F432-005-3:2019 1 / 95 STANDARD PRACTICE NATIONAL OCCUPATIONAL SKILLS STANDARD (NOSS) FOR: THREE PHASE ELECTRICAL INSTALLATION AND MAINTENANCE LEVEL 3
F432-005-3:2019 2 / 95 1. Introduction This reviewed NOSS titled Three Phase Electrical Installation and Maintenance specify the competencies required to perform activities within domestic, industrial and commercial premises. This NOSS can be used by industries as a reference and guidelines for job description, performance appraisal and personnel development. Training centres could also employ this document as the programme curriculum for Malaysian Skills Certificate (Level 3) named Three Phase Electrical Installation and Maintenance. During a local conference that was held back in 2014 in Istana Hotel, Kuala Lumpur, the invited speaker from the Energy Commission of Malaysia (EC) has shared an important information to the participants about the statistics on competency as at December 2013. The statistic showed the estimated number of competent persons required based on number and type of installations are 147,270 persons and the number of competency certificate issued are 101,240 persons. This statistic has revealed a worrying scenario whereby there are shortage of competent person in Malaysia by 46,033 persons. Today, it has been 5 years after the statistic is revealed and surely the requirements of competent persons are increasing, and it is wondered if the EC has been able to meet its target. Most importantly based on training institution feedbacks, there is also an urgency to review the existing NOSS in order to suit the current needs of the industry. 1.1 Occupation Overview The Three Phase Electrical Installation and Maintenance industries are multi-million industries which involving various sectors such as oil and gas, construction, transportation, services, consultations and energy. Most of this industry has huge potential and impacts for significant growth as Malaysia is actively moving towards achieving Industrial Revolution 4.0 (IR 4.0). The Level 3 Three Phase Electrical Installation and Maintenance personnel are responsible for the continuous operation of electrical systems. They conducted site visit, monitoring electrical systems condition, performed maintenance and test electrical installation. Their invaluable experience and expertise are a huge advantage when an electrical system is to be established in any premises. 1.2 Rationale of NOSS Development This is a revision of NOSS namely EE-320-3:2012 Three Phase Electrical Installation & Maintenance. The process of revision inclusive of mapping the NOSS to compare and identify competencies relevant to the current industry needs. As the demand for Three Phase Electrical Installation and Maintenance continue to grow in Malaysia, there will be a need for highly skilled and competent workforce. The development of highly skilled and competent workers in the industry is vital to ensure that the need of the sectors that the electrical services industry supports is met. Future workforce must be trained and equipped with the necessary industry specific skills that can be achieved through competency training programmes. Hence, the reviewed of NOSS for Three Phase Electrical Installation and Maintenance is very timely and even
F432-005-3:2019 3 / 95 indispensable as the standard will provides a basis for formal and systematic training as well as for certifying experienced personnel. Consensus regarding job analysis and job matrix were obtained from the panellists where thorough discussion and debates were conducted during several reviewing session. Among of the outcomes from the activities are a few competencies have been re-aligned to match and meet the current demand by the industries. This includes competencies on building automation systems, earthing systems, relevant software's and many more. The reviewed sessions also found out that those redundant and repeated CU which doesn't reflect to the level's definition by the Department of Skills Development (DSD) is amended and in fact obsolete or irrelevant competencies have been stroked out. In brief, this NOSS has taken into account several crucial and important points such as the introduction of future emerging competencies, the inculcation of "green" aspects, the incorporation of health and safety measures, the fulfilment of competent person attributes and as well as the compliance with relevant authorities and regulatory bodies. All of this consideration is believed to have a pivotal role towards the successfulness of this NOSS. 1.3 Rationale of Occupational Structure and Occupational Area Structure The Occupational Structure and Occupational Area Structure for Three Phase Electrical Installation and Maintenance are illustrated in Figure 1 and Figure 2 respectively.
