What is the difference between headroom and dedicated electrical space? (110.26(A) and 110.26(F)(1)(a))

Headroom is actually addressed in 110.26(E).

The dedicated space required by 110.26(F)(1)(a) provides space for future expansion of the electrical system by restricting foreign systems from being installed in the dedicated space.
Headroom is so you don't bump your head while working on the electrical equipment.

This is what I tell the mechanical engineers who want to know where they can run pipes and ducts.
(1) The space directly above the panel (i.e., the 22 inch by 6 inch footprint) is mine. If they need to run anything directly over a panel, it must be 6 feet above the top of the panel, and there must be a drip shield. That's the "dedicated space."
(2) As I stand in front of the panel, anywhere within the "working space," the space over my head must be kept clear, from the floor to 6.5 feet above the floor. That's the "headroom."
