Ok so if most common Doorbell Transformers will be 16 VAC this is what I want to know?

My TownHouse was Built 20 Years Ago and the Ring Video Doorbell was not Out then.

So because all of these TownHouses have a Standard Doorbell and the House was Built 20 Years Ago they would have used a 120 VAC 15 Amp Circuit.

So the Doorbell Transformer would Step Down the 120 VAC to like you Say 16 VAC.

So it the Doorbell Transformer Steps Down the 120 VAC to 16 VAC am I Right it will Step Up the Amps?

And it I am what is it Stepping the Amps Up to?

 

First, you’ll need to find the inputamps. It’s NOT 15A. That’s the maximum amps from the supply and not the input amp rating.
Common misconception.

Note: by input amps, I mean the amps drawn by the transformer.

 

The typical bell transformer is rated at ~30va, so at 16v the total Current Capacity would just under 2A.
Max.

 

Ok so if My Doorbell Transformer is going to be Putting Out 16 VAC 2. Amps how can I Replace My Doorbell Switch with the Ring Doorbell?

The Ring Doorbell is Rated 16 VAC 20 Amps.

The Ring Doorbell is Rated 16 VAC 20 Amps.

20 Amps!!!

Are you sure? An old 100Watt light bulb only needs 1A! Your car needs less than 10A to start! An electric stove runs on less than 20A!

The Ring Doorbell is Rated 16 VAC 20 Amps.

Not 20A, it is 20VA. Or, at 16vAC, about 1.25A. Also, it is rated as needing a MINIMUM of 16VAC and 24VAC is also fine. So just connect it. It will be fine. If it's not, your voltage is too low. My neighbor's 14-year-old daughter managed to install his new Ring doorbell in about a half hour. Why are you overthinking the installation of a bulletproof (idiot proof) product? Not implying the neighbor's daughter is an idiot - she's not.

 

The Ring Doorbell is Rated 16 VAC 20 Amps.

Are you installing a Bell tower for the whole town to hear!

 

I think I understand the Ratttings?

The Ring Doorbell is Rated 16 VAC at 20 VA..
So if I am Right VA is VoltAmp?

And to find the Current the Ring Doorbell will need I do this
16 Divided By 20 = 1.25 Amps.

Am I Right?

Am I Right?

Close... but 16 divided by 20 is 0.8, not 1.25. Ironically, the proper calculation is 20 divided by 16, which is 1.25A.

 

16 divided by 20 is .8. you mean 20/16
1.25a
Max.

 

So am I Right My Doorbell works on AC?

And the Doorbell is Connected to a Transformer to Step Down the Voltage from 120 to a Low Voltage?
And even if My Doorbell Transformer is Putting Out 2. Amps the Ring Doorbell only needs around 1. Amp to Run?

Do I have this Right now?

 

Not quite: The transformer does not 'Put out' any current until a load (door bell) is placed on it, and then it depends on what the doorbell requires in the way of current, if it is 1a, then only 1amp flows.

I do understand that the Doorbell Transformer Steps Down the 120 VAC to 16 VAC.

And I do Understand that the Doorbell will Take what ever Current it need to work.
But the Doorbell Transformer has to putout the Right Current?

 

Yes it has to be capable of providing the required load current.

It has to be capable of the required current... or more.

if you have two transformers, rated 10A and 15A, and your load is 8A, both transformers will work, because both can provide 8A or more!

 

This is what I am Saying in the Year 2,000 and On is most Doorbell Transformers Putting Out around 10 Amps or 15 Amps?

Again, the question is a little ambiguous.!
The average bell transformer is 30VA rated, so at 16vac it is Capable of supplying a maximum of 1.8amps to any load.
IOW, the load current of the device should demand no more than 1.8a or under..
Max.

Where are you getting 10A or 20A? I don’t think any doorbell transformers are rated for that many amps.

Your Ring doorbell requires 1.25 amps. Or 20VA. Any transformer that provided exactly 16VAC and at a minimum of 20VA will work.

But we don’t know what transformer you have. And you ask about most transformers. Most is so unspecific. Is it 3 of 4? 99 of 100?

I did something simple which you could have done. I went to home depot.com and searched for “doorbell transformers”. If you try that, how many 16VAC transformers for a doorbell are rated for 20VA or higher? Like 30VA? How many don’t meet those specifications? I noticed that there are transformers rated for 24VAC output. Those won’t work. So, how many transformers sold by Home Depot will work for you? How many won’t? Do “most” of them work?

 

Transformers are rated at volt*amps (VA). Look at your transformer carefully, IT DOES NOT SAY 20A! It says 20VA.

They expect you to be able to divide and figure out how many amps are max. See the SEVERAL explanations above.

 

I thought Ring doorbells were battery powered? Don't the TV ads say no wiring needed? And they work using WiFi?
