Digitrip Retrofit System for the ITE
LG-3000 (Frameless) Circuit Breaker
For Kits Supplied with a Breaker Mounted
CPT Only.
Step 11: Connecting the HV Wires
Note:
The power convention of the ITE LG-3000
(Frameless) Breaker is normally Top to Bottom,
meaning the Top Breaker Phase Frames are on
the Line Side of the Breaker and the Bottom
Breaker Stabs are on the Load Side.
The HV Wires from the CPT MUST BE
ATTACHED to the Line Side of the Breaker. If it is
determined that the power flow for the Breaker
application is opposite the normal convention, the
HV Wires must be attached to the Bottom Phase
Frames. In this case, the same bolts used to attach
the PT Wires to the Phase 1 and 2 or Phase 2 and
3 Phase Frames can be used to mount the HV
Wires.
Note:
The Line Side HV Wires are longer than
necessary and are cut during the following
steps. Before cutting the wires, be sure that suffi-
cient length is left so that the connections can be
made to the correct Finger Clusters or Phase
Frames.
A. Assure that the HV Fuses are in an accessible
location, then feed the HV Wires throug the
existing hole near the bottom right corner of the
Breaker Back Plate. Using the wire ties
provided, secure the HV Wires to prevent
movement.
B. Route the HV Wires through the grommet in the
Sensor Mounting Bracket, then towards the top
Phase 1 & 2 or Phase 2 & 3 Breaker Stabs.
