400.5(A) — 2017 (ampacity tables; cites 310.15(B)(2)(a) + 310.15(C))
400.5 Ampacities for Flexible Cords and Flexible Cables. (A) Ampacity Tables. Table 400.5(A)(1) provides the allowable ampacities, and Table 400.5(A) (2) provides the ampacities for flexible cords and flexible cables with not more than three current-carrying conductors. These tables shall be used in conjunction with applicable end-use product standards to ensure selection of the proper size and type. Where cords and cables are used in ambient temperatures other than 30°C (86°F), the temperature correction factors from Table 310.15(B) (2) (a) that correspond to the temperature rating of the cord or cable shall be applied to the ampacity in Table 400.5(A)(1) and Table 400.5(A)(2). Cords and cables rated 105°C shall use correction factors in the 90°C column of Table 310.15(B) (2) (a) for temperature correction. Where the number of current-carrying conductors exceeds three, the allowable ampacity or the ampacity of each conductor shall be reduced from the three-conductor rating as shown in Table 400.5(A) (3). Informational Note: See Informative Annex B, Table B.310.15(B) (2) (11), for adjustment factors for more than three current-carrying conductors in a raceway or cable with load diversity. A neutral conductor that carries only the unbalanced current from other conductors of the same circuit shall not be required to meet the requirements of a current-carrying conductor. In a 3-wire circuit consisting of two phase conductors and the neutral conductor of a 4wire, 3-phase, wye-connected system, a common conductor carries approximately the same current as the line-to-neutral currents of the other conductors and shall be considered to be a current-carrying conductor. On a 4wire, 3-phase, wye circuit where more than 50 percent of the load consists of nonlinear loads, there are harmonic currents present in the neutral conductor and the neutral conductor shall be considered to be a current-carrying conductor. An equipment grounding conductor shall not be considered a current-carrying conductor. Where a single conductor is used for both equipment grounding and to carry unbalanced current from other conductors, as provided for in 250.140 for electric ranges and electric clothes dryers, it shall not be considered as a currentcarrying conductor.2017: on-disk NFPA scan §400.5(A) - quoted verbatim

400.5(A) — 2023 (ampacity tables; cites 310.15(B)(1)(1))

Where cords and cables are used in ambient temperatures other than 30°C (86°F), the temperature correction factors from Table 310.15(B)(1)(1) that correspond to the temperature rating of the cord or cable shall be applied to the ampacity in Table 400.5(A)(1) and Table 400.5(A)(2). Cords and cables rated 105°C shall use correction factors in the 90°C column of Table 310.15(B)(1)(1) for temperature correction. Where the number of current-carrying conductors exceeds three, the ampacity of each conductor shall be reduced from the three-conductor rating as shown in Table 400.5(A)(3). Informational Note: See Informative Annex B, Table B.2 (11), for adjustment factors for more than three current-carrying conductors in a raceway or cable with load diversity. A neutral conductor that carries only the unbalanced current from other conductors of the same circuit shall not be required to meet the requirements of a current-carrying conductor. In a 3-wire circuit consisting of two phase conductors and the neutral conductor of a 4-wire, 3-phase, wye-connected system, a common conductor carries approximately the same current as the line-to-neutral currents of the other conductors and shall be considered to be a current-carrying conductor.

The individual conductors of all cords, except those of heat-resistant cords, shall have a thermoset or thermoplastic insulation, except that the equipment grounding conductor, where used, shall be in accordance with 400.23(B). 'Rubber-filled or varnished cambric tapes shall be permitted as a substitute for the inner braids. *Elevator traveling cables for operating control and signal circuits shall contain nonmetallic fillers as necessary to maintain concentricity. Cables shall have steel supporting members as required for suspension by 620.41. In locations subject to excessive moisture or corrosive vapors or gases, supporting members of other materials shall be permitted. Where steel supporting members are used, they shall run straight through the center of the cable assembly and shall not be cabled with the copper strands of any conductor. In addition to conductors used for control and signaling circuits, Types E, EO, ETP, and ETT elevator cables shall be permitted to incorporate in the construction one or more 20 AWG telephone conductor pairs, one or more coaxial cables, or one or more optical fibers. The 20 AWG conductor pairs shall be permitted to be covered with suitable shielding for telephone, audio, or higher frequency communications circuits; the coaxial cables shall consist of a center conductor, insulation, and a shield for use in video or other radio frequency communications circuits. The optical fiber shall be suitably covered with flame-retardant thermoplastic. The insulation of the conductors shall be rubber or thermoplastic of a thickness not less than specified for the other conductors of the particular type of cable. Metallic shields shall have their own protective covering. Where used, these components shall be permitted to be incorporated in any layer of the cable assembly but shall not run straight through the center. 'Insulations and outer coverings that meet the requirements as flame retardant, limited smoke, and are so listed, shall be permitted to be marked for limited smoke after the Code type designation. “Elevator cables in sizes 20 AWG through 14 AWG are rated 300 volts, and sizes 10 AWG through 2 AWG are rated 600 volts. 12 AWG is rated 300 volts with a 0.76 mm (30 mil) insulation thickness and 600 volts with a 1.14 mm (45 mil) insulation thickness. 5Conductor size for Types EV, EVJ, EVE, EVJE, EVT, and EVJT cables apply to nonpowerlimited circuits only. Conductors of power-limited (data, signal, or communications) circuits may extend beyond the stated AWG size range. Ail conductors shall be insulated for the same cable voltage rating. “Insulation thickness for Types EV, EVJ, EVEJE, EVT, and EVJT cables of nylon construction is indicated in parentheses.

Table 400.51(A)(1) provides the ampacities for single and three-conductor portable power feeder cables rated greater than 2000 volts. Where portable power feeder cables are used in ambient temperatures other than 30°C (86°F), the temperature correction factors from Table 400.51(A)(2) that correspond to the differing ambient temperature shall be applied to the ampacity in Table 400.51(A)(1). Where the cable will not be completely unwound from the cord reel, the ampacity correction factor based on the number of layers remaining wound on a reel shall be applied as shown in Table 400.51(A)(3). ) Under engineering supervision, conductor ampacities shall be permitted to be calculated in accordance with 310.14(B). )2023: on-disk 2023 rows 400.51(A)-(B) - quoted verbatim
