Second-Class Electrician Examination Study Guide Question Book x 1 Basic Explanation Book x 1 Practical Exam Preparation, Full Color #1 - #13 Practical Wiring Answers and Completed Examples This is a set sale of two question books and practical exam preparation materials. I passed with this, so how about it for those starting out? The practical text is full color and has a volume that would cost over 6,000 yen to copy at a convenience store. It's easy to understand because it's a full-color set of wiring diagrams and completed examples.
