This one-day class will clearly explain and summarize the intent and application of the National Electrical Code relevant to photovoltaic (PV) solar electric systems and cover significant changes in the 2014 National Electric Code that pertain to PV systems. Because the photovoltaic industry is undergoing extremely rapid growth and new technologies are constantly being introduced to the market, Articles 690 and 705 of the National Electrical Code incorporate a large quantity of important changes. The primary focus requirements for conductor routing and labeling, fuse servicing and disconnects, and arc-fault protection devices. In addition, code-compliant wire sizing per Article 300, and transformerless inverter installation will be discussed and case studies presented. Although many licensed electrical contractors in North Carolina have not previously had experience with Solar PV systems, as the PV industry expands electrical contractors will be called on both to install systems and to service existing systems.
