Derating of Conductors Explained

In this video we discuss why we need to derate conductors and how we do it. We look at the NEC 2014 and how it is understood.

Art.310.15(B)(3)(a) in the NEC 2014 that will give you the chart to figure out what percentage to use.

I literally played this video, for the past 3 hours studying all day. Using the 2017 edition.Table 310.15(B)(16) yet the top reads 310.60 on pg 70-150. That was messing me up. Now that I tabbed my book that was half the battle. Turn the page and find #of conductors This video is so perfect for load calculations. Cut the search down by a lot. Keep up the good work

Very well explained, derating always was somewhat a mystery for me, and I've only pulled whatever size I was told to pull. Now I have more knowledge to do a quality job in the field. Thank you.
