* Wouldn't worry about where it is connected...It's DC ...I've used a
lot stronger DC voltage while being underwater...no worries...I'v
replaced my doorbell hot outside in the rain... Hell i'd sit in my hot
tub touching both wires at the same time.. Been a rig welder of thirty
years welding with DC out on a pipeline in the rain... a doorbell???
sheesh...just wire it... Jim

Why would it be DC instead of AC? *Hardwired doorbells usually have a
step-down transformer that changes higher voltage AC to low voltage AC,
but there is no rectifier that changes the AC to DC.

No Jay... to convert AC to DC would require a rectifier...to convert DC
to AC requires a converter... Jim

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.- Hide quoted text -

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.
