What is a correct statement regarding the wiring of any radon fan or motor for contractors?

The statement that local codes must still be followed, regardless of certification, emphasizes the importance of adhering to established building codes and regulations when working on radon mitigation systems. Even if a contractor holds NRPP certification, it does not supersede or exempt them from complying with local codes that govern electrical installations and building safety. Local codes are designed to ensure safety, quality, and uniformity in construction and installation practices within a specific jurisdiction.

This principle is critical in the context of radon mitigation, as improper wiring can create safety hazards, including fire risks or system failures. Compliance with local codes ensures that the installation is performed to the standards expected in that area, providing both safety for the occupants and reliability of the radon mitigation system. The focus on local codes reinforces the contractor's responsibility to understand and implement the relevant regulations in their work, ensuring compliance contributes to a safely functioning radon system.
