Wireman and chargeman certificates in Malaysia (2026): PW2, PW4, A0 to B4, how to qualify and what the work pays

Electrical competency in Peninsular Malaysia comes in two separate ladders from Suruhanjaya Tenaga (ST, the Energy Commission). Wiremen (pendawai, PW1 to PW6) wire buildings and sign off the wiring. Chargemen (penjaga jentera elektrik, A0 to B4) operate and take charge of electrical installations such as factories, buildings and substations. Neither certificate comes from a short course. For a PW2, the usual home-wiring grade, you need to have finished Form 5. If you’re already working, you also need two years’ wiring experience with an ST-registered electrical contractor, recorded in a logbook; then you take an accredited part-time course, often about six months, and pass ST’s theory, practical and oral exams. School leavers can instead do a full-time programme of about two years at an accredited centre.

This guide covers what Malaysian electricians, trainees and employers ask about this in the main wiremen’s and chargemen’s Facebook groups. Every rule is checked against the Electricity Regulations 1994 and ST’s current guidelines. Pay and fee figures are what people in those groups report, with the date and place where they gave one. They aren’t survey data.

If you’re a homeowner trying to work out who can do your job, start with the short version. For house wiring and a DB change, you want a PW2 or PW4 wireman who works for a registered contractor. A chargeman grade on its own isn’t a wiring qualification.

What each grade lets you do

ST’s Arahan 12/2026 (May 2026) sets out each grade and what it covers:

The testing endorsement is the part that matters for a house. Under the Electricity Regulations 1994, wiring for a single-phase supply has to be done under the “immediate supervision” of a wireman, who certifies the completion form. Then a wireman authorised to test it signs the test certificate (regulations 12 and 13). A three-phase supply needs a three-phase wireman. And regulation 12(3) says the wireman doing this must be employed full-time by an electrical contractor or a private wiring unit.

A chargeman’s job is to work, operate or be in control of an installation, and to issue permits to work (written instructions that must be in place before anyone under them starts work on the equipment). In ST’s chargeman guideline (March 2026), that’s the whole of the role. Chargemen don’t certify wiring, and the monthly inspection visits are done by a competent electrical engineer or electrical supervisor, not by the chargeman. Owners of installations rated 100A and above must appoint a competent person. That’s where most chargeman jobs come from: factories, malls, office towers, hospitals, data centres and solar farms.

Questions in the groups often say “G2 wiring course”. G1 and G2 are Sarawak’s wireman grades (G2 is single-phase, G1 three-phase), issued by the state’s Electrical Inspectorate Unit. Peninsular Malaysia and Labuan use ST’s PW grades, and Sabah has had its own regulator, the Energy Commission of Sabah (ECoS), since 2024.

How to get a PW2, and then PW4

ST’s wireman exam guideline sets these conditions for PW1 and PW2:

• Malaysian citizen, at least 18.
• Finished Form 5 (tamat tingkatan lima). Group members often say “you need SPM”. One practitioner correctly pointed out that the condition is completing Form 5, not passing SPM.
• Two years’ wiring experience with an electrical contractor or private wiring unit registered with ST, backed by a complete logbook. For part-time courses, the logbook has to be verified by a competent person and by your employer, and you show EPF or PERKESO statements as proof of the two years.
• Able to speak and write Malay, and know first aid and electric-shock treatment.

That experience condition trips up a lot of people. A recurring question comes from wiremen with years of experience whose employer isn’t registered with ST, or never paid their EPF and SOCSO. Experience with an unregistered company doesn’t meet ST’s condition for the part-time route. ST’s flow chart does allow one alternative: two years shown by a testimonial letter from a registered contractor that subcontracted work to you, plus a logbook. Otherwise, members suggest moving to a registered contractor and building the logbook there, taking a full-time programme, or getting SKM first.

