The secondary compartment or instrument
compartment is located in the front of
the equipment above the lower primary
compartment (circuit breaker or auxiliary
device). The compartment is provided
with a hinged door for access to the low
voltage control devices contained both
on the compartment door and inside the
compartment. Typically, control relays,
indicator lights, and control switches are
found on the door, while terminal blocks,
fuse blocks, and control devices are mounted
inside the compartment. To accomplish
interconnect wiring, multiple openings are
provided between the adjacent secondary
compartments and also between the primary
compartments located immediately below or
above the secondary compartment.
A horizontal passageway is provided across
the lower rear wall of the compartment with
approximately 4” diameter openings provided
between all secondary compartments to
carry the control and instrumentation wiring
between the compartments. Additional
openings may also be provided when the
equipment requires more complex wiring.
There are vertical passageways between
the secondary compartments and the lower
primary compartments.
