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. Where a flexible cord is provided with an attachment plug and cord connector, they shall comply with 250.138(A). When the interrupting device of the personnel protection system specified in 625.22 is located at the attachment plug, or within the first 300 mm (12 in.) of the power-supply cord, the overall cord length shall be not greater than 4.6 m (15 ft).For stationary equipment in accordance with 625.44(B), the power supply cord shall be not more than 1.8 m (6 ft) long and the equipment shall be installed at a height that prevents the power supply cord from contacting the floor when it is connected to the proper receptacle.For portable equipment in accordance with 625.44(A), the power supply cord shall be not more than 300 mm (12 in.) long.When the interrupting device of the personnel protection system specified in 625.22 is located within the enclosure of the supply equipment or charging system, the power-supply cord shall be not more than the length indicated in (i) or (ii):.Have an overall length as specified in either of the following:.Have an ampacity as specified in Table 400.5(A)(1) or, for 8 AWG and larger, in the 60☌ columns of Table 400.5(A)(2).Hard service cord, junior hard service cord, or portable power cable types shall be listed, as applicable, for exposure to oil and damp and wet locations. Be any of the types specified in 625.17(B)(1) or hard service cord, junior hard service cord, or portable power cable types in accordance with Table 400.4.The cable for cord-connected equipment shall comply with all of the following: The allowable ampacities of conductors used with 15-minute motors shall be the 30-minute ratings increased by 12 percent.ġ For 5 to 8 simultaneously energized power conductors in raceway or cable, the ampacity of each power conductor shall be reduced to a value of 80 percent of that shown in this table.Ģ For 4 to 6 simultaneously energized 125☌ (257☏) ac power conductors in raceway or cable, the ampacity of each power conductor shall be reduced to a value of 80 percent of that shown in this table. Note: Other insulations shown in Table 310.4(A) and approved for the temperature and location shall be permitted to be substituted for those shown in Table 610.14(A). Types FEP, FEPB, PFA, PFAH, SA, TFE, Z, ZWįor ambient temperatures other than 30☌ (86☏), multiply the ampacities shown above by the appropriate factor shown below. Types TA, TBS, SA, SIS, PFA, FEP, FEPB, RHH, THHN, XHHW, Z, ZW Up to Three ac 2 or Four dc 1 Simultaneously Energized Conductors in Raceway or Cable Up to Four Simultaneously Energized Conductors in Raceway or Cable 1 Based on Ambient Temperature of 30☌ (86☏).
