I am planning to upgrade from a 100 Amp panel to a 200 Amp panel. In order to do this, I need to run new conduit from the hand hole in my front yard to the side of my house where the current panel is. The electrical company will be pulling the new feed into the conduit but I will be doing the trenching and putting in the conduit. An electrician will replace the panel. The electricians I have discussed with so far all recommend replacing the panel with the new panel in the same location. The new panel would be semi flush which is how the current panel is installed. What I'm struggling with is how the riser from the underground conduit will end up within the wall. The house is built on slab and wondering the best method to get the 90 elbow into the wall. I was told I could use a jack hammer to chisel out a notch in the slab for the PVC conduit riser. But wondering if this is the best way and if it will cause any structural concerns. Or is there some other way to approach this?