Full-time programmes are open only to people who aren’t working, according to ST’s own course page. They run Monday to Friday and take about two years for single-phase. For school leavers they’re the usual route, through GIATMARA, the Human Resources Ministry’s industrial training institutes (ILP), the youth ministry’s skills institutes (IKBN and IKTBN), ABM (the construction board’s academy) or MARA’s TVET colleges. Some programmes go up to PW4 or chargeman grades. Members report small allowances for full-time trainees: about RM150 a month at ABM (more during the industrial placement), RM200 at GIATMARA.

SKM shortcut. If you hold SKM Level 2 (the national skills certificate), and have worked a year for a registered contractor after holding it for a year, ST exempts you from the theory, practical and oral exams. You’re awarded PW1. To get the testing endorsement and PW2, you sit the oral (testing) exam. Group members warn that an SKM earned through PPT, the recognition-of-prior-experience route, doesn’t work for this exemption because ST wants the SKM transcript. We couldn’t confirm that with ST, so ask your institution before relying on it.

PW4 needs PW1 or PW2 held for at least a year from its issue date (and registered with ST), plus a year’s three-phase wiring experience with a registered contractor (ST’s part-time course page specifies a Class C contractor). Alternatively, three years’ wiring experience can take you straight to the three-phase exam. Pass PW3 while holding PW2 and you get PW4 once the endorsement fee is paid. In part-time courses you can’t skip PW2; several replies make that clear.

The exam has three parts: theory, practical and oral (lisan). You must pass all three. If you fail one, you resit only that part, except that failing the practical means redoing the practical and the oral. ST’s PDF lists RM50 for the exam plus RM50 for the testing endorsement. The fee schedule in the regulations (as consolidated to 2014) says RM60 each, plus RM20 processing. Check with your centre.

Age. People ask whether 35, 43 or 50 is too old. It isn’t. There’s a minimum age and no maximum for sitting. Members describe someone taking A0 part-time at nearly 55 and doing PW2, PW4 and A1 part-time, the last at 51. A former soldier who took PW1 in 1999 and A4 after retiring had B0 11kV by 2024. Some full-time programmes and their fee assistance have age limits, but part-time courses generally don’t. The regulations stop chargemen and wiremen working under their certificates after 65, unless ST waives that year by year with medical evidence.

Courses, time and cost

ST lists accredited centres on its website. In October 2026 it had 126 centres. PW2 was offered full-time at 100 of them and part-time at 55; PW4 at 46 full-time and 41 part-time. Chargeman A0 was at 22 and 29, and B0 and above at only a handful. More than half of the centres are GIATMARA branches. The rest are mainly ILP, MARA colleges, IKBN/IKTBN, ABM and state skills centres. The list has no addresses, so search the centre’s name.

Part-time classes run at weekends or on weekday evenings. Colleges advertise PW2 and PW4 part-time as about 240 hours over roughly six months (Pahang Skills, STDC Kuala Selangor). None of the centres we checked publish fees, and ST leaves fees to the institutions. In the groups, one wireman put part-time PW2-to-PW4 fees at “RM1,800 to just over RM2,000 depending on where you study”, and a chargeman suggested having about RM3,000 ready for part-time chargeman classes. Ask for the full cost including exam and registration fees.

Two-day and three-day “wiring courses”, including community college short courses and private trainers’ classes, teach skills but don’t lead to an ST certificate, as experienced members point out when someone asks. The same goes for the 11kV switching workshops advertised in the chargeman groups, including those preparing engineers for the competent electrical engineer (JEK) interview. They’re useful practice, not an exam route.

The chargeman ladder

The chargeman guideline asks for:

• Malaysian citizen, at least 20, Form 5 (the vocational college certificate, SVM, is considered with a four-semester transcript).
• Three years’ experience working where electrical equipment is operated, including controlling live equipment. A wireman certificate or a polytechnic electrical certificate cuts that to two years.
• Every certificate you already hold must have been registered with ST for at least a year before you apply. This explains a common complaint: “my B0 application was rejected because my A4 isn’t registered”.

From A0 you climb by experience or by 80-hour modules at accredited centres. A0 to A1 takes a year on low-voltage overhead lines, or the overhead-line module (TAVR). A1 to A4 takes a year of generator synchronising, or the synchronising module. You can also go from A0 straight to A4 with both. B0 needs two years on high-voltage (11kV or 33kV) systems, after holding A4 registered for two years. B1 and B4 follow the same pattern for high-voltage overhead lines and generation.

