The notes to Table 130.4(E)(a) of NFPA 70E-2027 state that all dimensions run from the exposed energized part to the person, that a single-phase system above the voltage the note gives selects its range from the maximum phase-to-ground voltage multiplied by the square root of three, that an exposed movable conductor is one whose distance is not under the person's control, such as a pole-supported overhead line, and that the restricted approach boundary assumes an elevation below the limit the note states, with adjustment above it.
