4.By using an adjustable spanner or particular size spanner, tighten the nuts in the busbar connection for main and emergency switch boards.
5.Check the tightness of the wire connections, which is connected to the circuit breakers.
6.Clean the bus bar and switchboard area with the help of vacuum cleaner.
7.If u find any loose connection or spark, black-out the particular and adjacent bus bar before tightening the nut.
