Hitachi Institute of Technology (HIT) is an educational institute of Hitachi, Ltd. focusing on technical education for employees of Hitachi Group. One of the reasons why electric world is not familiar is that many people do not have wiring experience. Even electric designers draw drawings, but outsource the wiring. In order to know how the electric circuits operate and how the circuit trouble is caused, it is necessary not only to understand the mechanism of the electric circuits but also to have wiring experience, that is “practical training”. While devising training equipment and textbooks, HIT has kept on basic training courses of electrical systems with emphasis on wiring and actual machine training for years. These training courses have had a good reputation from the trainees.
