John,

I hope this message goes through. The last time I posted the computer puked and locked up.
As for the 3 season room, II was not really talking about the "conservatory" style of room. They do have heat, and can be used year round. I was talking about the porch that is converted to a "room" by the loses of terms. The "room" might have screen windows, might not, might even have 1 panel storm windows. Maybe some insulation in the wall, maybe not. They are rarely used in the winter., Would they need outlets as per code?
