51.6-A. High Voltage Marking of Poles

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”, in letters not less than 3 inches in height. 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 of each circuit 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) Similarly located bands of bright yellow color not less than 12 inches in width

(2) Crossarms where present may be marked in lieu of marking the pole. When crossarms are marked this marking shall consist of a single sign showing the words “HIGH VOLTAGE”, or pair of signs showing the words “HIGH” and “VOLTAGE”, in letters not less than 3 inches in height. Such signs shall be of weather– and corrosion–resisting material, solid or with letters cut out therefrom and clearly legible. 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.

51.6-A. High Voltage Marking ~~of Poles~~

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 in 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, ~~of each circuit~~ 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;

(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.

(32) Crossarms where present may be marked in lieu of marking the pole. When crossarms are marked this marking shall consist of a single sign showing the words “HIGH VOLTAGE”, or pair of signs showing the words “HIGH” and “VOLTAGE”, in letters not less than 3 inches in height. Such signs shall be of weather– and corrosion–resisting material, solid or with letters cut out therefrom and clearly legible. 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.

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;

(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.
