Circuit Trainers
Practice wiring industrial motor control circuits. Build it wrong, see it fail. Build it right, watch it work. Each trainer walks you through an animated lesson, guided wiring, and commissioning — then goes further with fault diagnosis, alternative wiring, or code-based sizing exercises.
Motor Starters
Start with a basic 3-wire start/stop circuit, then step up to a control transformer with NEC 430.72(C) fuse sizing. Both include fault diagnosis and a final comprehension test.
Jogging Circuits
Two approaches to motor jog control — a DPDT control relay and a selector switch. Learn why they exist, how they differ, and explore variations like pilot light indication and two-location circuits.
Reversing Circuits
Dual-contactor reversing for hoist applications. Wire the L1/L3 phase swap, electrical interlocks, and a standalone overload relay. Diagnose faults across forward and reverse paths.
Variable Frequency Drives
Wire and program a VFD from power connections through analog speed control, digital inputs, fault monitoring, and maintenance bypass circuits.
