Hi, I am a DIYer, have some electrical experience from flipping houses, and would like to think I am pretty good at picking things up. But I do have a question, or really a clarification that I need if I am thinking right on this project.

We are adding a Nest Hello doorbell and the current transformer is only 10v 5va. So we need to upgrade it to a 16v 30va (Hampton Bay 16VAC/30VA Transformer Compatible with All Video Door Bells-HB-130-03 - The Home Depot).

The old/current transformer has only two black wires that I can see. And if I am not mistaken, one is tied into a hot circuit breaker and one into the ground bar. However, the new transformer has 3 wires. I understand the black one should go to the same breaker and the ground should go on the ground bar (left side). The question: if it is correct that the new white wire should go I think it is the neutral bar on the right side in the picture.

I'd appreciate your alls expertise!

I will attach some pictures for a better idea and a drawing to see past the convoluted wiring.

Yes. The white wire should go to the neutral bar. If this is the main panel the neutral and ground bar should be connected so you could go to the bar with the ground wires.

Thank you joed!
