7.4.3.2 A three-conductor flexible cord with ground shall be provided with conductor identification to identify grounded and grounding conductors. A jacketed cord such as a SJT type shall have the grounding conductor within the jacket colored green or green with a yellow stripe and the grounded conductor shall be colored white or gray.
7.4.3.3 A component with no accessible dead-metal parts is not required to be provided with a supply cord of the grounding type, when identified for use in an end-product with no dead metal needing to be grounded or only for use in an end-product such as portable luminaires where under certain uses grounding is not required.
7.4.3.4 When a two-conductor flexible cord is provided for connection to the source of supply and polarity is required, the conductors shall be connected to a polarized parallel-blade attachment plug with the identified grounded conductor (neutral) connected to the wider blade. A parallel cord such as Type SPT-2 shall have a stripe, ridge, or groove on the exterior of the cord surface of the grounded (neutral) conductor for identification.
7.4.3.5 A power supply cord shall be minimum 18 AWG (0.82 mm2).
7.4.3.6 The power supply cord provided on a unit designated for dry location only shall be Type SP-2, Type SPE-2, Type SPT-2, or heavier. The power supply cord on a product intended for use in wet locations shall be additionally rated for outdoor use by a surface marking “W” or “Water Resistant.”
7.4.3.7 A power supply cord shall be minimum 1.5 m (5 ft) in length. The length shall be measured from the point where the cord emerges from the unit, after any strain-relief means provided, to the point where the cord enters an attachment plug.
7.4.3.8 Where a knot in a flexible power supply cord serves as strain relief, the surface upon which the knot contacts or bears shall not have burrs, fins, sharp edges, and projections that could damage the insulation on a cord.
7.4.3.9 A power supply cord shall be provided with a bushing at the point where the cord passes through an opening in a metal enclosure or through a non-rounded opening of a polymeric enclosure. The bushing shall be secured in place and have a smooth, rounded surface against which the cord bears. The bushing shall be nonmetallic if the cord is Type SVT or lighter.
7.4.3.10 The attachment plug of a cord-connected unit shall be configured for a 15- or 20-A branch circuit receptacle and shall comply with either the requirements in the Standard for Attachment Plugs and Receptacles, UL 498, or the Standard for Cord Sets and Power-Supply Cords, UL 817, or both.
7.4.4 Leads, terminals, and connectors for other than branch circuit connections
7.4.4.1 General
7.4.4.1.1 Input and output leads, terminals and connectors shall be rated for the voltage, current and temperature involved.
7.4.4.2 Leads
7.4.4.2.1 Input and output leads shall comply with the requirements for internal wiring of 7.3 and be of sufficient length to allow for the intended connection.
7.4.4.3 Output connectors
7.4.4.3.1 A unit with multiple Class 2 or LVLE supply or load connections where interconnection could cumulatively exceed Class 2 or LVLE limits shall be provided with polarized connectors that inhibit such interconnection.
