Nice Motor Circuitry descriptions post, Tesla!
I have dealt with many complaining Persons, over the Years, when applying Article 430 allowances to Motor Circuits - be it in the Field, or per my Plan Sets.
Most Commonly heard statements:
"You Cannot use #6 THHN CU. with a 90 Amp Breaker"
or
"You Cannot use #4 THHN CU. with a 125 Amp Breaker"
I guess the responses:
"Right; I could have used a 125 Amp Breaker with the #6s"
and/or
"Right; I could have used a 175 Amp Breaker with the #4s"
was more smart-aXX than resourceful!
