Single line diagram for a main low voltage distribution board (QGBT) for a 1st basement installation. its a 380/220V 60Hz system using a 630A Schneider Interpact switch and PM-5200 multimedidor for the main feed. I’ve mapped out the load schedule with all the circuit tags, power specs in kW/kVA, and conductor sizes. Components are mostly Schneider, incl. NG125H breakers, DPS protection, the usual. We’ve got technical notes for NBR 5410 and NR-10 safety standards too. Feeders go out to the pharmacy, kitchen, and admin sub-panels, plus some spares. Connections from busways NE-A and NE-B are clearly marked with all the details. Diagrama unifilar do quadro QGBT 104, incluindo tabela de cargas e especificações técnicas.
