Wired Doorbell Transformers, Doorbell Wire, & Batteries

Wired doorbell transformers are electrical devices that step-down the high-voltage electricity in your home to a lower voltage compatible for wired door chimes and wired doorbell push buttons.

The small table below shows the different wired transformers we carry at 1800doorbell.com.  Although we do not offer the largest selection, we have the necessary bases covered when installing or replacing your wired chime.

We are often asked questions about using a wired doorbell in conjunction with a Ring.com or Hello Nest video doorbell.  We suggest you visit their support pages, but we do offer this tidbit.  Video doorbells tend to use more amperage than a standard wired door chime.   Coupling the video doorbell with your wired chime requires even more amperage and most doorbell transformers don’t have enough power.  We would recommend the DH910 for these purposes.

Doorbell transformers and “bell wire” are necessary components of a wired doorbell installation.  A doorbell transformer coverts the high voltage electricity in your home to a lower voltage for your doorbell product.


A doorbell transformer is used to connect your wired doorbell to your home’s power supply and transform it into a voltage your wired doorbell can use. The doorbell button and wired doorbell are both connected to the doorbell transformer with “bell wire.”

From the doorbell transformer, your doorbell button is connected using approved bell wired.  Your wired doorbell also connects to your transformer using bell wire as well.
