book will aid the electrician when the electrical inspector cites a
violation. The electrical inspector should always give the reference
section, preferably in writing, for any correction they request. If the
inspector cannot cite the reference section of the Code, they should
not cite the installation.
An excellent workbook to understand the correct wiring of a branch
circuit with the student tested on, is it a correct installation or a
violation of the Code along with exams and detailed answers.
book was written for the electrician wiring a residence following the
minimum safety standards of the National Electrical Code. The exams are
written the way the license exam should be written requesting the Code
section to be written prior to selecting a choice of answers. The Code
should always be referenced directly to make sure. When the Code is
referenced, it is a good idea to record the section number in the Code
book. This is referred to as "citing the Code reference." By citing the
Code section, it will eliminate guessing at the multiple choice of
answers the day of the exam.
