An electrical training simulator allows students to assemble electrical circuits, including motor control circuits, utilizing a variety of lab schematics. The electrical training simulator allows an instructor to induce faults into the student-assembled circuit, thereby requiring the student to apply troubleshooting skills utilizing the lab schematic and digital multimeter to analyze and locate the introduced fault in the circuit. Electrical components are fixedly attached to a component mounting plate. In one embodiment of the invention, the instructor introduces the faults through a fault control panel attached to the electrical training simulator, where the fault control panel is not within view of the student. In another embodiment, the faults may be introduced wirelessly through a remote controller.

A method is disclosed to ensure that components in a complex system are correctly connected together. In one embodiment, such a method provides a library of previous configurations of a system. The system includes multiple components connected together with cables. The method generates, from the library, instructions for assembling the system by connecting components of the system together with cables. The method receives feedback generated in the course of using the instructions to assemble the system and uses the feedback to refine the instructions.
