Surface mounted panels are ouside the wall... Surface mounted conduit too...
The line dividing here is the receptical... Otherwise it is Premises Wiring...
Premises Wiring (System). That interior and exterior wiring, including power, lighting, control, and signal circuit wiring together with all their associated hardware, fittings, and wiring devices, both permanently and temporarily installed, that extends from the service point or source of power, such as a battery, a solar photovoltaic system, or a generator, transformer, or converter windings, to the outlet(s). Such wiring does not include wiring internal to appliances, luminaires (fixtures), motors, controllers, motor control centers, and similar equipment.
And right up to the device in the drawer mounted box is a Branch Circuit. If there were a receptical at the wall, it would be utilization equipment....
