Original Version
Rule 51.6-A
51.6-A. High Voltage Marking Poles
which support line conductors of more than 750 volts shall be marked with high
voltage signs. This marking shall consist of a single sign showing the words
“HIGH VOLTAGE”, or pair of signs showing the words “HIGH” and “VOLTAGE”, not
more than six (6) inches in height with letters not less than 3
inches in height. A pair of signs may be stacked to a height of no more than
12 inches. Such signs shall be of weather and corrosion–resisting material,
solid or with letters cut out therefrom and clearly legible.
The
top of such sign(s) shall be located between the level of the lowest line
conductor, energized in excess of 750 volts, on
the pole to no more than 40 inches below that conductor level (see Figure 51-1).
Poles
that support risers of more than 750 volts, which are not supporting line
conductors of more than 750 volts, shall be marked with a high voltage sign(s).
The top of such sign(s) shall be located between the level of the lowest
exposed energized portion of the riser to no more than 40” below that portion
of the riser.
Optional marking methods:
(1)
A
similarly located bands of bright yellow color not less than 12 inches
in width installed no more than 40 inches below the lowest line conductor,
energized in excess of 750 volts;
or
(2) When high voltage supply equipment is installed on a pole, a sign may be installed so that it approximately encircles the pole, and the top of the sign shall be located no more than six (6) inches below the equipment and above all communication line conductors and supply line conductors energized at 0-750 volts.
EXCEPTION: 0-750 volt supply conductors installed on a combination arm where the side of the arm supporting the circuit in excess of 750 volts is marked in accordance with optional marking method 3 below.
or
(3) Crossarms where present may be marked in lieu of marking the pole. Such signs shall be placed on the face and back of each crossarm supporting line conductors (see Rule 20.8-C), except that high voltage signs are not required on the inside faces of double arms.
Combination arms shall be marked with high voltage signs only on portions supporting line conductors of more than 750 volts.
Crossarms that support risers of more than 750 volts which are located on poles that do not support line conductors of more than 750 volts shall be marked with high voltage signs on the face and back of each crossarm.
