On a new house build I have the opportunity to prep for the main electric panel that will feed the house circuits. This is installed in the basement of a climate zone 5 location. I believe the basement will some day be insulated with rigid foam, so I am considering using about 2" of rigid foam glued to the concrete wall with 3/4" Plywood tapconned into the foam and concrete behind the foam. Then, the panel would install onto the plywood.
Is this a good idea? Am I getting too carried away with insulation, or have any of you seen this done?
