Keep this short explanation in mind when applying any bonding or grounding requirements of the NEC. PV system DC circuits must use one or more of the following system configurations [Sec. 690.41(A)]: (1) 2-wire circuits with one functionally grounded conductor.
Every three years, the National Fire Protection Association (NFPA) publishes an updated National Electrical Code (NEC). As electricians, journeymen, and PV installers are intimately aware, the details of this code are as ever-shifting as the energy industry itself. 690.31 (G) is a new section that includes requirements for PV system DC
As electrical related components and systems are a critical part of any solar energy system, those provisions of the National Electrical Code (NFPA 70) that are most directly related to solar energy systems have been extracted and reprinted in this International Solar Energy Provisions (ISEP). These electrical provisions have been organized in the same format as the ISEP chapters in
The most common code system designers, installers, and inspectors refer to for PV and ESS systems are NFPA 70, or the National Electrical Code (NEC). PV systems have requirements that span multiple Code articles, Rapid shutdown requirements were added to the NEC during the 2014 Code cycle. The intention of rapid shutdown is to protect
