What does AFCI (Arc-Fault Circuit Interrupter) mean?
The 2014 NEC requires that most inverters be equipped with an AFCI, which enables the inverter to shut down for safety reasons if an arc is detected.
What should designers verify about AFCI requirements before selecting inverter equipment?
Safety and code terms should be read together with the applicable code edition, authority having jurisdiction, equipment listings, and manufacturer instructions. A glossary definition can explain the concept, but it should not be treated as a substitute for project-specific code review.
Practical design considerations
- Confirm the applicable code edition and local authority having jurisdiction before making a compliance statement.
- Match the term to listed equipment and the manufacturer's installation instructions.
- Avoid broad safety claims unless the exact product, configuration, and source are known.
