A NBR 5410 é bem clara em relação ao dimensionamento de cabo e disjuntor para circuito aonde nessa regra do item 5.3.4 ela deixa bem claro de 15 se a corrente do projeto ela é menor ou igual a corrente do disjuntor que por sua vez é menor ou igual a a capacidade de suportar corrente do cabo já com todas as condições e variáveis previstas e calculadas fica fácil de dimensionar o cabo e o disjuntor para o circuito sem a necessidade de utilizar uma sobra ou deixar uma margem de segurança para isso!

🚁 Quando um helicóptero leva peças metálicas, ele vira um gerador voador: o atrito com o ar gera eletricidade estática! Antes de encaixar qualquer peça, o trabalhador precisa descarregar essa carga pra não levar um choque perigoso. Montar torres no ar exige sincronia total!