A Penang MARA college laid out the fastest route in its own post. Three years studying for chargeman A1 from 18 to 20, a year for A4, two compulsory years working on 11kV or above, then B0 11kV at about 26 (five months full-time or ten part-time). The same post says that in the past most people only reached this level in their 30s to 50s.

Another dilemma: an employer offers to sponsor a restricted B0 (B0 terhad, valid only for that site) for an A4 holder. The advice split. Some said take it for the high-voltage experience and the logbook, then sit B0 open later. Others warned that companies use it to get high-voltage cover at A4 pay, and said not to accept unless the pay matches B0. One member on a restricted B0 reported a RM6,500 basic plus 60 to 70 hours of overtime a month.

Registration, renewal and the new competency points

Passing the exam isn’t the end of it. A certificate only lets you work once it’s registered with ST (through ST’s online system, eCOS) by the employer or the installation you work for. You can register for 1 to 5 years. The regulations’ fees per year (as consolidated to 2014) are RM30 for a single-phase wireman, RM40 for three-phase, RM60 for a low-voltage chargeman and RM110 for 11kV and 33kV. The key rule is regulation 63(3): you may not register a certificate “with more than one employer or installation, except with the written permission of the Commission”. ST considers written applications under a May 2025 guideline, written mainly with solar farms in mind; a mix of electrical and solar sites is capped at three of each.

To leave an employer, members describe filing a resignation notice against your certificate number in eCOS and emailing the letter to ST. A lost certificate is replaced on a statutory declaration plus a fee (RM110 for a wireman, RM220 for a chargeman in the fee schedule).

Competency points (ECP). In May 2026, a post claiming that chargemen would soon need points to renew drew about 125 comments, most of them angry about the cost: the pilot courses were RM700 for 4 hours and RM1,000 for 8 hours, against A0 pay members put at RM1,700 (starting) to RM2,800. Here’s what ST’s letter of 12 May 2026 actually said. ST was running pilot courses under its new ST Energy Competency Excellence (ST-ECE) programme. A points system “akan diwajibkan pada masa hadapan” (will be made compulsory in future) for renewing competent-person registration, with the rules “to be announced later”. Attendees of the pilot earn 10 points to use once that renewal guideline takes effect. By October 2026, ST hadn’t published a guideline making points compulsory. A minority welcomed continuing training but objected to the price or to ST running it. One chargeman suggested points should come from logged switching and permit-to-work activity rather than generic courses.

What the work pays

There’s no published salary survey for wiremen or chargemen. These are figures people gave in the groups in 2026. They’re anecdotes, and some comments in salary threads are plainly jokes or boasts. The statutory minimum wage is RM1,700 a month, about RM65 a day over a six-day week.

Wiring work, daily rates. A February 2026 post asked why wiremen with four or five years’ experience still work for “RM100++ a day”. An October 2026 post complained that contractors who charge high project prices still pay skilled workers only RM70 to RM80 a day. A helper’s day rate in a March 2026 quote was RM80. One member recalled earning RM40 a day in 2011.

Salaried wiremen. A PW4 with seven years’ experience in a town (January 2026) asked what basic to expect. Replies clustered around RM2,700 to RM3,000, about RM3,500 with solar skills, and one said RM5,000. One gave a rough scale of RM1,700 for a PW2 with SPM and RM2,200 for a PW4 with a diploma. A site supervisor for a contractor said he gets a RM4,000 basic and about RM8,000 with project bonuses, without SPM or a diploma. Data centres pay more: a PW4 technician starting at “4.5k”, and a local PW4 on a RM4,200 basic at a Bukit Jalil data centre.

