This is the U-CAN Second-Class Electrician's License Pass Guide Course textbook. It's from around 2012, but it's in new condition as the wiring diagrams, etc., haven't been opened. There are no markings in the textbook, and the video textbook is also unopened. Please judge the condition of the product from the photos. I bought this with the goal of getting the license, but I was too busy to study, so I hope it can be of use to someone.
