At the incoming side, this panel will have two incomers usually HRC Fuses and one common switch. Through the AMF Relay, the panel works automatically.
Inside the panel there will be one relay for both under & over Voltages. If the incoming supply is under voltage or over, then entire system would trip. Hooter is used in the switchgears for indication of EB supply when DG Supply is in working condition.[/vc_column_text][/vc_column][/vc_row]
