Greetings,
What is the typical recommended method of transitioning from underground duct bank into existing building with 12" brick wall? I am thinking the duct bank would stub up into exterior junction box with conduits going from this JB, through the wall, into the interior junction box. Both JBs would be wall mounted and at the same elevation relative to the grade.
If anyone can recommend a good literature on this topic that covers industry practices, that would be much appreciated.
Thanks,
EE
