N.C. Gen. Stat. § 7A-97
In all trials in the superior courts there shall be allowed two addresses to the jury for the State or plaintiff and two for the defendant, except in capital felonies, when there shall be no limit as to number. The judges of the superior court are authorized to limit the time of argument of counsel to the jury on the trial of actions, civil and criminal as follows: to not less than one hour on each side in misdemeanors and appeals from justices of the peace; to not less than two hours on each side in all other civil actions and in felonies less than capital; in capital felonies, the time of argument of counsel may not be limited otherwise than by consent, except that the court may limit the number of those who may address the jury to three counsel on each side. Where any greater number of addresses or any extension of time are desired, motion shall be made, and it shall be in the discretion of the judge to allow the same or not, as the interests of justice may require. In jury trials the whole case as well of law as of fact may be argued to the jury.
