I need Electric Help... Any electricians out there?

You already said that, and if you could just answer my question or take a pic of that breaker we could confirm my theory. When the switch is off, there is no leak in current, so tripping when you flip the switch fits with what an AFCI is designed to do

[yos9694]

Are AFCI commonly used? Would they detect a ground fault like a GFCI?
ETA: Looks like they are not GFCI unless labeled as so.

Yeah and I found out the hard way not to install a separate gfci outlet on an afci protected line. If you want both protections get a combo breaker

AFCI will not work?
Fun fact: GFCI (Ground Fault Circuit Interrupter) does not use or need a ground to work.

Too many false positives.

Does anyone know how ConEd disconnects service? Do they ever shut the service before the meter?
Have a yeshiva dorm that has no power and the meters are blank. No reading with my NCV tester on the wires before the meter.

It's all remote these days IINM

With the use of smart meters? There should still be power going to the meter.

Update: all the bills were paid on time. ConEd says they see there's an issue and will come check it out.

This is a really old doorbell chime, I'm trying to replace, anyone familiar with how it works?

Does it go to a transformer somewhere?
This is standard wiring:

Not sure.
It comes in at 10v AC, does that make sense?

[CountValentine]

Not sure.

If it is old, yes. New transformers are 18-24V. The doorbell cameras need the higher voltage.
The wiring goes like this. Two conductor wire from each of the front and back door switches to the transformer.  Three conductor wire from chime to transformer. All connections done at transformer location.

Yup it's very old. Can I get a buzzer for 10v?
Having trouble finding one an Amazon


ETA
This one says 16v can I get by?

That is a standard chime. What happen to your current chime?
Also you need to test the voltage at the transformer.

It's an apartment building, I assume they have a central transformer.

[Yo ssi]

This may work better, says 8 - 16v

I would get the chime and if it doesn't work just return it.
If you want to test the voltage at the chime. Disconnect the T wire at the chime and the wire for either the front or back door. Put your meter across those two wires and have someone push and hold the doorbell (front or back).

Thank you! Ordered the 2nd one, I assume it's the better option.

I tested the voltage with the chime off, using the live and neutral (not sure if that's the proper terms here) from the image above. (it was 10v)
