Somebody else might have a better definition, but I think for code purposes "switchgear" is just a "switchboard" as defined in article 100. Compare this to the definition of "panelboard" when discussing breaker panels.

"Switchgear" normally sits on a housekeeping pad. I know, so do MCC's. But panelboards normally come in to variations, Residential & light commercial like a QO from Square D, or they are they are regular Panelboards like "I Line" from Square D.

Big difference in the light commercial vs standard is sizing in a wall. Standard Panelboard is 6 inches deep, and 20 inches wide at the minimum, vs Light commercial designed to fit inside a 2" X 4" and is 14.5" widewall.

225Amps, 3 phase is the end of "cheap" panels, they go up significantly after that.
