Hmmm,
Typically door bell works off 24V AC, try to find the transformer
feeding the door bell. Mine is mounted on the side of breaker panel box.
Even if you don't turn it off, I doubt 24V AC will kill you if touched.

Mine was mounted up in the attic in a random spot. Spotted it when I was

Could be on any breaker; no official rule for where to put a doorbell.

Probably several ways to skin this cat. One would be to put a voltmeter
on the transformer (that's the thing that supplies low voltage
power--typically 16-24 volts--to the actual doorbell) and flip breakers
until it goes to zero volts (assuming the transformer works). Probably
the safest way; that secondary (low-voltage) side of the transformer
isn't going to hurt you if you get shocked by it.

Welllll, that's true in *theory*. But probably lots of folks have been
hurt (or even killed) when theoretically impossible.

Just to be clear, there are two issues he

1. Whether or not you can get shocked by just touching one wire of a
circuit.
2. Low voltage vs. high voltage.

First issue: yes, in theory if you touch only the hot wire of a circuit,
you won't get shocked. (Works for birds sitting on powerline wires, for
instance). Problem is there are other sneaky way of the circuit
completing itself, like through damp ground, your shoes and your feet.
So the best policy is to never touch *any* wires (energized ones, that is).

Second issue: As I said, doorbells operate on low voltage (somewhere in
the range of 12 to 24 volts AC). Getting shocked by such low voltages is
a lot safer than high voltage (like the 120 volts in your household
wiring). While it is theoretically possible to get electrocuted from
even a low-voltage shock, it's unlikely. So it's safer messing around
with low-voltage wiring that may be live than high-voltage wiring. Still
not recommended (see best policy above).

Sweaty wet hands may have done it, or if you have a little cut you have
been ignoring, 12 volts will remind you. Normally I can put my hands
across a car battery and not feel a thing. When sweating that adds salt
to the moisture and makes a big difference. Plain water isn't really a
great conductor, but the higher the voltage the more dangerous it
becomes. You can actually spill water on a CPU board while it's on and
although it may stop working, it will most likely work again after it's dry.

I'd just wire it hot, since it is likely only 16v. But if that concept
bothers you, you need to figure out where the transformer is. When I was
a kid and we built houses the cave-man way, we always put the
transformer near the service panel, to make future swapouts easy. In
this place I am now, I found the damn thing in the attic, hung off the
J-box that feeds the bathroom and hall ceiling light. Turn that breaker
off, and doorbell is off.

When they make me benign dictator of the planet, I am going to require
that GCs, electricians, plumbers, etc, map out whatever they do, and
leave a legible rot-resistant diagram in a water-tight container screwed
to the wall next to the service panel. Breaker maps, path of wiring and
plumbing runs, location of any item with a lifespan less than the house
itself.

If you do the work in the daytime, you can switch off all of the individual
circuit breakers and leave them off, and then switch off the main breaker.
That will cut off the power to everything in the house, and you can do the
work using daylight to see what you are doing (or use a flashlight, if
needed). When turning the power back on, do the reverse -- switch the main
breaker back on first while all of the individual breakers are off, then
switch each of the individual breakers back on one at a time until they are
all switched back on.

Or, you can do what others have suggested -- just do it while the power is
still on. If you are nervous about doing that, just do it carefully, one
wire at a time. You can even use pliers, wire cutters, and/or a screw
driver that have insulated handles so your hands are not touching metal when
doing the work. It's a low voltage circuit, so it should be no problem even
if you do accidentally touch something. Plus, the doorbell switch itself is
a switch that should keep any power from going to the actual bell unless the
doorbell switch is pressed (assuming it is wired correctly).

Why would it be DC instead of AC? Hardwired doorbells usually have a

there is no rectifier that changes the AC to DC.

I think that's what I said -- that there is no rectifier in the doorbell
system to change the house AC to DC for the doorbell. So, the doorbell
operates on AC, not DC.

You wrote that the OP shouldn't worry because "It's DC". I was just
pointing out that it is not DC that is powering the doorbell.

Why not use common sense. Turn off half the breakers and see if the
old doorbell still works. If it does not, then replace it and turn
those breakers on. If the doorbell still works, turn those 1/2
breakers on and turn the other 1/2 off. That should stop the doorbell
from working if it is on a breaker. Then replace the bell.

It is only 24 V at most on the secondary of the transformer if it is
anywhere in the USA and will not kill you. The biggest problem is
that if you get a shock you may make a sudden move and hurt your hand
on something. But, to get a shock you have to have both wires
energized, and that only happens when someone pushes the doorbell
button, so keep eeryone who does not like you from pushing the
doorbell pushbutton.

Doorbells operate on AC, not DC.

And regarding the further conversation regarding conversion, etc., the
only conversion going on is the stepping-down to low voltage AC by the
transformer. (AC-- AC) No rectifiers used here.

Yes, 24 volts is less likely to electrocute you than 120 volts

and the secondary winding of the transformer is isolated with respect to ground

but would it really take that much effort to just shut the breaker off while you replace the doorbell components?

Yes, 24 volts is less likely to electrocute you than 120 volts

and if you're just replacing the button the only thing a short can do is
ring the bell.

and the secondary winding of the transformer is isolated with respect to
ground

and has a non-replacable fuse in it, so shorting it may mean you need a
new transformer.

but would it really take that much effort to just shut the breaker off
while you replace the doorbell components?

Especially if you've previously identified the breakers, so you know
which to shut off.

Jumper the switch and then flip breakers until the noise stops.

Am about to replace hideous doorbell. AFAIK, I just have to unscrew
tthe old one and attach the new one to the wires.
BUT - how do I know which "breaker" as they used to call them,
controls the doorbell? I looked in my switch box, where I have
everything labeled, but did not see "doorbell". It rings in the
kitchen. Anybody hazard a guess where it might be connected?

Jumper the switch and then flip breakers until the noise stops.


Most doorbells I have worked on, that won't work. Energize the circuit,
and it rings once. The hammer in the doorbell doesn't retract until the
current stops. It would work for a simple buzzer, though.

If you have that kind, you could turn breakers off one at a time until
you hear the "dong".

Or you could connect a buzzer for this purpose.

BTW, A neighbor had a problem in that she couldn't tell the difference
between "ding dong" for the front door and "ding" for the back door
(or the "ding ding" that happens with over-excited button pushers). I
added a buzzer across the front door solenoid. The only buzzer I had
at the time was a DC pulsating buzzer. After adding the rectifier and
capacitor, she had a unique doorbell. It sounds the same for the back
door, but for the front you hear "ding dong" along with a
non-confusable "BEEP-BEEP-beep-beep-bip-bip". That house has been sold
twice since then and that thing is still there.
