ICTCBL4002B
Prepare design drawings and specification for a cable installation

This unit describes the performance outcomes, skills and knowledge required to prepare design drawings and specification for a cable installation.Cable used must be compliant with appropriate Australian Communications and Media Authority (ACMA) technical standard requirements (e.g. for underground, aerial, Category 5, 6, 6A, 7 or 7A, or unshielded twisted pairs (UTP)).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: determine installation options produce amended schematic and floor plan drawings produce amended specifications verify specifications with customer.
Context of, and specific resources for assessment	Assessment must ensure: sites where cable installation may be conducted use of equipment currently used in industry relevant regulations, company policies and cabling specifications that impact on cable 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 oral or written questioning to assess knowledge of installation options direct observation of the candidate assessing installation requirements review of design drawings and specification for a cable installation, including costings prepared by the candidate.
Guidance information for assessment	Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example: ICTCBL4004B Schedule and supply cabling installation. 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.
