In regard to the Thread Size Feeder?, located at the NEC Forum Area, I have compiled and attached (4) Panel Schedules for example descriptions.

Basic Descriptions:

a. System = 208Y/120V 3 Phase 4 Wire,
b. Panelboard(s) are 30 Space, 200 Amp, 3 Phase 4 Wire, MLO,
c. Loads are as described in the Thread, and per each Schedule's notes.

Post #1 of 2:
Example #1 (PSCHED 1M): 30 Space Panelboard with L-L VA figured as Amperes x 208 / 2; Neutral Load from L-N Circuitry only.

and,

Example #2 (PSCHED 2M): 30 Space Panelboard with L-L VA figured as Amperes x 120; Neutral Load from L-N Circuitry only.
