Find the fault. Work the repair.

The lighting prototype models ideal circuit connectivity, instrument contact, tool ownership, cover/screw states and bounded movement. Its authored intermittent contact drives the lamp through the same circuit used for readings. Meter HOLD freezes the displayed observation and cannot earn fresh verification. Other modules retain their existing lesson scope and controls. Native equipment keeps its authored proportions; the lighting teaching props are enlarged for readability.

The lockout jobs play four authored equipment-room variants, graded by the same live–dead–live procedure: your lock points, a proved meter, six motor pairs and a second proof. The print shows what the labels say, which can be wrong; only instrument readings show the circuit, and the debrief compares the two after the job.

The hazard meter and its modes are game rules judged from what you did and knew, not from the hidden circuit. Leads in the A jack across a live source blow the meter fuse, and the meter stays out of service until the fuse is replaced and the meter is checked and proved again.

Flicker timing and injury outcomes are authored game effects. This does not calculate fault current, torque, arc energy, joint strength or injury probability. Qualified electrical review is pending.

A quiet tick tracer does not establish absence of voltage. The exercise keeps isolation, lockout and contact-meter verification separate, following the principles in OSHA 1910.333 and Fluke’s instrument verification guidance. The generic Blender meter has illustrative controls; use the actual instrument’s manual for field work.
