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.

Yes, S33930 may be installed in an HCWMU I-Line panelboard.  It requires the same mounting inches as the obsolete SL1200, 15 inches.  It has the same termination provisions, qty (4) #3/0 - 600kcmil.
