to 24 volts. The transformer's other terminal connects to one of three terminals on the signaling device. Another terminal is connected to a wire that travels to the other terminal on the button.

What power supply does a ring doorbell need?

Power & Voltage Requirements It requires a compatible doorbell, a Ring plug-in adapter, or a transformer rated for 16-24V AC at 50 or 60 Hz, with a maximum power of 40VA. You can also use a Ring DC transformer or a power supply. Halogen or garden lighting transformers will not work and can damage your doorbell.

Why do I have 6 wires for my doorbell?
