Did you know that, in some cases, the aluminum cable delivered by the utility company may be smaller than the copper cable you need to use in your indoor electrical installation? In this video, I will explain why this happens and what factors influence the choice of cable gauge, such as the type of insulation (EPR, PVC), the installation method (aerial or built-in) and the NBR5410 standards, which require the use of copper in residential installations. I will show you how a 16mm aluminum cable may require a 25mm copper cable to support the appropriate current and ensure safety. Don't miss this essential explanation for anyone who wants to understand more about electrical installations and the conduction capacity of cables!
