Notice
23 - AKD-6, Secondary Disconnects, Bullets
This section deals with installing and wiring the legacy secondary disconnect assemblies.
The Emax 2 Retrofill Breaker has these two options:
· All secondary disconnects installed
· No secondary disconnects installed
In case the application requires installing all 3 secondary disconnect blocks (actually, three
sets of bullets), you would select the first option. As secondary disconnects can be pre-
installed on the breaker, wiring the secondary disconnects can be done.
In case the application does not require any secondary disconnect assemblies, take the
second option. Thus, no further wiring is needed.
If the application requires less than 3 secondary disconnect blocks, the customer can choose
the second option, order secondary disconnect blocks as needed, and then install the
secondaries, completing the wiring for the breaker. These options are discussed in the next
sections.
The secondary disconnect block assemblies (Figure 27) for the AKD6 version of the Emax2
Retrofill Breaker can be purchased and installed. Here are the installation instructions:

WIRING
Before installing the breaker, the secondary
disconnects must be wired to the Emax 2
Retrofill Breaker.
Wires with wire markers are provided on the
Retrofill. Make sure that the switchgear
wiring connection points match up with the
original wiring of the cubicle. This ensures
that all wiring connections are properly made.
Wrong connections will cause the breaker to
malfunction.
