YOUR PROBLEM MAY BE... ___________________________________________ ???? Check out our content ???? ???? https://linktr.ee/Eletricity ___________________________________________ For correct sizing of conductors, it is necessary to take into account at least 5 criteria according to NBR-5410: 1 - Minimum cross-section; 2 - Current carrying capacity; 3 - Voltage drop; 4 - Protection against overloads; 5 - Protection against short circuits; Item 2 (Current carrying capacity) will depend on some factors: 1-Type of conductor (PVC, EPL or XLPE); 2-(Conductor Material (Copper or Aluminum); 2-Installation Method; 3-Correction by Temperature; 4-Correction by Grouping. Guys, here I mentioned some, but if you open the NBR-5410 standard in the conductor sizing section you will notice that there are a series of rules for correctly sizing the conductor. Among all these methods, in this video we decided to test a correction method that we consider extremely important, but that is often neglected by electrical professionals. The correction method by grouping that directly affects the cable's conduction capacity. If we are going to run loaded cables together, we have to pay attention to this correction method, we know that the cables heat up and the heating temperature of one cable directly interferes with another. We have already shown this here on the channel in the rolled extension video. For those who haven't seen it, I'm leaving the link below: Video 1 - https://bit.ly/2rJpjhz Video 2 - https://bit.ly/33Lu5ZY It is not enough to just take a table and look at the cable current according to its cross-section. This is wrong. We need to know the 5 methods presented above to properly size the conductor for a given load and among all these methods, sizing by grouping is extremely important. In the future, we will talk more about the other sizing methods to keep the electrical professional informed about the need for knowledge and application of the standard's requirements when sizing cables. I hope this video has helped to understand in practice a concept so forgotten by some professionals. I hope to see you in the next videos. ???? A hug to all. ????
