If you’re considering installing a second Ring doorbell at your home or business, you might be wondering how to power it. One option is to use a transformer, but can you install two Ring Doorbells on one transformer? The answer is yes, but there are a few things to consider before doing so. 

We’ll explore the potential benefits and drawbacks of using one transformer to power two Ring Doorbells and provide a step-by-step guide on how to do it. 

By the end of this article, you’ll better understand whether installing two Ring Doorbells on one transformer is a viable option for you and, if so, how to do it.

What Is A Transformer, And Why Do You Need It For A Ring Doorbell?

A transformer is a device that changes the voltage of an alternating current (AC) electrical supply. In the case of a ring doorbell, the transformer is used to step down the high voltage of the AC supply, usually around 120 volts, to the lower voltage needed to power the doorbell, typically 16 volts or 24 volts.

The transformer is essential to the doorbell system because it helps ensure the doorbell receives the correct power. Using the wrong transformer or a transformer with the incorrect wattage can result in insufficient power to the doorbell, causing it to function improperly or not at all. 

It’s essential to use the correct transformer for your doorbell, as specified by the manufacturer, to ensure proper operation and avoid damaging the doorbell or the transformer.

Can You Install Two Ring Doorbells On One Transformer?

The short answer is: yes, it is possible to install two ring doorbells on one transformer. However, a few factors must be considered before attempting to do so. The size of the transformer, the wattage of the transformer, the wattage of the doorbells, and the distance between the transformer and the doorbells can all affect whether or not it is feasible to use one transformer to power two doorbells. We’ll delve into these factors in more detail in the next section.

Requirements To Consider

There are a few requirements to consider when deciding whether or not to install two Ring Doorbells on one transformer. These include:

  1. The size of the transformer: The size of the transformer is essential because it determines how much power it can supply. If the transformer is too small, it may not be able to provide enough power to both doorbells.
  2. The wattage of the transformer: The transformer’s wattage is a measure of how much power it can supply. It’s essential to use a transformer with sufficient wattage to power both doorbells.
  3. The wattage of the ring doorbells: The wattage of the doorbells is crucial because it determines how much power they require to operate. It’s essential to add up the wattage of both doorbells to ensure that the transformer can supply the necessary power.
  4. The distance between the transformer and the doorbells: The distance between the transformer and the doorbells is crucial because it affects the amount of power lost over the distance. The longer the distance, the more energy is lost. It’s critical to ensure the transformer can supply enough power to the doorbells even after accounting for power loss due to distance.

What Is The Best Transformer For Ring Doorbell 2?

The best transformer for the Ring Doorbell 2 is the Hardwired Transformer for Ring Wired Video Doorbells. This transformer is specifically designed for use with the Ring Doorbell 2 and can provide the necessary power to ensure the proper operation of the doorbell. 

It is a 16VAC, 30VA transformer with a built-in surge protector to protect against power surges. To use this transformer, you’ll need to hardwire it into your electrical system. It is essential to follow the manufacturer-provided installation instructions carefully to ensure safe and proper installation.

How to Install Two Ring Doorbells On One Transformer

Installing two ring doorbells on one transformer is a relatively simple process, but following the steps carefully is essential to ensure proper installation and operation. Here’s a step-by-step guide on how to do it:

  1. Determine the size and wattage of the transformer.

    Before you start, you’ll need to determine the size and wattage of the transformer you will use. The size of the transformer is essential because it determines how much power it can supply. The transformer’s wattage measures how much power it can provide. It’s necessary to use a transformer with sufficient wattage to power both doorbells.

  2. Calculate the total wattage needed for both doorbells.

    Next, you’ll need to calculate the total wattage required by both doorbells. The wattage of the doorbells is crucial because it determines how much power they require to operate. Add up the wattage of both doorbells to ensure that the transformer can supply the necessary power.

  3. Install the transformer and connect it to the doorbells.

    Once you have determined the size and wattage of the transformer and calculated the total wattage needed for both doorbells, you can proceed with the installation. Follow the hardwiring installation instructions provided here carefully to ensure safe and proper installation.

  4. Test the doorbells to ensure they are working correctly.

    After installing the transformer and connecting it to the doorbells, you must test them to ensure they are working correctly. This will help you identify any installation issues and ensure that the doorbells are functioning as expected.

Tips For Successful Installation

To ensure a successful installation of two Ring doorbells on one transformer, there are a few tips to keep in mind:

  1. Use a transformer with a wattage higher than the total wattage needed for both doorbells: It’s a good idea to use a transformer with a wattage higher than the total wattage required by both doorbells. This will ensure that the transformer has sufficient power to operate both doorbells, even if one doorbell requires more power than the other.
  2. Use a transformer with a built-in surge protector: To protect against power surges, it’s a good idea to use a transformer with a built-in surge protector. This will ensure that the doorbells and the transformer are protected against sudden spikes in power that could potentially damage the system.
  3. Follow the installation instructions provided by the manufacturer carefully: It’s essential to follow the installation instructions provided by the manufacturer carefully to ensure safe and proper installation. This will help prevent accidents or injuries and ensure that the doorbells are installed correctly.

Conclusion

It is possible to install two Ring doorbells on one transformer, but there are a few things to consider before doing so. The size of the transformer, the wattage of the transformer, the wattage of the doorbells, and the distance between the transformer and the doorbells are all factors that can affect whether or not it is feasible to use one transformer to power two doorbells. 

Suppose you decide to install two Ring doorbells on one transformer. In that case, it’s essential to use a transformer with a wattage higher than the total wattage needed for both doorbells, use a transformer with a built-in surge protector to protect against power surges, and follow the installation instructions provided by the manufacturer carefully. 

If you need clarification on the installation process, consulting with a professional is always a good idea.
