The Oregon licensing division does not publish a list of subjects covered in the exam like many other states. The button below will open a basic exam content study guide we have created to help you navigate the many references listed in the allowed books:
Authorized to install, maintain, and repair electrical systems associated with renewable energy technologies, including photovoltaic (solar), wind, and related energy systems, as defined by the Oregon Electrical Specialty Code (OESC). Work includes associated wiring, equipment, and interconnections specific to these systems.
Performs work in compliance with the NEC, Oregon amendments, and applicable laws and rules, and typically works under the supervision required by regulation. Work is limited to renewable energy systems and their related components.
This license does not permit unrestricted electrical work outside the renewable energy scope or general installation of standard power systems beyond what is directly associated with the renewable energy installation.
About reference(s) 8 above. These two books have the same function but there are differences; Reference 8a is more instructional, includes practice questions, explainations and limited calculation help, better for learning the code. Reference 8b has more dense/comprehensive indexing and focuses on multiple paths to the same topic, has minimal explanations, better for speed during exams and finding obscure or oddly-worded questions. We advise buying one or the other based on your needs and the info provided here.
NOTICE: OAR 918 references the National Electrical Safety Code (NESC). You do not need to study this code because it only applies to utility work.
