This electrical SLD (Single Line Diagram) depicts a comprehensive Main LT cum AMF (Automatic Mains Failure) Panel configuration for power distribution systems. The drawing shows a 750 KVA/415V DG set integration with electrical and mechanical interlock between the power sources. The panel features a 2000A TP+N aluminum bus bar system as the main distribution backbone. The drawing includes multiple feeders with detailed specifications: F-01 (750A FP MCCB), F-02 (800A FP MCCB), F-03 (1250A FP ACB), F-04 (1200A TP ACB), F-05 (250A FP MCCB), and F-06 (1250A FP ACB). Each feeder is designated for specific purposes including Fire Pump Panel (75 kW), Utility Panel (300.15 kW), Main Panel (525 kW), APFC Panel (300 KVAR), and two spare feeders. Cable specifications indicate 3.5C 185 sq.mm LT XLPE AL/AR cables for power distribution. The AMF controller provides automatic changeover functionality during mains failure, with the entire system featuring power metering, protective devices, and control circuitry. The interlock system prevents simultaneous connection of both power sources – a critical safety feature for DG set applications.
