Elements and Performance Criteria

1. Prepare to select power factor correction equipment
   • Scope of the electrical installation is determined from job specifications and/or appropriate person/s
2. Work health and safety (WHS)/occupational health and safety (OHS) electrical installation requirements and relevant industry standards are identified and applied
3. Cable routes, route lengths of cables and conditions of the wiring system for operation are determined from job specifications and/or appropriate person/s
4. Select power factor correction equipment
   • Wiring systems are selected for suitability of the environments
5. Cable conductor sizes are selected for current-carrying capacity requirements, voltage-drop and earth fault-loop impedance limitations
6. Circuit protective devices are selected to meet job specifications for coordination with conductor current-carrying capacity
7. Earthing system components are selected for the multiple earth neutral (MEN) system
8. Evidence of the electrical equipment selected is obtained in accordance with WHS/OHS safety requirements
9. Complete documentation
   • Evidence from manufacturer/supplier of the selected electrical equipment is obtained in accordance with WHS/OHS safety requirements
10. Selection justification and calculations are documented in accordance with workplace procedures
11. Electrical installation arrangement and manufacturer specifications for selected items are documented in accordance with workplace procedures and forwarded to appropriate person/s

Range Statement

Range is restricted to essential operating conditions and any other variables essential to the work environment. Non-essential conditions may be found in the UEE Electrotechnology Training Package Companion Volume Implementation Guide.
Selecting power factor correction equipment must include at least two different power factor installations from the following:	LV installation using contactor switching LV installation using solid-state switching high voltage (HV) installation using contactor switching HV installation using solid-state switching
