The correct choice highlights that NCMC 514.2 specifically addresses the prohibitions related to energy recovery ventilation systems in North Carolina. This section of the North Carolina Mechanical Code outlines the conditions under which these systems may not be used or equipped.

Understanding the provisions of NCMC 514.2 is crucial for ensuring proper compliance with state regulations, particularly when it comes to the design and implementation of ventilation systems. By adhering to these guidelines, mechanical engineers and contractors can avoid legal issues and ensure that the systems they install operate efficiently and safely.
