Rule 51.6-A

51.6-A.    Marking Of Poles

(1)    Wood or metal poles which support conductors of more than 750 volts shall have high voltage signs in letters not less than 3 inches in height. The top of such signs shall be neither less than 30 inches nor more than 40 inches below the lowest conductor of each circuit of more than 750 volts. Such signs shall be of weather and corrosion-resisting material, solid or with letters cut out therefrom and clearly legible.

(2)    Optional marking methods:

a)    Similarly located bands of bright yellow color not less than 1 foot in width may be used;

b)    In lieu of marking the pole, crossarms where present may be marked per Rule 52.4.

Rule 51.6-A

51.6-A.    High Voltage Marking Of Poles

(1)    Wood or metal poles which support line conductors of more than 750 volts shall have high voltage signs.  This marking shall consist of a single sign showing the words “HIGH VOLTAGE” or a 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 neither less than 30 inches located between the level of the lowest line conductor of each circuit to nor no more than 40 inches below that the lowest conductor level (See Fig. 51-1). of each circuit of more than 750 volts. Such signs shall be of weather and corrosion-resisting material, solid or with letters cut out therefrom and clearly legible.

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.

(2)    Optional marking methods:

a)    Similarly located bands of bright yellow color not less than 1 foot 12 inches in width; or may be used;

b)    In lieu of marking the pole, crossarms where present may be marked per Rule 52.4.  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 have high voltage signs.  This marking shall consist of a single sign showing the words “HIGH VOLTAGE” or a 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 Fig. 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:

a)    Similarly located bands of bright yellow color not less than 12 inches in width; or

b)    Crossarms where present may be marked.  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.
