Modular Design Electrical Training Workbench with Three-Phase Four-Wire Power Supply and Leakage Protection for Vocational Training

This electrical skill didactic workbench serves as vocational education teaching equipment for technical school laboratory training. The station consists of a training table, mesh plate, and training components, enabling students to arrange components according to training circuits and complete all installation and wiring themselves to simulate industrial environments.

The system provides comprehensive training in simulated operation, installation, and commissioning of machine tool circuits, motor control circuits, and lighting power distribution. It enhances students' hands-on skills and practical application abilities while also serving as a testing device for electrician certification exams.
