I-Line selection point
The I-Line jaw and support arrangement must match the panelboard bus. Unit-mount or ordinary bolt-on H-frame variants are different assemblies and should not be substituted by frame size alone.
Installation verification
Confirm the panel label, exact HGA suffix, voltage, fault-current study, load terminals, accessories, and conductor torque. Distribution equipment work should be carried out by qualified electrical professionals following Schneider procedures.
