I am enrolled in the electrician program at a tech school and was wondering if there is a good definition of what a basement is? I spent at least an hour going through the NEC trying to find it, but I'm stuck. Our teacher said he would give some bonus points to anyone that could find and answer and he didn't care how we got it.
a basement is defined in the building codes (and I assume the NEC is not going to argue with the building codes over this definition since they have not bothered creating a different definition)-
Uniform Bldg. Code - "Basement is any floor level below the first story in a bldg., except that a floor level in a bldg. having only one floor level shall be classified as a basement unless such floor level qualifies as a first story as defined herein." . . .. now is that confusing or what? . . . however it does go on (in definitions of story, first story) to define what constitutes the 1st floor...I'm sure the bldg. codes in your area will define basements/1st story.

In 336-5(a) the NEC defines the first floor. "For the purpose of this article, the first floor of a building shall be that floor that has 50 percent or more of the exterior wall surface area level with or above finished grade." Can we then assume that if the floor in question is below the first floor that it is a basement? Don(resqcapt19)
