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 low voltage underground paper insulated cables and covers the jointing, terminating, repair and replacement of cables. Installation and Maintenance may include the repair and replacement of cables and associated hardware. Types of cables includes: Paper-Insulated which refers to LV solid paper insulated metal sheathed. Underground equipment may include 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 gear and street lighting columns. Test and recording equipment may include voltage detectors, tong ammeters, cable identification equipment, cable fault locating equipment and insulation resistance testers. Jointing and terminating materials may include compound and resin filled boxes, paper tape materials, polymeric tape materials, polymeric heat shrink materials, "slip-on" moulded components and pre-stretched polymeric materials, compression, mechanical, welded and solder lugs and ferrules. Jointing and terminating locations may include 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.
