Module C — Live Schematic

Wiring Sandbox

Three progressive exercises on a live schematic. Land each conductor while the bench is dead, energize it, then operate the switches: the schematic shows voltage at every terminal and animates current along the path it actually takes. Miswire it and the hazard readout names what is live that shouldn't be — reversed polarity, a switched neutral, a hot on a traveler.

Land the three conductors, then energize the bench. A test lamp is plugged into the lower outlet — wire it right and it lights. Wire it wrong and the schematic tells you what's live that shouldn't be.

Wire it dead first — same as you would on site.

Select a conductor, then click a terminal to land it.

One conductor per terminal, click interaction (touch-friendly). Cleared circuits count toward the Bench Certified badge. Roadmap: drag-drawn routing, 4-way switches, motor control ladders, and panel exercises.
