Today's video is a complete lesson on sizing electrical cables according to the NBR-5410 tables! So if you still have questions about this subject, stay tuned because I'm going to show you important details! The first thing you'll think about is, what is the minimum cable to connect an outlet? This answer will be in table 47 of NBR-5410: The table says the following: Lighting circuits - minimum cable of 1.5mm² Power circuits (sockets) - minimum cable of 2.5mm² This table is just a basis so that no one ends up putting too thin a cable for circuits with a current higher than the cable supports. It already determines that for lighting, less than 1.5mm² is not allowed, and for sockets (power circuits) less than 2.5mm² is also not allowed! To start sizing correctly in this case, we must worry about FIVE POINTS! 1 - What is the current of the oven circuit? 2 - How will the cables be installed? 3 - Number of cables per circuit 4 - What type of insulation will the cable have? 5 - How many cables will pass through the same conduit? As a good electrical professional, you don't want to swim, swim and die on the beach, right? There's no point in worrying about all these criteria of the standard and when it comes time to buy the cable, choose a poor quality brand. I've already made several videos here on the channel showing the pirated and unwired cables on the market and I also presented the risks they pose. This class is offered by NAMBEI Fios e Cabos, a partner here at Engehall. We used NAMBEI FLEX 4MM² 750V cables as a reference for the sizing done in this video. I would also like to invite you to visit the NAMBEI website and download the cable sizing tables that I am making available below in the description of this video!
