Good maintenance practices call for periodiic
inspection of all electrical apparatus. Terminal lugs
and bus connections should be periodically checked
for lightness of the connections to avoid excessive
heating and premature failure. The Moulded Case
Switches employed in the equipment have self
wiping contacts built in to the design of the switch.
Periodical operation of switches under load
conditions will remove any high resistance film that
might deelop on power contact surfaces.
