door chime low voltage converter


I took this low voltage converter out a few years ago and don't remember how it was wired. Left side goes inside the panel, right side is the wiring out. What confuses me is that there are two, what appears like awg 18, stranded wires that are supposed to be wired inside the panel but I am unsure if they should just both be spliced to a hot wire going to a breaker. Also how about the ground and
the neutral? Are they not needed because of the low voltage?

This inquiry is only about the converter, not the rest of the chime wiring.

Thanks in advance.

Assuming its a 120VAC transformer, one wire goes to neutral, the other to a hot wire. The outside of the transformer would normally be grounded when threaded into a metal junction box or your panel.

correct assumption. thanks. both inside-the-panel wires look the same. does it matter which goes to hot and which goes to neutral (guided by the colors of the outside wires (red and white)?

what if there is no metal JB? by "panel", do you mean the main electrical panel that this thing is attached to?

With an AC transformer like this it won't matter which wires goes to hot/neutral.

If you're mounting it to an existing metal electrical panel, the metal panel enclosure should already be grounded. Then, mechanically fastening the transformer will take care of grounding it too.

by the way be sure that your panel is earthed.

Make sure you hook up to the correct side.....

And...for reference, it's not a converter, it's typically called a low voltage transformer or door bell transformer. The typical transformer is 16 Vac....just be aware that a typical HVAC transformer looks exactly the same but is 24Vac....

Just out of curiosity....why hardwired now instead of wireless? Even though I could easily run the wire in my house right now since everything is opened up....I prefer wireless. We like the flexibility of putting the chimes where we want. Seeing how everyone is afraid to come to my door anyway, the door bell gets rarely used.
