DANGER! Hazardous voltage. Can cause death or
serious injury. Turn off and lock out power supply
before installing PB-Series ELCI / RCBO.
SAFETY INSTRUCTIONS
� The ELCI/RCBO will not protect against a line to line
fault hazard.
� Do not ground neutral on the Load Side of the
ELCI/RCBO.
� Test ELCI/RCBO once a month. See test
instructions below.
� Not for use in portable or cord-connected
applications. Use only in permanently installed
enclosures.
� Do not subject to megger, high voltage or hi-pot test.
Remove ground fault circuit breaker before hi-potting
occurs on the circuit or system. (Ref. Sect. 550-12,
NEC).
� Do not reverse Line and Load connections.
� Do not supply power to the Load connections from
another source as damage will occur. Not suitable
as a source selector.
INSTALLATION PROCEDURE:
1. The ELCI/RCBO should be installed by a qualified
electrician.
2. Turn “OFF” and lock out the power to enclosure in
which ELCI/RCBO is to be installed.
3. Turn “OFF” the ELCI/RCBO handle. Feed the load
side (L1) hot and (N) neutral wires through the
opening in the sensing coil. Connect to the
appropriate load side terminals of the circuit breaker.
Connect corresponding line side (source) wires
directly to the Breaker Line Terminals.
4. Connect the white “pigtail” neutral wire of
ELCI/RCBO to the panel Neutral Bar or the load side
Neutral terminal (see Fig. A).
5. Mount ELCI/RCBO to front panel and mount front
panel to enclosure (may be mounted first, depending
on installation).
6. Turn “ON” power and turn “ON” breaker handle.
Test the ELCI/RCBO as per test instructions below.
7. Place Monthly Test Reminder label in a convenient
place near the or on the panel and instruct
equipment users on test procedures and the
importance of performing and recording monthly
tests.
Fig. A.
TEST INSTRUCTIONS:
1. Turn on the power to the panel.
2. Turn “ON” the ELCI/RCBO handle.
3. Depress the “TEST MONTHLY” button. This will
cause the handle to move to the “OFF” position
indicating that the ELCI/RCBO is functioning
properly. If the handle fails to move to the “OFF”
position the unit MUST
be replaced.
4. Restore power by moving the ELCI/RCBO handle to
the “ON” position.
5. This test is to be performed on a monthly basis and
recorded on the “Monthly Test Reminder” label.
WHEN ELCI/RCBO TRIPS:
The PB-Series ELCI/RCBO opens the circuit when there
is an overload or ground fault condition. When tripping
occurs perform the following steps:
1. Some faults are self-clearing. Try resetting the
breaker once.
2. If breaker is installed as a main circuit breaker, turn
off all branch breakers supplied from this breaker
and try resetting. If the breaker does not trip, reset
branch circuit breakers one at a time to locate a
possible fault in branch circuit.
3. If breaker continues to trip, the device is performing
its intended protection function, which means that a
hazardous condition could exist. A qualified
electrician should be called to evaluate the circuit.
