Replace new brushes
Check whether the transmission lines
touches leaves and branches etc. If so,
trim them.
Check from the users whether their own

been in that house. Get them not to use
the appliance that caused this situation.
Replace the RCCB

Log Sheet
The log book should have a separate column for each meter reading of a power house. These meters depend upon
(three / single phase) type and manufacture of equipments. In addition the time, date and signature of the operator
are required.
