Thanks Greg. As far as getting into the wall, the issue is that I'm going to have to cut the hole in the top plate to feed the subpanel. This is a service change is an existing small church. I'm going to have to run 2" conduit from the outside service location, in the attic, and over and down an existing wall. Going to be hot:( and I understand from previous construction, that I'll be having to go through (2) top plates to get down into the wall:( Going to be an exciting job. Suppose to do it Thursday. Suppose to have a high of 86 degrees here. I better get me some wet cloths etc... to cool me down in the attic:(
