N.C. Gen. Stat. § 15A-1340.22

(1) Limits on Consecutive Sentences. - If the court elects to impose consecutive sentences for two or more misdemeanors and the most serious misdemeanor is classified in Class A1, Class 1, or Class 2, the cumulative length of the sentences of imprisonment shall not exceed twice the maximum sentence authorized for the class and prior conviction level of the most serious offense. Consecutive sentences shall not be imposed if all convictions are for Class 3 misdemeanors.

(2) Consolidation of Sentences. - If an offender is convicted of more than one offense at the same session of court, the court may consolidate the offenses for judgment and impose a single judgment for the consolidated offenses. Any sentence imposed shall be consistent with the appropriate prior conviction level of the most serious offense.
