1 Scope

1.1 This standard covers multi-point interconnection power cable assemblies. They may consist of power cable assemblies, male or female power cable fittings, panel-mounted power cable/conductor fittings and feeder-tap power cable fittings, referred to as the device in this standard, used with industrial machinery in accordance with the National Fire Protection Association Electrical Standard for Industrial Machinery, NFPA 79 that have system voltages up to and including 1,000 V.

1.2 These interconnection power cable assemblies may be used in an industrial environment to distribute the power to feeder and branch circuits, including motor branch circuits, of industrial machinery.

1.3 Devices covered under this standard are only intended for indoor use, unless otherwise identified.

1.4 Devices covered under this standard are rated 1,000 V or less. Each device is rated in volts and amperes. The electrical ratings are marked, on each device or on a flag label affixed to each individual power cable assembly.

1.5 The cable assembly fittings and panel-mount fittings are intended to be installed in accordance with the manufacturer’s installation instructions. The cable assembly fittings are intended to be assembled or molded on flexible cord. The power cable assemblies and mating fittings are not intended to be used as a substitute for the fixed wiring of the building or structure. The power cable assemblies and mating fittings may be connected to the fixed wiring of the building or structure; using a feeder tap fitting or male/female cable fitting.

1.6 Power cable assemblies and fittings covered under this standard are not intended to make or interrupt current under load conditions. These power cable assemblies and fittings have been investigated to their marked short-circuit current rating. Power cable assemblies and fittings may specify a maximum ampere rating, type of overcurrent protective device, or both. Unless otherwise marked, the power cable assemblies and fittings are intended to be supplied from an overcurrent protective device of the maximum ampere rating permitted by the Relationship Between Conductor Size and Maximum Rating or Setting of Short-Circuit Protective Device for Power Circuits Table, Table 7.2.10.4, of the National Fire Protection Association Electrical Standard for Industrial Machinery, NFPA 79.

1.7 This standard does not cover male-to-male cable assemblies or multi-outlet fittings.

1.8 These devices are intended for use only with the manufacturer’s same line of products covered under this standard.

1.9 These devices are not intended for disconnecting means under load conditions and are marked as described in 3.

Exception: Devices may be investigated for use as a disconnecting means under load conditions, if so requested and the device complies with the overload, temperature, resistance to arcing and dielectric voltage withstand testing as described in .
