Can a Rockwell Centerline 2100 MCC have 15" and 20" deep sections in the same line up?

This article answers the question on whether or not a Rockwell Centerline 2100 MCC can have 15" and 20" deep sections in the same line up.

Typically, once a section is required by design to switch to a 20" deep section, the other associated sections will be changed to 20" deep sections to keep a straight line up.
