Cause:
The SL1200 sub-feed lug kit was applied as the main lugs of a main lugs only HCWMU panelboard.  It may be necessary to replace the main lugs of an existing obsolete HCWMU I-Line panelboard, but the older literature makes no mention of the currently available components which may be used, and the older components mentioned are obsolete and no longer available.
