I need to mount a 110V-24V transformer for the ventilation equipment in my garage. I also have a doorbell transformer on the wall in my garage that I'd like to enclose. The doorbell transformer is mounted on the plate covering a 1-gang metal box in the wall. So, I thought I'd accomplish both of these by removing the doorbell transformer from the existing box, mounting a Wiegmann 8x8x4 box over the 1-gang box, and mounting both transformers in the box. Since I have 110V in the box, this should be easy.
Just wondering if you think this is a good idea, and would meet code. I like to do everything to code, or better.
