F432-005-2:2019

1. Introduction

This reviewed NOSS titled Single Phase Electrical Installation and Maintenance specify
the competencies required to perform activities such as single phase drawing, single
phase wiring, single phase system maintenance, single phase motor and single phase
motor control installation for electrical systems 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 2) named Single 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 Single 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 2 Single 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-320-2:2012 Single 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 Single 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

2 / 62

F432-005-2:2019

specific skills that can be achieved through competency training programmes.
Hence, the reviewed of NOSS for Single Phase Electrical Installation and
Maintenance is very timely and even 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 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 such as electrical
appliances 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 Single Phase
Electrical Installation and Maintenance are illustrated in Figure 1 and Figure 2
respectively. Electrical installation components can be categorised into mechanical,
electrical, and electronic and instrumentation sub-groups. Single Phase Electrical
Installation and Maintenance operations include servicing of all these three sub-
groups of components. This NOSS covers the servicing of all these three categories
of components. Level 2 comprises both technical competencies to perform Single
Phase Electrical Installation and Maintenance operations and functions. The NOSS
title for Level 2 Single Phase Electrical Installation and Maintenance is as
highlighted.
