Additional explanation: In the case of the double-heading fitting, I attached 'A' only to the back in the beginning of my video. However, it is said that attaching 'A' to both sides is closer to the correct answer. Therefore, please keep this in mind and practice attaching 'A' to both sides of the double-heading fitting when you are practicing. Example 1) 25A x 20A Reducing Tee Example 2) 20A x 15A Bushing Example 3) 20A x 15A Reducer View all Edukang.com lectures at once: https://cafe.naver.com/jls3000/47287 Sponsor and join membership:    / @edukangtv   Purchase practice materials and tools: https://smartstore.naver.com/edukang/...
