I have a question that relates to a doorbell install that you folks have
been helping me with, along with another transformer install that I have
to do for a AC system. The transformer that had been spec'd out a couple
of years ago for the AC system called for a JBOX with a extension to
give it depth and the transformer would mount directly inside of the box
with the low voltage terminals sticking out, visible and easy to work
on. I want to find the same setup for my doorbell install as the device
will be in a home run closet that is drywalled! It is impractical to rip
open the wall to install on the side of a JBOX. It is easier to just cut
in a retro box that I can dedicate to the transformer and then pull
Romex or THNN from a nearby outlet. What type of transformer fits inside
of a JBOX and what size jbox do I get. I know that I have seen
applications in the past, where the transformer is sticking right out of
the box. Can someone help me with this. I am confused. If I was given
bad info re the AC transformer that it will be a pain to rip out that
box and reposition.
