I have a post Katrina modular home on a slab. It's over built and has solid foam insulation between the walls. I think they must of run the wire to the panel before putting the foam to it. My problem is: Whats the best method of getting a 10-3 UF through the foam to the panel. The panel is 14 inches wide (between studs) and all the romex and main power is coming into the top. There are spare knockouts on top but the holes coming in are full of wire. Has any body had this problem before? Help...suggestions.
