ICTCBL2012B
Install functional and protective telecommunications earthing system

This unit describes the performance outcomes, skills and knowledge required to install telecommunications earthing system to metallic frames.Assessment by a TITAB registered assessor is recommended.Licensing, legislative, regulatory and certification requirements apply to telecommunications earthing systems.The six unit competency set ICTCBL2005B , ICTCBL2006B , ICTCBL2008B , ICTCBL2012B , ICTCBL2017B and ICTCMP2022B . that meets the Australian Communications and Media Authority’s (ACMA) requirements for Cabling Provider Registration (CPR), is generally used as part of a more specialised customer cabling qualification. This set is usually regarded as more suitable for new entrants where limited industry experience has been obtained and forms the major part of specialised qualifications such as ICT20313 Certificate II in Telecommunications Cabling. When these six units are undertaken as a set within state and territory funding approved programs, the two benchmark CPR units (ICTCBL2136B and ICTCBL2137B ) are not required.All customer cabling work in the telecommunications, fire, security and data industries must be performed by a registered cabler. All cablers are required to register with an ACMA-accredited registrar.

Evidence Required

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment
Critical aspects for assessment and evidence required to demonstrate competency in this unit	Evidence of the ability to: evaluate earthing needs for cable systems on customer premises and apply related OHS requirements determine potential earthing locations determine earth route and support system install functional earth installations including equi-potential bonding test and label earth installation manage remote power feed services.
Context of, and specific resources for assessment	Assessment must ensure: sites where installation of functional and protective telecommunications earthing system may be conducted use of testing equipment currently used in industry relevant regulatory and equipment documentation that impact on installation activities.
Methods of assessment	A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit: review of a hands-on project completed by the candidate review of an oral and written report with completed documentation, such as test results, updated cable plans and records direct observation of the candidate installing a functional and protective telecommunications earthing system.
Guidance information for assessment	Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example: ICTCMP2022B Organise and monitor cabling to ensure compliance with regulatory and industry standards. Aboriginal people and other people from a non-English speaking background may have second language issues. Access must be provided to appropriate learning and assessment support when required. Assessment processes and techniques must be culturally appropriate, and appropriate to the oral communication skill level, and language and literacy capacity of the candidate and the work being performed. In all cases where practical assessment is used it will be combined with targeted questioning to assess required knowledge. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. Where applicable, physical resources should include equipment modified for people with special needs.

Range Statement

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance.
