Tools and Employability Skills
Domain 14: Tools and Employability Skills
This domain tests correct tool selection and the workplace skills needed for consumer-facing metering work.
Core rules
- Common tools are insulated screwdrivers, combination pliers, side cutters, crimping tool, wire stripper, phase tester, multimeter, clamp meter, insulation tester and torque wrench.
- Use a clamp meter for load current without breaking the circuit; use a multimeter for voltage, continuity and resistance.
- Use a meter test bench and standard meter for calibration; keep instruments within calibration validity.
- Employability skills include clear communication, job cards, documentation, customer handling, teamwork, digital literacy and 5S housekeeping.
- Report unsafe conditions and incomplete work; never conceal a bypass or tamper.
Worked example
To check whether a 2 kW load is drawing the expected current, clamp the meter around the phase conductor with the load on. If the clamp reads about 8.7 A at 230 V, the load is normal. If it reads zero with the load on, check the circuit and meter connection. Reasoning: select a non-invasive tool first, then interpret current against calculated expectation.
Traps that cost marks
- Using a phase tester as a multimeter.
- Selecting a tool below the voltage rating.
- Over-tightening terminals.
- Issuing a bill without a job card.
- Poor customer explanation that triggers a complaint.
