Original Version
Rule 56.6

A. Guys in Proximity to Supply Conductors of Less Than 20,000 Volts (See Rule 21.3-D for definition of proximity and Fig 45 of App. G)

All portions of guys within both a vertical distance of 8 feet from the level of supply conductors of less than 20,000 volts and a radial distance of 6 feet from the surface of wood poles or structures shall not be grounded, through anchors or otherwise. Where necessary to avoid the grounding of such portions, guys shall be sectionalized by means of insulators installed at locations as specified in Rule 56.7.

All portions of arm guys within 6 feet of points of attachment to wood crossarms, or metal crossarms on wood poles, shall not be grounded if the crossarms support supply conductors of less than 20,000 volts. Where necessary to avoid the grounding of such portions, arm guys shall be sectionalized by means of insulators at locations as specified in Rule 56.7.

All overhead guys which are not grounded (by means of ground wires, grounded anchor guys, attachment to grounded metal poles, or otherwise) shall be sectionalized at the locations measured from each attachment to poles or structures, as specified in Rule 56.7-A (6 feet to 9 feet from attachments).

Guys exposed to conductors of 20,000 volts or more (see App. G, Fig. 52) shall not be sectionalized and shall have their lower ends securely grounded (by means of ground wires, anchor guys, or attachments to securely grounded metal poles or structures). Excepted from the above requirements are:

Guys, all or any portions thereof, which are required to be sectionalized in accordance with Rule 56.6-A because of proximity of wood poles and supply conductors of less than 20,000 volts or in accordance with Rule 56.6-B; and

Guys which are sectionalized by wood strain insulators equipped with arcing horns and designed to provide impulse insulation for lighting conditions.

Guys attached to securely grounded metal poles or structures are not required to be sectionalized except as required by Rule 56.6-A because of proximity to supply conductors of less than 20,000 volts supported on wood poles, or by Rule 56.6-B.

Rule 56.6

A. Guys in Proximity to Supply Conductors of Less Than ~~20,000~~ 21,000 Volts (See Rule 21.3-D for definition of proximity and Fig 45 of App. G)

All portions of guys within both a vertical distance of 8 feet from the level of supply conductors of less than ~~20,000~~ 21,000 volts and a radial distance of 6 feet from the surface of wood poles or structures shall not be grounded, through anchors or otherwise. Where necessary to avoid the grounding of such portions, guys shall be sectionalized by means of insulators installed at locations as specified in Rule 56.7.

B. Guys To Arms Supporting Conductors of Less Than ~~20,000~~21,000 Volts

All portions of arm guys within 6 feet of points of attachment to wood crossarms, or metal crossarms on wood poles, shall not be grounded if the crossarms support supply conductors of less than ~~20,000~~21,000 volts. Where necessary to avoid the grounding of such portions, arm guys shall be sectionalized by means of insulators at locations as specified in Rule 56.7.

Guys exposed to conductors of ~~20,000~~21,000 volts or more (see Appendix G, Fig. 52) shall not be sectionalized and shall be securely grounded (by means of ground wires, anchor guys, or attachments to securely grounded metal poles or structures). Excepted from the above requirements are:

Guys, all or any portions thereof, which are required to be sectionalized in accordance with Rule 56.6-A because of proximity of wood poles and supply conductors of less than ~~20,000~~21,000 volts or in accordance with Rule 56.6-B ; and

Guys which are sectionalized by wood strain insulators equipped with arcing horns and designed to provide impulse insulation for lightning conditions.

Guys attached to securely grounded metal poles or structures are not required to be sectionalized except as required by Rule 56.6-A because of proximity to supply conductors of less than ~~20,000~~21,000 volts supported on wood poles, or by Rule 56.6-B.

A. Guys in Proximity to Supply Conductors of Less Than 21,000 Volts (See Rule 21.3-D for definition of proximity and Fig 45 of App. G)

Guys exposed to conductors of 21,000 volts or more (see Appendix G, Fig. 52) shall not be sectionalized and shall be securely grounded (by means of ground wires, anchor guys, or attachments to securely grounded metal poles or structures). Excepted from the above requirements are:

Guys, all or any portions thereof, which are required to be sectionalized in accordance with Rule 56.6-A because of proximity of wood poles and supply conductors of less than 21,000 volts or in accordance with Rule 56.6-B; and

Guys which are sectionalized by wood strain insulators equipped with arcing horns and designed to provide impulse insulation for lightning conditions.

Guys attached to securely grounded metal poles or structures are not required to be sectionalized except as required by Rule 56.6-A because of proximity to supply conductors of less than 21,000 volts supported on wood poles, or by Rule 56.6-B.
