This standard covers insulation piercing connectors used for making electrical connections between insulated, insulated-to-bare, and bare-to-bare conductors rated 600 V or less and 90°C (low voltage aerial bundled cables and bare and insulated line wires) on overhead distribution lines for electric utilities. Underground insulation piercing connector systems rated at 600 V are covered by ANSI C119.1. Since cable and insulation types exist in very different types and configurations, insulation piercing connectors can not be designed for the full range of cable and insulation possibilities (cable cross-section and material, insulation material and thickness). The manufacturer is to indicate the cable and insulation types the connector is designed for, and conformity to this standard shall be established by testing with these cable and insulation types. This standard establishes the electrical, mechanical and environmental test requirements for electrical insulation piercing connectors. This standard is not intended to recommend operating conditions or temperatures.
