OREGON JOURNEYMAN / RESIDENTIAL ELECTRICIAN LICENSURE

OREGON JOURNEYMAN / RESIDENTIAL ELECTRICIAN LICENSE Examination ExamFOCUS Study Notes & Review Questions 

In the US, almost all technical exams on electrical works are based on the NEC. However, the NEC book itself is a 1500+ pages mega size monster. You just won’t have the time and energy to go through and memorize everything in there. Even though the exam may allow you to use the code book, looking up a particular item can be very time consuming and you may run out of time real quick! This is why we come up with this study product – we provide you with essential knowledge and information that can be easily comprehended so that during the actual exam you won’t need to browse the code book for answering every single question!

In Oregon, it is the Building Codes Division of the DEPARTMENT OF CONSUMER AND BUSINESS SERVICES DCBS that administers electrician licensing. A Limited residential electrician LR can make electrical installations on one- and two-family or multifamily dwelling units not exceeding three floors above grade. He must work under the supervision, direction, and control of a general supervising electrician. A general journeyman electrician can make any electrical installation under the supervision, direction, and control of a general supervising electrician, or perform works that do not require supervision. During the three-year license period, a licensee must complete a minimum of 24 hours of approved continuing education. The OAR 918 division 282 deals specifically with these license types.

The Oregon Electrical Specialty Code adopted the NEC. There are Oregon amendments in these areas:

Egress from working spaces around electrical equipment
Multi-wire branch circuit requirements for grouping and handle ties
Requirements for GFCI and AFCI protection techniques
Lighting and receptacle requirements in dwellings
Requirements for raceways in wet locations
Weather resistant and tamper resistant receptacles
Requirements for electrified truck parking spaces

In any case, the examination requires that you have a working grasp of the National Electrical Code as well as the local laws and rules plus a basic level of electrical theory knowledge. The exam covers a wide range of fundamental topics but this study notes will focus on topics related to code compliance. There is no way you can pass the exam without having solid real world experience. Our notes give you knowledge, principles and concepts. To master the topics, you must be “in the field”. And you need to know how the experts get things done. To succeed in the exam, you also need to read as many reference books as possible. There is no single book that can cover everything!
