310.104 (A) What is the minimum conductor size for coper at 5001 volts? 6 AWG. 310.106 (A) For doors on cabinets, there shall be an airspace of how much between any live metal part? 1/2 in. 312.11 (2) Conductors in a non metallic box shall have how much free space within for 4 conductors of 14 AWG? 8 in^3.The answer is 4 AWG, 90°C conductor. A 6 AWG, 90°C conductor has an ampacity of 75 amps per (NEC® Table 310.16); but this ampacity can not be used for a 60°C termination. For this circuit, if a 90°C, 6 AWG conductor is evaluated, the ampacity of this conductor must be according to the 60°C conductor ampacity, which is 55A.Code, Standards, And Practices 1, Based On The 2020 Nec Online Materials: Lesson 6 Understanding Conductor Insulation And Nec Specifications Code, Standards, And Practices 1, Based On The 2020 Nec Online Materials: Lesson 7 Introduction To Wiring Devices ...
