CODE
c
(AKD-6 SWITCHGEAR) (Fig. s)
These breakers employ the same drawout arrangement as
the Code
A
models described
on page 7. Their
drawout
operation
and breaker
insertion/removal
procedures
are
identical,
but they differ
significantly
in other
aspects. As
indicated
in Table 1, the
AKR-(
)C-75
is a
32004 Ac
frame
size compared
to
the 3000A A model. The
AKR-(
)C-100
is
narrower than
AKR-(
)A-100 (25 versus 33 inches). All
C
models employ finger-type primary disconnects instead of
the tubular studs of the A types per fig.
2.
C breakers cannot be employed as replacements
for
A
types due to their width and primary disconnect
configura-
tion.
