How to be a Wireman (Part 1)

As stated in Electricity Regulations 1994, the Wireman eligibility is based on Regulation 50 which state, to sit for the examination for a Certificate of Competency as a Wireman (based on Suruhanjaya Tenaga website):

1.1 Single-Phase Wireman (Private Candidates)

  • Applications to sit for the Competency Examination for Single-Phase Wireman should be done using Form ST (PE)1 Amendment 2003.
  • Qualifications are as stated in Regulation 50, Electricity Regulations 1994 and Electricity Regulations (Amended) 2003.
  • The minimum academic qualifications 50(1c) has been set at Form 3 in a government assisted school or passed Peperiksaan Menengah Rendah (PMR) certification or equivalent.
  • Applicants who possess a MLVK (Electrician) Certificate/mid-level SRM and have interned for 6 months with an Electrical Contractor and have a complete log book are exempted from taking the theory, practical and oral examination.
  • Candidates who are qualified will only be awarded a Certificate of Competency as Single-Phase Wireman without Endorsement for installation testing. However, any candidate who intends to obtain the Wireman Certification with Endorsement is required to take the oral examination. If they fail the oral examination, certification will only be given for Wireman without Endorsement for installation testing.
  • Candidates who are interested in taking the Wireman Examination with Endorsement for installation testing will have to pay both the Examination fees and the Endorsement Examination fees.
  • Candidates with the MLVK Certificate(Intermediate Level) or Malaysian Skill Certificate (Level Two) and have working experience of not less than 6 months with a registered electrical contractor are eligible to apply for PW1 Wireman Certification, without sitting for the theory and practical component of the Wireman Examination. However, this exemption does not include MLVK/SKM Certificate holders who obtained their certificates through the Accreditation of Prior Achievement (APA).
