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 ½ inches from metal pins and dead-end hardware.
Guys and space bolts shall have a clearance of not less than 1 ½ 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.

Hardware
Through bolts, metal signs, conduits, metal braces, mounting
bolts and hardware for cutouts or other apparatus, metal street light fixtures,

not less than 1 ½ inches from metal pins and dead-end hardware.
Guys and space bolts shall have a clearance of not less than
1 ½ 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 ½ 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 ½ inches to any through
bolt which is metallically interconnected to dead-end hardware.
