These are 2 different spaces with 2 different intents.

#1: The working space mentioned in 110.26(A) is for personnel safety, giving room to move or be moved out of the way in the event of an accident. This space requirement applies not only to electrical panels but any electrical equipment that requires servicing. For a small electrical panel installation this dimension is 30” wide by 36” deep by 6.5’ high. Examples would be fuse disconnects, motor starters, VFD’s, etc.

#2: The dedicated equipment space mentioned in 110.26(E) is intended to maintain space about the equipment that may need to be used for future expansion of the electrical system.
