Adjustment and correction factor example

In this video I will demonstrate how to apply both the adjustment and correction factors to derate a wire based on the ambient temperature and the number of current carrying conductors in a raceway or conduit. Also discussed will be utilizing NEC Table 310.15(B)(16),
NEC Table 310.15(B)(3)(a), and NEC Table 310.15(B)(2)(a)

This is a nice way to learn Ampacity calculations. They should have included a step further, like to calculate wether the 4/0 would still be ok to run inside that conduit, but they didn’t specify what size conduit was used here so it don’t apply. It’ll be cool if I could find more examples like this online to brush up on the steps but it’s hard to find them online!!

Really good! This may be to methodical and slow for those more experienced but for many the repetition will help drive it home. I guess that if USE is not specified then it will be a matter of economics.

This is good except the code states to use the 60 degree column for under 100 amps and the 75 for over 100 amps I might be wrong but please confirm

I heard the same however I still don't know when to apply this

[@timrxn5414]

Does that mean before or after adjustment and correction factor? Good question

[@okusitinotahitua1020]

why you use the ambient correction factor start at 1/0 please , can you clarify it please?

What about temps that are not on the tables?

Thank you for this

Nice video 👍.. could you do one about how size service entrance feeder for house 200 amps

[@ryanmoses9512]

What if the temperature exceeds the chart
