TradeRig was built to give apprentices more opportunities to practise electrical diagnosis. Instead of waiting for limited lab time, learners can build circuits, inject faults, test with virtual tools, and repeat the process until the reasoning becomes familiar.
Physical rigs remain essential, but they are expensive, shared, and available for limited periods. Learners often get only a few attempts at the exact diagnostic process the job depends on.
TradeRig gives them more opportunities to build circuits, introduce faults, test with virtual tools, and follow the evidence to the cause before working on real equipment.
"You don't learn fault-finding by reading about it. You learn it by finding faults, over and over, until the reasoning is automatic."
TradeRig is built around repeated diagnostic practice. Learners build circuits, introduce faults, test with virtual tools, and follow the evidence to the cause. DC Electrical Diagnostics provides the technical training, while Safety is included with every paid plan.
Every feature is designed to strengthen practical diagnostic reasoning through repeated, guided use.
DC Electrical Diagnostics follows one clear workflow: build, fault, test, diagnose, and verify.
Designed for electrical apprentices, trade students, and working technicians who want more practice finding faults.
TradeRig helps learners build stronger troubleshooting habits before they work on live equipment, with progress they can see across repeated attempts.
