Why do you think you did not need the doorbell voltage and amp ratings? You have to match the transformer voltage to the doorbell voltage rating. Plus, the transformer amp rating must exceed the doorbell requirement.I did not need the Voltage and Amps for the Doorbells.
First, it appears that you are confused about ampere ratings. Amp ratings of a power SOURCE are the maximum amperes that it can supply. A 120VAC 15A does NOT supply 15A to the load. It can supply UP TO 15A, but the LOAD ampere requirement is what determines the amps in a circuit. Approximately, a 40W bulb pulls 330mA; not 15A.I am not Replacing any Doorbells I just wanted to know.
Because most Basic House Circuits are 120 Volts 15 Amps.
Now this would be to High for Say a Ring Doorbell.
Ring Doorbells are Rated 16 Volts 20 Amps.
This is why the Doorbell Circuit has a Transformer to Supply the Right Voltage and Amps to the Doorbell.
But over the Years things change with Power Needs and so on.
So if you did come across a House Built in the 1990's and Before what would the Doorbell Transformer Voltage and Amps Output Be?
And if the House was Built in the 2,000's what would the Doorbell Transformer Voltage and Amps Output Be?
