Knowing how to determine the exact maximum ampacity of an electrical conductor is a crucial requirement to ensuring a safe and adequate installation. The number of conductors in the same raceway that are carrying current can affect conductor ampacity, as can the ambient or surrounding temperature. Watch this video and follow along with the text from the book to hear Mike and his team explain how to evaluate these factors to make the proper choice when sizing electrical conductors… https://www.mi

Now for those of you who may say; Jeff why does the NEC reduce the ampacity based off the amount of conductors?🧐⚡️ In principal, as you add more conductors into a raceway, collectively they will produce more and more heat. As a result, the insulation of these conductors, if operating at their standard ampere ratings with no adjustment could deteriorate (melt). We have to apply this percentage to mitigate the added heat that will accumulate as a result of adding more conductors into a singular r
