scope:

This standard applies to the materials, constructions, and testing of assemblies or single conductors intended for field lashing, of extruded dielectric insulated electric current carrying phase conductors and bare or covered neutral electrical conductors used as weather resistant wires and cables suspended from supporting structures for the overhead distribution of electrical energy.

This standard is intended to apply to the following multiplexed wire and cable constructions:

Neutral Supported Service Drop Cables, and

Neutral Supported Secondary Distribution Cables.

The use of these service drop and secondary distribution cables is limited to circuits not exceeding 600 volts phase to phase, or 480 volts phase-to-ground, and to a normal service conductor temperature rating of 75 °C or 90 °C.
