This self-paced, 60 minute web-based training program provides PV module manufactures, installers, authorities having jurisdiction, and design professionals with the requirements found in NEC 690, Part II Circuit Requirements, for use with flat-plate photovoltaic modules, panels, and inverter systems to achieve safe, code compliant installations. All information presented in this module complies with the requirements in the 2011 version of The National Fire Protection Association, NFPA 70; better known as the National Electrical Code (NEC).
Upon completion of this program, participants will be able to understand the concepts of wire sizing and insulation characteristics for PV system installation, and be able to discuss how current calculations effect wire gauge and overcurrent protection. Participants will also be able to understand the effects of ambient temperature and wire routing methods on PV circuit design.
