Grounded Doorbell Transformer??

Posted by ardmi (My Page) on

How can I tell if my door bell transformer is grounded with it mounted to a box?

I have an old one without a ground wire and new one with a ground wire. I have conduit and outlets are grounded thru that.

The new transformer has a plastic screw locknut that goes thru the knockout. If I didnt have the ground wire hooked up, would I still be grounded thru the box?

Did I get the wrong type of transformer for a metal box?

The secondary side of the doorbell transformer is not typically grounded. If your transformer has a ground wire, it grounds the metal frame and you should hook it up.
