This is a parts and wire kit for the practical exam of the Class 1 Electrician's License. The parts should be complete. (A substitute switch is included because the double-pole switch is missing. See the photo.) The wire kit contains the remaining wires from a single-use kit for the Class 1 Electrician's License. I only solved some of the practice problems and practiced by making wiring kits and combining them, so I had quite a lot left over. (I didn't cut and strip the wires every time.) Therefore, depending on how you practice, you should have plenty. There is a full set of wires, but the remaining amounts of VVF 4-core and round cables, which were originally small, are limited. Also, I'm including wires that were used for practice. Please use these for practicing stripping the insulation of CVV and other wires. (I practiced repeatedly, stripping them short.) As a bonus, I'm also including Hozen electrician gloves. The Class 1 Electrician's License exam requires frequent use of an electrician's knife, so please use these to prevent accidents. In addition, I'm including a textbook for the theory and practical aspects. It's an old book, and there are many rough notes inside, so please consider this as a bonus. However, the core content doesn't change much every year, so you can get past questions from the Japan Electrical Testing Services Center and study using this book, which should be quite helpful. If you don't mind the condition, it's a good deal. Please refrain from purchasing if you are looking for a perfect product, as this is a used item. Thank you.
