Can you put a receptacle in the floor right in the middle of the doorway, and have it count as serving the three feet of wall space to the left of the door and the two feet of wall space to the right of the door? I think that the ?wall space receptacle? should be required to be within the wall space itself. I recognize that the present NEC word do not contain that requirement.
"I recognize that the present NEC word do not contain that requirement."
I don't agree. . I think the present wording allows a floor box to be counted only if it is within 18" of the wall. . The floor box in the middle of the doorway opening is not in front of a wall.
Are you measuring 18" diagonally to the doorframe ? . We already decided thumbs down to diagonal measurements when the 5 1/2' [210.52(4)] was discussed. . You can only go floor line [210.52(A)(1)] or wall line [210.52(C)(1)]. . Then you establish a right angle plane that runs up the wall to 5 1/2' and across the floor to 18".
