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 Competency Standard Unit shall be demonstrated in relation to the installation and maintenance of de-energised high voltage underground polymeric cables and covers the jointing, terminating, repair and replacement of cables used in systems and circuits and the issuing/accepting of relevant permits. Underground equipment may include links, fuses, ring main units, distribution fuse boxes, pad mount and ground transformers, chamber substations and busbar/termination boxes. Test and recording equipment includes voltage detectors, cable identification equipment, cable spiking equipment and insulation resistance testers. Jointing and terminating materials include compound and resin filled boxes, polymeric tape materials, polymeric heat shrink materials, "slip-on" moulded components and pre-stretched polymeric materials, compression and mechanical connectors Jointing and terminating locations include circuit breakers, links, fuses, ring main units, distribution fuse boxes, pad mount and ground transformers, chamber substations and busbar/termination boxes. The following constants and variables included in the element/performance criteria in this unit are fully described in the Definitions Section 1 of this volume and form an integral part of the Range Statement of this unit: Appropriate and relevant persons (see Personnel) Appropriate authorities Appropriate work platform Assessing risk Assessment Authorisation Confined space Diagnostic, testing and restoration Documenting detail work events, record keeping and or storage of information Drawings and specifications Emergency Environmental and sustainable energy procedures Environmental legislation Environmental management documentation Established procedures Fall prevention Hazards Identifying hazards Inspect Legislation MSDS Notification.
