Important:
The name of Video Doorbell Pro has changed to Wired Doorbell Plus. All the great features of your Video Doorbell Pro are still the same. If you purchased a Wired Doorbell Plus, you can use instructions for Video Doorbell Pro.

Learn how to estimate the gauge of a wire and identify the correct wire gauge to use when wiring up the Ring Video Doorbell Pro.

If the wire is too large, it can be hard to manipulate. If it's too small, it may not be adequate to transmit power.

Wire Gauge Wire Comparison

18-gauge wire (ideal)

18-gauge wire is the ideal gauge to use with Ring Video Doorbells. It provides the proper amount of resistance and is very easy to work with and makes wiring simple.

18-gauge wire is approximately the width of a standard metal thumbtack.

16-gauge wire (usable)

While not the ideal gauge, you can use a 16-gauge wire with Ring Video Doorbells. It's easy to work with and won't cause much resistance, providing adequate power.

16-gauge wire is thick enough to cover the ridges on the terminal screw on the back of your Video Doorbell Pro.

20-gauge wire (usable)

While also not the ideal gauge, you can use a 20-gauge wire with your Ring Video Doorbell Pro. It's easy to work with and won't cause much resistance, providing adequate power. 

20-gauge wire is the same size as the slots in the terminal screws on the back of your Video Doorbell Pro.

22-gauge wire (unusable)

A 22-gauge wire is a bit on the thin side and may not provide all the power that the Ring Video Doorbell Pro needs.

24-gauge wire (unusable)

If you're down to a 24-gauge wire, you'll find it's inadequate for wiring and powering up a Video Doorbell Pro. If you have wire this thin, you may be able to use the Ring Plug-in Adapter.

24-gauge wire is the same width as the thin side of a bobby pin.
