Listen and confirm the brief: Confirm equipment, work scope, and authorization; ask when anything is unclear.
Report a fault with evidence: Organize location, symptom, evidence, uncertainty, and reporting in English.
Identify tools and clarify the request: Identify the requested tool and confirm the handover; possession does not authorize testing.

Safety and Tools

Build stop points, de-energizing habits, verification habits, and tool recognition first.

Why Electricity Is Dangerous: Use shock, short circuits, fire, and arc flash to build the first rule: invisible electricity must be proven absent.
De-energize, Test, Lockout/Tagout: Turn safety into repeatable actions: identify sources, isolate, lock, verify, and maintain control.
Multimeter Basics: Use a dead receptacle case to understand voltage, continuity, and resistance measurements and their limits.

Circuit Fundamentals

Clarify voltage, current, power, hot/neutral/ground, and complete circuit paths.

Voltage, Current, Resistance, and Power: Turn formulas into intuition: voltage pushes, current flows, resistance limits, and power becomes heat or work.
Hot, Neutral, and Ground: Explain hot, neutral, and ground as circuit paths, and why neutral-ground mistakes are dangerous.
Series, Parallel, Loads, and Voltage Drop: Understand why residential loads are usually parallel, and why voltage drop or loose connections cause symptoms.

Residential Devices

Recognize breakers, GFCI devices, receptacles, switches, conductors, and boxes.

Breakers, GFCI, AFCI, and Panels: Recognize what common protective devices do and do not protect, and what trips tell you.
Receptacles, Switches, and Lighting Logic: Do not memorize diagrams blindly; understand incoming power, outgoing load, and what the switch controls.
Wire Gauge, Color, Termination, and Box Space: Understand how ampacity, color identification, termination quality, and box space affect safety.

Practical Workflows

Use earlier concepts to understand common work and troubleshooting workflows.

Safe Receptacle Replacement Workflow: Use a simulated workflow to connect tools, de-energizing, verification, colors, termination, GFCI, and final checks.
Single-pole Switch Troubleshooting: Use dead lights, ineffective switches, and multi-wire boxes to practice circuit-based troubleshooting.
Common Fault Troubleshooting Map: Put dead circuits, trips, heat, and miswiring into one decision map that reviews the first 11 lessons.

A study question to try

Using this material, explain three key terms in English and Chinese, then give me one comprehension question. Keep the original sources, jurisdiction limits and stop-work conditions. Say when the material does not answer something. Do not provide live electrical work instructions.
