wire size chart nec The 310 16 table is basically an ampacity chart it tells us what is the ampacity of copper and aluminum wires The full name for this table is Table 310 16 Ampacities of Insulated Conductors with Not More Than Three Current Carrying Conductors in

This table tells you what gauge wire AWG or kcmil you need to use for services and feeders ranging from 100 amps to 400 amps current It gives us the AWG or kcmil number for copper and aluminum wires same as copper clad aluminum wires We will look at the complete table further on 310 12 A Services part Conductor Ampacity Based on the 2017 National Electrical Code Single Phase Dwelling Services and Feeders NEC 210 19 Conductors Minimum Ampacity and Size Correction and Adjustment Factors See NEC Tables 310 15 B 2 a

The new version of the National Electrical Code NEC 2020 includes Article 311 regarding Medium Voltage Conductors and Cable This Article was added to improve overall usability of the NEC in the previous versions the ampacity tables for medium voltage cables were in Article 310 while the installation requirements were in Article 328 Conductor Sizing and the National Electrical Code The National Electrical Code requirements for conductor sizing and overcurrent protection have always been confusing and complex Factors that must be consider include Continuous loads Terminal temperature ratings Conductor insulation Conductor ampacity Special application

For motors marked with design letters B C or D conductors having an insulation rating of 75 C 167 F or higher shall be permitted to be used provided the ampacity of such conductors does not exceed the 75 C 167 F ampacity NEC 2014 Article 110 14 Table 5 Continued Type Size AWG or kcmil Approximate Diameter Approximate Area mm in mm2 in 2 THHN THWN THWN 2 14 2 819 0 111 6 258 0 0097 12 3 302 0 130 8 581 0 0133
