Why are you choosing #4 wire =95 amps? Question states load for 59 amps? In the 90 degree column, i would choose 75 amps, #6 wire ?

Hi electrical code coach, Thanks for all of your videos. I have a question regarding this video, the question ends at (6:30min), i would like to know, why you choose 130 amp if we have THHN wire in both sections (75 C and 90 C). You always ask for look at 90 C columns. Thanks!!

Excellent question! In that specific question no adjustments/corrections are needed because they are not required because the length of the nipple. Since they are not required you do not use the 90° C column because you are making no adjustments/corrections so you will head straight to the 75°C column Thanks For the Question!!

So on the slide where we are selecting allowable ampacity for a #1 thhn copper conductor , and we’re not using correction factors because the nipple is 24” or less question .. You were saying we could go straight to the 75 degree column and select our wire .. Question is ... there is no thhn in the 75 degree column. Your saying the answer is 130 amps .. Question is .. because there is no thhn in that column... Does that mean we have to go back to the 90 degree column to make our selection ? Leaving the correct answer at 145 ?

Great question! If I'm looking at the same question that you are in the video! The terminals are 75 degrees C so regardless if the wire is listed in that column, unless there is another code for venting it. You will select from the terminal rating column. Have a great day brother!
