When installing an exterior outlet on my home I need to pass the wire through brick. When installing an additional circuit to my garage, I need to pass wire through block.
What is the preferred way to do this? Can I just drill a hole and feed interior 14 gauge Romex through the hole? Or do I need to use UF, MC, or conduit? In no case will there be any direct sunlight exposure as I plan to mount the exterior box directly to the wall and feed the wire through a hole in the back side of the box.
Also, is there any rule regarding the size of the hole? To my garage for instance, I want to run 3-conductor wire through block, in order to add two 110v 20A circuits (one off the black, one off the red). I plan to split them in a junction box to get one circuit down each side of my garage. Then I plan to use a 20A GFCI outlet as the first outlet on each side, immediately after the split, to get GFCI protection throughout -- since as I understand it, I cannot use GFCI breakers with a shared neutral or ground wire.
Any help is appreciated.
Thanks.
