Original Version
Rule 52.7-D


52.7-D.    Separation from Metal Pins and Dead-end Hardware

 

Through bolts, metal signs, conduits, metal braces, mounting bolts and hardware for cutouts or other apparatus, metal street light fixtures, metal pole top extensions and metal arm extensions supported by or attached to the surface of wood poles and wood crossarms shall have a clearance of not less than 1 inches from metal pins and dead-end hardware.  Guys and space bolts shall have a clearance of not less than 1 inches from metal pins and dead-end hardware unless contact is intended, in which case a positive electrical contact shall be made.  Any guy contacting or connected to a metal pin or part of dead-end hardware shall not be placed in the climbing space.

52.7-D.    Separation from Metal Pins and Dead-end Hardware

 

Through bolts, metal signs, conduits, metal braces, mounting bolts and hardware for cutouts or other apparatus, metal street light fixtures, metal pole top extensions and metal arm extensions supported by or attached to the surface of wood poles and wood crossarms shall have a clearance of not less than 1 inches from metal pins and dead-end hardware.  Guys and space bolts shall have a clearance of not less than 1 inches from metal pins and dead-end hardware unless contact is intended, in which case a positive electrical contact shall be made.  Any guy contacting or connected to a metal pin or part of dead-end hardware shall not be placed in the climbing space. Bolts and hardware of line equipment and bolts and hardware of insulators, all of which are associated with the same circuit and on the same crossarm, may be metallically interconnected provided a positive electric contact is made.

This rule need not be applied to through bolts and dead-end hard- ware of a single circuit of more than 7,500 volts constructed at the top of a pole in any configuration. On a related buckarm portions of through bolts and dead-end hardware in the climbing space which do not conform with the rule must be covered with a suitable non- conducting material having an insulation value equal to the insulation value of the insulators on the associated circuit.

Guys and space bolts shall have a clearance of not less than 1 inches from metal pins and dead-end hardware unless contact is intended, in which case a positive electrical contact shall be made. Any guy contacting or connected to a metal pin or part of dead- end hardware shall not be placed in the climbing space. No part of any guy may be nearer than 1 inches to any through bolt which is metallically interconnected to dead-end hardware.
