If the total current carrying conductor count exceeds three, then the ampacity from Table 310.16 must be adjusted in accordance with Table 310.15 (C) (1) based on the total number of current carrying conductors. Next, we must look at the ambient temperature of where the conductor will be installed.Notes to Accompany Table: Note 1: Note 2: • Maximum size of Type UF is 4/0 AWG • Maximum size of Types THWN and THHN is 1000kcmil • Maximum size of Type THHW is 1000 kcmil • Minimum size of Single Conductor Type USE is 12 AWG Copper, 10 AWG Aluminum Note 3: • The allowable values in the Ampacity Table are based onAmpacity Conductor Size Ampacity AWG or kcmil 90 °C 14 35 12 40 10 55 8 80 6 105 4 140 2 190 1 220 1/0 260 2/0 300 3/0 350 4/0 405 262.6 470 313.1 510 373.7 590 444.4 655 535.3 730 646.4 815 777.7 905 929.2 1005 1111.1 1115 NEC Table 310.15(B)(17) (formerly Table 310.17) Allowable Ampacities of Single Insulated Conductors Rated Up to and ...rating associated with the ampacity of a conductor shall be selected and coordinated so as not to exceed the lowest temperature rating of any connected termination, conductor, or device. ...

The ampacity rating of a wire determines the amperage that a wire can safely handle. In order to properly size a wire for your application, the ampacity ratings for a wire must be understood. However, many different external factors such as ambient temperature and conductor insulation play a part in determining the ampacity of a wire.Wire must not be sized merely for the ampacity, because there is less tolerance for voltage drop (except for very short runs). For example, a 1V drop from 12V causes 10 times the power loss of 1V drop from 120V. Use the following chart as your primary tool in solving wire sizing problems. It replaces many pages of older sizing charts.Secondary URD Aluminum, XLPE Insulated, 600 V, Ampacity Data Ampacity Data continued Cable Construction Single, 2PLX, 3PLX and 4PLX Conductor Size AWG/kcmil Ampacity 75 °C (167 °F) 90 °C (194 °F) 12 20 25 10 30 35 840 45 650 55 465 75 375 85 2 90 100 1 100 115 1/0 120 135 2/0 135 150 3/0 155 175 4/0 180 205 250 205 230 300 230 …
