UL 2237 OUTLINE
UL Outline of Investigation for Multi-Point Interconnection Power Cable Assemblies For Industrial Machinery
|Publication Date:||29 January 2018|
This outline of investigation covers multi-point interconnection power cable assemblies. They may consist of power cable assemblies, male and female power cable fittings, panel-mounted power cable/conductor fittings and feeder-tap power cable fittings 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 1000 V.
These interconnection power cable assemblies may be used in an industrial environment to distribute the power to branch circuits, including motor branch circuits, of industrial machinery.
Devices covered under this outline of investigation are only intended for indoor use, unless otherwise identified.
The power cable assemblies covered under this outline of investigation are rated 1000 V or less, and are intended to be used on 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 600 V. Each power cable assemblies and fittings are 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.
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 structure. The power cable assemblies and mating fittings may be connected to the fixed wiring of the building structure; using a feeder tap fitting or male/female cable fitting.
Power cable assemblies and fittings covered under this outline of investigation 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 188.8.131.52, of the National Fire Protection Association Electrical Standard for Industrial Machinery, NFPA 79.
This outline of investigation does not cover male-to-male cable assemblies or multi-outlet fittings.
These devices are intended for use only with the manufacturer's same line of products covered under this outline of investigation.
These devices are not intended for disconnect use only not for current interrupting. Devices may be investigated for disconnecting means, if so requested and comply with the overload, temperature, resistance to arcing and dielectric voltage withstand testing as described in Table 19.1.
