Try the attic: Doorbell transformers are sometimes installed on an existing junction box in the attic of a ranch or a house with an attached garage near the front door. It may be in the closet: The doorbell transformer may be attached to the wall opposite the closet door. Move a few coats around and it might be there.

Can a doorbell transformer be in an electrical box?

The National Electrical Code (NEC 725.136A) specifically excludes any low voltage wiring from being installed in an electric panel, raceway, or box used for high voltage (120/240V) circuits.

Where do you hide a doorbell transformer?

When it comes to hiding your doorbell transformer, it needs to be in open air and cannot be enclosed. One example of where to hide your doorbell transformer, is off the attic light socket. Alternatively, you can hide it in a closet, behind and above the sliding door, or in your basement.
