The training to become a plant mechanic (SHK) was restructured in 2016. To meet the requirements of the training profession, an examination is scheduled after two years of training, which reflects the current level of performance. This workbook offers you six projects to prepare for the journeyman examination part 1. Projects 1-5 cover the technological connections from learning fields 1 to 6. The starting point is a practical task that involves the creation and testing of a supply technology component. From this, theoretical questions are derived and presented in each project. Project 6 addresses the electrical engineering tasks, which are content-wise related to projects 1 to 5. The journeyman examination part 1 includes: the practical task, the situational technical discussion, and the written task (theoretical task). Overall, part 1 of the journeyman examination accounts for 30% of the total examination. By working on the projects, you will acquire the fundamentals for a successful examination execution.
