In this paper is, a method for describing the practical knowledge possessed by electrical installation engineers as explicit knowledge was discussed. The author, who has 45 years of practical experience as an electrical installation engineer, selected himself as the subject of analysis and described himself using a qualitative research method ”auto-ethnography.” The author extracted the practical knowledge that he had acquired through practical work and self-learning, using the ”repertoire” that was advocated as the lifelong learning theory ”reflection practice” for professionals as an index. As a result, the author was able to systematize practical knowledge as a ”repertoire” and at the same time to present a visualization method using ”frame analysis” of practical knowledge.
