Note 1—
For this schedule, a conductor is taken to be insulated if it is insulated in accordance with AS/NZS 5000.1 (Electric cables—Polymeric insulated—For working voltages up to and including 0.6/1 (1.2) kV) or AS/NZS 3560.1 (Electric cables—Cross-linked polyethylene insulated—Aerial bundled—For working voltages up to and including 0.6/1(1.2)kV). Otherwise, it is taken to be uninsulated.
Note 2—
Either the vertical clearance or the horizontal clearance stated must be maintained. Also, in the zone outside the vertical alignment of the building, road cutting, embankments and similar places, either the horizontal clearance from the vertical alignment or the vertical clearance from the horizontal level on which a person is likely to stand must be maintained.
