At this residence, Romex (10/2, 12/2 & 14/2) can be found stapled to the floor joists in virtually every direction (parallel, perpendicular, and across at angles). Some of the parallel runs are along the bottom edge, some are along the vertical side of a joist. The floor joists are approximately 9' or so above the floor.
