Test Mode Switch
Pressing this button will cause the trip unit to be in a testing
mode. Current shall not be applied to the breaker at this
state. The switch has a red LED that indicates the state of
the switch (LED On when switch is ON).
CAUTION: With the Test Mode enabled, the EntelliGuard trip unit
will not provide correct protection to the system, which may
result in a trip below desired levels. Power should be discon-
nected from the circuit breaker prior to entering Test Mode.
Ensure that the Test Mode LED is OFF when in normal operation.
Failure to follow this procedure can result in improper operation
of the system.
Phase Simulation
This switch is enabled only if the trip unit is in the Test Mode

will display approximately 100A on each current phase. This
can be viewed on the trip unit LCD under METER menu. The
switch has a red LED that indicates the state of the switch
(LED On when Switch is ON).
