Do your PV designs comply with new NEC 2014 regulations?

摘要

The 2014 National Electrical Code (NEC) for Solar Installations was recently adopted and now requires that Arc Fault Detection and Interruption (AFCI) devices monitor and protect PV systems in the event of an arc fault and that Rapid Shutdown Circuit Interrupters enable firefighters to remotely interrupt and de-energize systems on demand. While the previous code required these devices specifically for PV systems located on structures, the 2014 NEC regulation now extends these requirements to apply to systems located in all areas on buildings and on the ground, such as in yards and parking lots.
