not more than 750 mm (30 in.) from the receptacle it controls, and located in the supply circuit ahead of the receptacle. Circuit breakers or switches located in power outlets complying with this section shall be permitted as the disconnecting means.

(C) Receptacles. All receptacles shall be listed and of the grounding type. Every electrified truck parking space intended to provide an electrical supply for transport refrigerated units shall be equipped with one or both of the following:

(1) A 30-ampere, 480-volt, 3-phase, 3-pole, 4-wire receptacle

(2) A 60-ampere, 208-volt, 3-phase, 3-pole, 4-wire receptacle

FPN: Complete details of the 30-ampere pin and sleeve receptacle configuration for refrigerated containers (transport refrigerated units) can be found in ANSI/UL1686, Standard for Pin and Sleeve Configurations, Figure C2.ll.
For various configurations of 60-ampere pin and sleeve receptacles, see ANSI/UL1686.

626.32 Separable Power Supply Cable Assembly. A separable power supply cable assembly, consisting of a cord with an attachment plug and cord connector, shall be one of the types and ratings specified in 626.32(A), (B), and (C). Cords with adapters and pigtail ends, extension cords, and similar items shall not be used.

(A) Rating(s). The power supply cable assembly shall be listed and be rated in accordance with (1) or (2).

(1) 30 ampere, 480-volt, 3-phase

(2) 60 ampere, 208-volt, 3-phase

(B) Cord Assemblies. The cord shall be a listed type with four conductors, for 3-phase connection, one of which shall be identified in accordance with 400.23 for use as the equipment grounding conductor. Extra-hard usage cables rated not less than 90°C (194°F), 600 volts, listed for both wet locations and sunlight resistance, and having an outer jacket rated to be resistant to temperature extremes, oil, gasoline, ozone, abrasion, acids, and chemicals, shall be permitted where flexibility is necessary between the electrified truck parking space supply equipment and the inlet(s) on the TRU.

(C) Attachment Plug(s) and Cord Connector(s). Where a flexible cord is provided with an attachment plug and cord connector, they shall comply with 250.138(A). The attachment plug(s) and cord connector(s) shall be listed,

by itself or as part of the power-supply cable assembly, for the purpose and shall be molded to or installed on the flexible cord so that it is secured tightly to the cord at the point where the cord enters the attachment plug or cord connector. If a right-angle cap is used, the configuration shall be oriented so that the grounding member is farthest from the cord. An attachment plug and cord connector for the connection of a truck or trailer shall be rated in accordance with (1) or (2) as follows:

(1) 30-ampere, 480-volt, 3-phase, 3-pole, 4-wire and in- tended for use with a 30-ampere 480-volt, 3-phase,

3-pole, 4-wire receptacles and inlets, respectively, or

(2) 60-ampere, 208-volt, 3-phase, 3-pole, 4-wire and in- tended for use with a 60-ampere, 208-volt, 3-phase,

3-pole, 4-wire receptacles and inlets, respectively.
