Your two are more than likely wired in parallel due to the one transformer being 16 Volts and your multimeter readings being 12 to 20 volts. You’d be better off taking your reading at each transformer after isolating each one to get more accuracy as 12 to 20 V is a big difference.

Can you have more than one doorbell transformer?

A: 2 Video Doorbell Pros can certainly operate on 1 transformer. As you mentioned the age of the existing doorbell, a transformer this old will likely need to be replaced with a newer transformer and a slightly more powerful one to operate both Pros and the existing chime kit.

Do you need a transformer for each doorbell?

Is a transformer required for all doorbells? Yes. Doorbells are low-voltage applications and they will not work without a transformer.

How do you wire a 2 doorbell transformer?

Quote from the video:
Quote from Youtube video: The blue wire is from the button. Actually it's going to the button and the other blue ones coming down they're connecting the doorbell the orange ones going back to the transformer.

Where are most doorbell transformers located?

Doorbell transformers are usually tucked away along an exterior wall in your garage, basement, or attic. It will be in the general vicinity of your doorbell(s), typically close to the ceiling of that room. It will be attached to the side of a wall-mounted electrical junction box.

What transformer is needed for 2 ring doorbells?

If you don’t have an existing doorbell, it’s possible to connect a Ring Doorbell 2 directly to a low voltage 8-24V AC transformer (40V maximum) at 50/60Hz.

What size transformer do I need for a 2 doorbell?

It looks like they want ≥10VA at 16-24VAC per doorbell, so at least 20VA would be required for 2 of them. More than 20VA is fine, of course.

Where is the hidden doorbell transformer?

Quote from the video:
Quote from Youtube video: The most common place is in a utility room the most likely place for the transformer is going to be in a utility room right that's where I would hunt.

Is my doorbell transformer in the chime box?

Where is the Doorbell Transformer? Many builders will install the doorbell transformer near the main electrical panel or inside the doorbell’s chime or bell enclosure for easy access.

How do I know if my doorbell transformer is AC or DC?

How can I identify if a transformer is AC or DC? A transformer type of current, AC or DC, is given by the symbol located between the voltage and the amperage of the transformer. The bellow image is from an 8V ~ 1A AC ( alternative ) transformer, where the ” ~ ” symbol is between 8V and 1A.

Are all doorbell transformers AC?

Older doorbells were supplied by a 6 or 8 volt transformers. Newer doorbells operate at 12 or 14 volts AC. Modern door chimes operate at 16 volts AC. Replacement transformers are available with single-voltage secondaries, center-tapped, two voltage secondaries or multitapped, multiple-voltage secondaries.

Do transformers put out AC or DC?


A transformer is a device which step-up or step-down the level of AC current or voltage without changing the primary (i.e. input source) frequency. Transformer only works on AC and can’t be operated on DC i.e. it has been designed to be operated only and only on alternating current and voltage.

How do you identify a transformer?

Quote from the video:
Quote from Youtube video: And blue are exactly colors for mains voltage so violently drive and blue is always neutral.

How do you identify an unknown transformer?

Quote from the video:
Quote from Youtube video: So in this case low-resistance will mean its secondary coil and higher resistance will mean its primary coil as you see this should be primary coil.

What is the name of the orange and white transformer?

Transformers: Generation 1

Motto “Unchecked power is the true path to divinity.”
Alternate Modes F-15 Jet Fighter, Cybertronian Jet
Series Transformers: Generation 1 Transformers: Universe Transformers: Titanium

How do you find the primary and secondary transformers?

Quote from the video:
Quote from Youtube video: This for example has three wires on one side and another 3 wires of the same size at the other side so for this kind of transformer we need another method.

What is the difference between primary and secondary transformer?

Generally, the primary winding of a transformer is connected to the input voltage supply and converts or transforms the electrical power into a magnetic field. While the job of the secondary winding is to convert this alternating magnetic field into electrical power producing the required output voltage as shown.

Can you reverse the primary and secondary on a transformer?

Usually, there is not any problem with reversing the primary and secondary of a power transformer, as long as the transformer power rating, the product of RMS volts*amps, is not exceeded.
