Secondary Disconnects (Factory-installed/Field
Installable)
Inputs and outputs to the circuit breaker are wired
through secondary disconnects located on either the top
or the side (Envelope 1 only) of the breaker. The plug-style
secondary disconnects engage mating disconnects in the
breaker cubicle when the breaker is in the TEST or
CONNECT position. Up to 78 points are available so that
all breaker accessories can be wired to dedicated
disconnect points. See Table 6.19 for block location and
Table 6.20 for secondary disconnect parts.

Ground Fault
The EntelliGuard TU Trip Unit provides a non-core CT
input for zero sequence or residual summation current.
The expected ratio is 1A = 100%.
Neutral Rogowski CT’s
The Neutral Rogoswki CT’s are used to measure the
Neutral Current and is required when Internal Ground
Fault is selected on the trip unit. There are two types
available:
1. Encased with Terminal Screws: The Rogowski coil
is encased in a plastic mold with two terminal
screws. No additional mounting hardware is
required as the encasing is molded to the
mounting dimensions. Table 6.21
2. Loose Rogowski Coil with separate mounting
hardware: The coil and mounting hardware are
separate. The coil comes with the two wire leads
for connection to a terminal block. Table 6.21a
