10) This relates to the unit of competency as a whole providing the range of contexts and conditions to which the performance criteria apply. It allows for different work environments and situations that will affect performance. This relates to the unit of competency as a whole providing the range of contexts and conditions to which the performance criteria apply. It allows for different work environments and situations that will affect performance. This Competency Standard Unit shall be demonstrated in the installation and maintenance of de-energised high voltage and low voltage underground polymeric cables and includes underground services, network infrastructure, the jointing, terminating and repair of cables. It encompasses working safely, visual inspections and mandatory and functional test procedures, identifying non-compliance defects and mandatory reporting requirements Test and recording equipment may include digital/analogue voltage detectors, multimeters, phase rotation testers, load testers, continuity testers, tong ammeters, cable identification and spiking equipment and insulation resistance testers. Testing procedures may include continuity, polarity, phase rotation, insulation resistance and voltage. Installation may include, the laying and connection of cables, connection of the cable to underground equipment, the fitting and connection of fuses or circuit breakers and the testing and commissioning of the cable. Maintenance may include the removal, repair and replacement of electrical equipment encompassing “like for like” and associated hardware as well as the termination and/or connection of this equipment according to requirements and the temporary installation of services and associated equipment. It also encompasses the identification of faults; the pre-commissioning tests involving the equipment/system and the interpretation of these tests against agreed specifications. Service includes the connection between the customers’ point of supply and the underground pillar/pit connection (single phase), underground pillar/pit connection (three phase) and or underground to overhead connection. Electrical equipment and associated hardware may include relevant transmission or distribution network; switchgear (e.g. reclosers, sectionalisers, drop-out fuses, disconnectors, isolators, air break switches, gas filled switches, fuse switches ); transformers (e.g. padmount, pole-mounted and mobile); reactors; fault indicators; regulators;; capacitors; relays (simple); mobile generators and surge arrestors; support brackets and the like. Jointing and terminating equipment and locations may include circuit breakers, contactors, mains connection boxes, links, fuses, disconnect boxes, ring main units, distribution fuse boxes, pad mount and ground transformers, chamber substations, LV switchboards, pillars/turrets, busbar/termination boxes, street lighting control points and street lighting columns. Jointing and terminating materials may include compound and resin filled boxes, polymeric tape materials, polymeric heat shrink materials, "slip-on" moulded components and pre-stretched polymeric materials, compression, welded and mechanical connectors. It does not include the energisation of equipment in a highly complex, interdependent and interconnected electricity supply network system, where the effects of unintended consequences on the system are high risk and appropriate personnel effect energisation.
