4. Excessive heating can reduce spring tension
on the primary connection stabs. Check
stab spring tension regularly, especially
during excessive heat conditions.
5. Excessive heat can cause the wiring and
cable insulation to breakdown. Check
all wires and cables for any evidence of
melting, discoloring, and deterioration.
6. The isolating switch mechanism has a
life expectancy of approximately 10,000
operations. If the application requires
that the mechanism operates more than
twice each day, the mechanism should
be checked at the end of each 1000
operations, otherwise a yearly inspection is
recommended.
7. Periodic dimensional inspections of
the isolating switch mechanism and
mechanical interlocks are strongly
recommended.
8. Check all dimensions when any part
of the isolating switch mechanism and
mechanical interlock is replaced to ensure
that the system is in safe working order.
