3. 4 years

4. 2 years

The correct answer is: 3 years

The National Electrical Code (NEC) is published every three years by the National Fire Protection Association (NFPA). This cycle allows for the incorporation of new advancements in electrical safety, technology, and practices to ensure that the code remains relevant and effective in addressing contemporary issues in the electrical industry. The three-year interval provides a balanced approach, giving stakeholders, including professionals, manufacturers, and regulatory bodies, sufficient time to review changes and updates while still ensuring that the code evolves in a timely manner to reflect current standards and practices. Therefore, the frequency of publication is designed to promote safety and adapt to new technologies and safety concerns that may arise over time.
