I'm installing some lighting on the outside of my garage. It seems pretty straightforward, but I've got a question regarding the electrical boxes...
I'm using "pancake" boxes. I knockout one of the holes in the back of the box. Then I hold it up where I want it mounted and mark the wall. I take it down and drill my hole. Put it back up and screw into place. Pull the wire through.
How do I clamp the wire so it doesn't pull out of the box? I know that there are clips that can be put into place, but the sheathing of the garage wall precludes my using them. I guess I could put the clip in backwards, but they are wider than the pancake box is high.
Do I just leave the wire loose and depend on the "staple" inside the garage to hold the wire?
Just want to be sure that this will meet code here in Calgary. Don't want to fail my inspection.
Thanks!
