Rule 20.8

20.8    Conductor means a wire, or combination of wires not insulated from one another, suitable for carrying electric current.

A.    Lateral Conductor means a conductor extending in a general horizontal direction and usually at an angle of approximately 90 degrees to the direction of the line conductors.

B.    Line Conductor means an overhead conductor which extends from the last point of support on one overhead line structure to the first point of support on another overhead line structure.

C.    Open Wire Conductors mean communication conductors separately supported.

D.    Unprotected Conductors means supply conductors, including but not limited to lead wires, not covered by a “suitable protective covering” (see Rule 22.2), grounded metal conduit, grounded metal sheath or shield, or impregnated fiber and not enclosed in a grounded metal pole.  The provisions for the use of these various types of coverings are specified in certain of these rules.

E.    Vertical Conductor means a conductor extending in a general vertical direction between conductor levels on an overhead line structure.

F.    Insulated Conductors, suitable, means supply conductors which are surrounded by an insulating material, the dielectric strength of which is sufficient to withstand the maximum difference of potential at normal operating voltages of the circuit without breakdown or puncture.  A weather-resistant covering of a supply conductor does not meet the requirements of this rule as to a suitable insulation.

G.    Terminal Fittings are the terminal equipment used in terminating the conductors of runs and risers and include cable potheads and conduit entrance fittings.
