I thought Ring doorbells were battery powered? Don't the TV ads say no wiring needed? And they work using WiFi?
So sad and true. If you go shopping for a new doorbell, you are directed to a wall of wireless options.
None of which will work 9 months in the future, either due to dead batteries, wet RF electronics and/or just plain old crappy design.

The original transformer system lasted for 40 years, with 99.999999999% operational reliability.

Well I now know that the Doorbell Transformers in 2,000 and Up Output 24 Volts and are Rated 20 V/A.

And Doorbell Transformers in the 70' 80's and 90's Output 8. Volts to 16 Volts.
But You Say they are also Rated 20 V/A.

How can the Doorbell Transformer be Rated 20 V/A back then?
I Understand the Voltage Output was Less because it just had to Ding.
But why was it still Rated 20 V/A?

Because the an electromechanical doorbell hasn’t changed in the past 60-years. They sound the same now as they did then. An industry standard. Also, an electromechanical doorbell takes a lot more power to operate than a Ring Doorbell / camera.

Your question is like saying
My current toilet and hot water heater recommend 45 to 60 psi - how could residential water pressure also be 45 to 60psi back in the 1960s?

Or my house was built in the 1960s and the opening between cabinets is 30” for my stove, How could current stoves still be 30” wide? Or god knows what else hasn’t changed since your house was built.

Get over it, either install the doorbell or return the doorbell or ask someone with more confidence in their skills to install the doorbell for you.

I’m guessing he either:
- needs some solid evidence to buy a modern transformer before his wife approves
- he is afraid some magical electrical phenomenon will damage the Ring Doorbell that he paid for and is rotting in the box. That is, He would not benefit from of the uninstalled doorbell than damage the doorbell and not get any use out of his expense.
Now I have to wonder if he is trying to find an excuse not to install the cameraDoorbell because he doesn’t want to see what is going on in front of his house or he doesn’t want his wife to see what’s going on in front of his house.

As you know I was thinking about Installing a Ring Doorbell.
I just have a Standard Doorbell that is Analog and does not Play a Melody.

I know I do not have to install the DIODE that comes with the Ring Doorbell and because my House was Built in the 2,000s I know the Doorbell Transformer will Supply the Right Voltage.

But I was Looking at some Videos on YouTube and they Say the Doorbell Transformer Must Supply 40 Volt / Amps for the Ring Doorbell to be Hard Wired in.

I thought most Analog Doorbell Transformers Output 20 Volt / Amps?
Or does this not really Matter?

A Ring Pro needs 30VA and a standard Ring or Ring2 need 20VA. How does some video on YouTube carry more credibility than the Ring instruction manual? Why are you afraid to install the dang, stone-simple doorbell? This thread has been lingering for a long time. My neighbor's 14-year old daughter installed their Ring - it works and the house didn't burn down.

Like I Say I was thinking about getting The Ring Doorbell.
And I wanted to know how all of the Ratings worked.

And I know it is just 2. Wires and no big thing to do.
But I did not want to Charge the Battery take out my Old Doorbell Switch and Install The Ring Doorbell.

Just to See nothing worked and have to put my Old Doorbell Switch back.

I did not put this Post up thinking it would make People Mad.

Thanks for the help.
