Breaker compartment
Closed-door draw-out circuit breaker
compartments are standard construction with all
switchgear equipment. The circuit breaker
compartment doors remain closed and latched
while the breaker is racked out from the
CONNECTED position, through TEST, to
the DISCONNECTED position.
Breaker compartment doors do not have any
ventilation slots, thus protecting operators from
gases which may be vented by the breaker during
circuit interruption. Additionally, the breaker
compartment, Figure 19 and 20, is enclosed by
grounded steel barriers on the top, sides, bottom,
and front. In the back, a flame-retardant, track
resistant, glass-filled polyester base minimizes
the possibility of fault communication between
compartments or to the bus.
