Can a VDF enclosure be considered a motor control center? Each VFD has overcurrent protection,control wiring and the frequency drive. They are approximately. 30" wide, 72" tall and 24" deep.

Art 100
Motor Control Center
An assembly of one or more enclosed sections having a common power bus and principally containing motor control units.

Art 430
Controller
For the purpose of this article, a controller is any switch or device that is normally used to start and stop a motor by making and breaking the motor circuit current.

I believe your VFD would be a controller.

VFDs are not commonly connected to a "common power bus". If not so connected, they can't be a MCC.
