Phase rotation from the utility is meaningless, except for parallel systems. The exact phase identification at the service entrance is unique to each service. Of course once the phase rotation has been established for a service it need to be maintained throughout the facility
Utilities alway identify the C phase as the high phase and the NEC requires the middle conductor (B phase)to be the high leg and colored orange (99NEC 384-3e & f)
