CONEXÃO CORRETA de DOIS QUADROS ELÉTRICOS em CASA de 2 ANDARES | 127 V primeiro e segundo

In this video, I explain the correct connection of two electrical panels in a two-story house, using a 127V single-phase system, very common in Brazil, with a TN-C-S grounding scheme. You will learn step by step: ✔ How to interconnect the main panel and the secondary panel ✔ Installation of the main thermomagnetic circuit breaker ✔ Installation of the surge protection device (SPD) ✔ Correct distribution of phase, neutral, and ground ✔ Safe power supply to the second panel ✔ Correct separation between neutral and ground ✔ Use of an independent residual current device (RCD) for each floor I also explain how the PEN conductor should be separated in the TN-C-S system, how the neutral is referenced to ground potential, and why neutral and ground should not be connected after the differential. This example is based on typical 127V residential installations in Brazil. If you are installing a second electrical panel in your home or want to understand the correct way to make this connection, this video will help you. At the end, I've included other related videos on grounding, conductor sizing, and differential protection. ____________________________________ ELECTRICAL TABLETS: PERÚ AND ARGENTINA:    • Montaje y Cableado de Tablero Eléctrico Do...   MEXICO AND EEUU:    • INSTALACION ELECTRICA RESIDENCIAL Centro d...   CHILE:    • Tablero Eléctrico Domiciliario Chile ACTUA...   ECUADOR:    • Tablero de Distribucion Electrico tipo Cen...   THREE-PHASE:    • Como hacer el cableado de un Tablero Trifa...   OTHER VIDEOS:    • Lo que debes SABER antes de realizar el CA...      • Como instalar Flotador de Tanque de Agua |...      • Principio de funcionamiento de un circuito...
