I'm having a home built that is going to have a gas stove. I have been told that the NEC requires that even if a house is being built with a gas stove that a 220 electrical outlet must still be installed and included in the calculations. May later buy an electric stove, right? My builders electrical contractor did not install this or include it in the calculations for the homes service. He says it is not required under the NEC. Can someone clarify who is right here? Any applicable code sections to reference would be appreciated.
