1.1 These requirements cover modular multi-pole connectors for use with specific identified cable types and when assembled create a modular cable system that consists of electrical cables, field installed or factory assembled modular multi-pole connectors and other associated system devices. Modular cable system connectors and other system devices are only intended for use with mating connectors and system devices of the same manufacturer as specified in the installation instructions.

1.2 These modular cable systems are intended for installation within commercial and industrial locations such as material handling distribution systems and wind turbine towers where the conditions of maintenance and supervision ensure that only qualified persons service the installation.

1.3 These modular cabling systems are only intended for use in accessible locations (as applied to wiring methods) and areas not subject to mechanical damage, in dry locations unless identified for damp, wet or outdoor locations, other than hazardous (classified) locations in accordance with the National Electrical Code, NFPA 70^a

^a NFPA 70, National Electrical Code and NEC are registered trademarks of the National Fire Protection Association, Quincy, MA.

1.4 The modular cable system assemblies and fittings for industrial control, signal and power distribution are intended to be connected as permanently installed branch circuits operating at frequencies between 50 – 60Hz, DC (Direct Current) circuits and at operating potentials of Class 1, Class 2, Class 3 and higher power levels not exceeding 1000 volts between conductors.

1.5 The modular cable system fittings and connectors are only to be assembled or molded on the following cable types: TC (Tray Cable), TC-ER, AC and MC cable in accessible locations as specified in the National Electrical Code, NFPA 70^a.

1.6 This outline does not cover male-to-male connector assemblies.

1.7 This outline does not directly apply to the following but may be used in conjunction with the other applicable standards as indicated below:

1. a) Devices produced integrally with flexible cord or cables that are covered by the Standard for Cord Sets and Power-Supply Cords, UL 817;

2. b) Devices intended for connection to the branch circuit, such as attachment plugs, cord connectors, receptacles, inlets, and outlets, that are covered by the Standard for Attachment Plugs and Receptacles, UL 498;

3. c) Devices solely intended for direct connection to the branch circuit in accordance with the National Electrical Code, NFPA 70, and that are provided with contacts of the pin and sleeve type, covered by the Standard for Plugs, Receptacles, and Cable Connectors, of the Pin and Sleeve Type, UL 1682;

4. d) Devices intended to interconnect industrial machinery and to be installed in accordance with the Electrical Standard for Industrial Machinery, NFPA 79 that are covered by the Outline of Investigation for Multi-point Interconnection Power Cable Assemblies For Industrial Machinery, UL 2237, and

5. e) Devices intended for use in an industrial environment to distribute control signals to remote proximity switches or other control circuit devices are to be installed in accordance with Article 725 of the National Electrical Code, NFPA 70, and are covered by the Standard for Cable Assemblies and Fittings for Industrial Control and Signal Distribution, UL 2238.
