3.2.2 LOAD
The load side contacts of each switching device are
joined with a bus bar assembly to form a common load
terminal location (Figure 3-4).
3.2.3 TRANSFER MECHANISM
The transfer switch uses Cutler-Hammer SPB Type insu-
lated case circuit breakers and insulated case switches
with a stored-energy mechanism. An electrical operator
automatically recharges the mechanism after the switch-
ing device has been closed. An indicator on the switch
shows whether it is in the
the status of the stored-energy mechanism. (Figure 3-2).
