General Provisions
12.1 Construction and Reconstruction of Lines
The requirements apply to all
such lines and extensions of lien constructed hereafter and shall become
applicable also to such lines now existing, or any portion thereof, whenever
they are reconstructed.
The reconstruction of an element
of a line requires that all elements subordinate to the reconstructed element
meet the requirements of these rules.
For the purpose of this order reconstruction will be constructed to mean
that work which is any way changes the identity of pole, tower or structure on
which it is performed excepting:
A. Service Drops
Service
drops may be added to existing plant without necessitating changes in the
circuit or line from which they originate.
B. Conductors
Conductors
or circuits added to crossarms installed prior to March 1, 1929 will not be
required to afford greater ground clearance than the ground clearance provided
by conductors of the same or higher voltage classifications which are already
in place on such arms. All other
clearances with which such added conductors or circuits are concerned shall be
in accord with these rules.
C. Subordinate Element
An
element (such as a crossarm or a conductor) added to a pole, tower or structure
shall meet all requirements of these rules but does not require any change in
like elements already existing except where the added element is related in
buck arm construction to an existing arm in which case all construction on the
related arms shall meet the requirements of these rules. A crossarm, pole, tower or other structure
to which any subordinate element is added shall meet the strength safety factor
requirements specified in Rule 44.2.
D. Replacement of Poles,
Tower or Other Structures
The
replacement of poles, towers or other structures is considered to be
reconstruction and requires adherence to all strength and clearance
requirements of these rules. The
clearances of the spans adjacent to the new support need not be changed but the
new support shall be such that when the adjacent support is replaced the span
between will meet all the provisions of this Order.
