Original General Order 95

Section II

Definitions of Terms as Used in The Rules of This Order

21.7    Lines means those conductors together with their supporting poles or structures and appurtenances which are located outside of buildings.

A.    Conflicting Lines (lines in conflict or conflicts) mean lines so situated with respect to each other ( except at crossings) that the overturning of one line will result in contact of its poles or conductors with the poles or conductors of the second line, assuming no conductors are broken in either line; except that line on opposite sides of a thoroughfare are not considered as conflicting if separated by a distance not less than 60 per cent the height of the higher pole line above the ground line and in no case less than 20 feet ( see App. G, Fig. 1).

B.    Colinear Lines mean:

Conflicting lines so situated that one line is wholly or partly over the other line, often called “overbuild’

Conflicting lines not “overbuilds” but not separated a horizontal distance of less than the required pin spacing of the highest voltage circuit involved

Conflicting lines not “overbuilds” but separated a horizontal distance of less than one foot, regardless of pine spacings.  (See App. G, Figs. 2 and 3.)

Note    For the purpose of measurement, the horizontal distance between the conflicting lines shall be that distance measured horizontally between vertical planes passing through the adjacent extremities of the conflicting lines.

C.    Tower Lines (Class H, L and T) mean supply lines, the supporting structures of which are of steel or other metal and have a maximum outside dimension of more than 4 feet measured either along or across the line in a horizontal plane at the ground level.  Metal supporting structures, “A” frames or “H” structures, having a dimension from outside of one support to outside of another support greater than 4 feet at the ground level will be classified as towers.

Note    Steel or metal structures having maximum outside dimensions of 4 feet or less, measured along and cross the line in a horizontal plane at the ground level, will be classified as poles under supply lines.
