Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

ICTTEN201 - Use electrical skills in telecommunications work

What evidence can you provide to prove your understanding of each of the following citeria?

Connect up, test and verify DC and AC circuitry

  1. Identify any hazards and work health and safety (WHS) issues for a safe work site, and notify appropriate personnel
  2. Connect a series and a parallel DC and AC circuit configuration following safe work practices
  3. Choose appropriate test equipment and measure values of electrical quantities of circuits
  4. Use calculations to verify measured values of electrical quantities in a series and in a parallel circuit configuration
  5. Compare measured values to calculated values, and determine reasons for any variations
  6. Measure low voltage (LV), extra low voltage (ELV) or telecommunications network voltage (TNV) to determine if values are within equipment or power supply specifications
  7. Use appropriate test equipment to measure AC voltage (multimeter) or AC current (clamp meter) in a safe manner that does not require an LV circuit to be disconnected
  8. Test residual current devices (RCD) or earth leakage devices to ensure they are operational prior to working with AC mains powered equipment, power supplies and tools
  9. Evaluate results and determine probable faults, if relevant
