Electrical – XPS Foam and Plywood behind main electrical panel

electricalinsulation

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?

Most people install their electrical panel in an unfinished part of their basement and don't worry about insulating it.

However, if you are sure the panel will not have to be moved then you can mount it however you like and not have to worry about moving it later.

I would install an oversized piece of foam and plywood to allow for additions later. If you have the room that is.

Good luck!
