Webrequired 60. This is where a conductor with a higher temperature rating becomes useful. A 4 AWG THHN conductor has a 90°C ampacity of 95A. Again, looking at the table at the bottom of Table 310.16, a factor of .87 must be used, due to the 45°C ambient. This yields a new ampacity of 82.65, which is adequate for the required 60A ampacity. Webrating and conductor material, determine conductor size with sufficient ampacity to serve the load current, as modified by P7 and P8, if applicable. Proceed to D9. P2: Using Table 310.4, determine applicable temperature rating of insulation based on installation parameters, such as wet, damp, or dry location. Proceed to D3. P3: Determine ampacity ignition act 3
