The image is a series of diagrams illustrating different types of electrical wiring connections, specifically focusing on grounding methods. It includes eight different configurations, each labeled with Japanese text explaining the type of connection and its purpose. The diagrams show various components like wires, connectors, and grounding points, with detailed annotations. The post text in Japanese translates to "The number one thing that is essential in exams but useless in the field." This suggests that while these diagrams are crucial for theoretical understanding and passing exams, they might not be as practical in real-world electrical work scenarios.
