Recommended Prerequisites: This course is suitable for journeymen and all electrician trainees with the prerequisite experience. Prerequisites include completion of Get Wired! 101-102 or equivalent, basic experience with series and parallel connections, series and parallel basic calculations, proficiency with the NEC (National Electrical Code), and at least 6 months of on-the-job experience.
This course introduces the electrician trainee and journeyperson to the basics of electrical code compliance when installing solar photovoltaic systems. The course will explore Article 690 - Solar Photovoltaic (PV) Systems of the NEC using an exciting set of 360° images, photographs, illustrations, and diagrams. An interactive installation simulation, a solar connector wiring lab, and application of the requirements of Article 690 are also included.
This exploration will focus on the PV array and PV array wiring methods leading up to the inverter and system disconnect. The course is only focused on NEC compliance with electrical equipment and wiring methods involved with building the module interconnections, source circuits, output circuits, and raceway systems needed to complete the wiring of an AC or DC array.
Next, an analysis of the three photovoltaic technologies discussed by Article 690 that are presently used and their basic wiring patterns. PV source circuit wire sizing for voltage drop, ampacity, pairing with overcurrent protection, and temperature follows the introduction modules. This includes site survey parameters for wire installations and for choosing the correct free air and raceway methods for an array based upon its location.
Then, an introduction to basic solar electrical equipment installation from where to mount inverters, disconnects, combiners, solar connectors, and more. The topics chosen for the introduction address issues relate to worker safety, common inspection failures, electrical troubleshooting issues, and electrical fires.
