The QO120M100 and QO124M100 load centers use the same QOM100VH main breaker. Why do the two load centers have different wire ranges?

QO Load Center

Clarification of design feature

Although both of these load centers do use the QOM100VH main breaker, the QO124M100 enclosure is longer than the QO120M100 enclosure, providing adequate wire bending space for the maximum #2/0 AWG size wire that the QOM100VH lug allows. The QO120M100 is restricted to accept a maximum #1 AWG wire because of wire bending space restrictions.