Chargemen. A January 2026 “market rate” post said A0/A1 RM3,000, A4 RM5,000 to RM6,500, B0 11kV RM9,000 to RM12,000, B0 33kV RM15,000 to RM20,000 and B4 33kV RM18,000 to RM25,000. It was a call to defend rates, not a survey. Figures from individual members were mostly lower:

Running your own wiring business. A 273-comment thread asked why experienced wiremen don’t become tokey (boss). The top answer, with 219 reactions, put it plainly: being good at the work isn’t the same as being able to run a business. That means finding customers, quoting accurately, managing cashflow and workers, and absorbing losses. One self-employed wireman described RM6,000 to RM8,000 a month after about ten years, and another RM600 days in the week before Raya. Others described customers who never paid the balance, months without jobs, and constant undercutting. Several made a distinction between being self-employed and running a contractor company. To register as an electrical contractor, you need a full-time wireman of the right grade (yourself counts), SOCSO cover and testing equipment. A Class D contractor (jobs up to RM100,000) needs one single-phase wireman. Class C (up to RM500,000) needs a three-phase wireman with the testing endorsement. Our house wiring prices guide covers what wiremen charge customers.

TNB jobs. Someone aged 35 with wiring and aircond experience but no certificate asked what TNB’s breakdown crews hold. The thread drew about 200 replies. The consensus was that TNB’s technical posts now ask for at least chargeman A1, with an age limit around 30 for junior technician posts, and that a diploma helps. Members said ILSAS is TNB’s in-house training institute for staff, not a way in. Many “TNB only hires relatives” comments were rebutted by staff who got in without connections. We didn’t find a current TNB advert to confirm the requirements. Working for TNB’s contractors was the common alternative, with round-the-clock standby and plenty of overtime.

Renting out a certificate (sewa or gantung lesen)

The groups are full of posts like “PW4 untuk digantung” and “berapa rate sewa A1 sekarang?”. The rates members quoted in 2026: about RM200 a month for PW2, RM300 to RM850 for PW4 (RM400 to RM500 most often), and A1 between RM200 (called too cheap) and RM600. Contractors want these certificates because ST registration requires full-time wiremen by class (regulations 76 and 78). Installations of 100A and above also need a registered competent person.

The regulations don’t allow it, for three reasons:

• The wireman who supervises and certifies wiring must be employed full-time by the contractor (regulation 12(3)), and a contractor’s registration rests on wiremen it “employs on a full-time basis” (regulation 76).
• A certificate can’t be registered with more than one employer or installation without ST’s written permission (regulation 63(3)).
• Making “a false or fraudulent declaration, certification or representation” is serious misconduct that lets ST suspend or revoke the certificate (regulation 59). The general penalty for breaching the regulations is a fine of up to RM5,000, a year’s jail, or both. Working outside your grade’s scope breaches Arahan 12/2026, which carries up to RM200,000, two years’ jail, or both.

Experienced members put the practical side bluntly. “You can’t rent a licence, you can hire a licensed person.” If the company’s work is bad, “your licence is the first one they chase”. One A1 holder said the company stopped paying after three months, and he deregistered himself in eCOS. Another member found that a company had registered his PW4 in eCOS without any agreement and refused to cancel it. The advice split. The most-liked reply was a template letter denying any agreement, to send to the company and then to ST. Others said ST’s process is a resignation notice in eCOS plus a letter, while one warned that a resignation letter implies you were employed. Going to the ST office in person with the evidence was the common thread, and one added: make sure you haven’t accepted any money from the company.

The once-a-month chargeman. A newly qualified A4 asked whether he could take a building job paying RM4,500 that only wanted him on site once a month. Most replies joked about taking it themselves. The few serious ones split: one said it’s against the law “but don’t turn down the money”, others said take it but accept that you’re on call and carry the responsibility. The regulations don’t set daily hours for a chargeman. But the registration names you as the person who works, operates or controls that installation, and the monthly inspection visit is an engineer’s duty, not yours. ST’s own May 2025 guidance says that even for installations used only part-time, the competent person “perlu berada di pepasangan elektrik tersebut sepanjang masa sekiranya premis digunakan”: must be there whenever the premises are in use. A once-a-month chargeman is registered for a role they aren’t doing, and the certificate carries the risk if something goes wrong.

Foreign workers and wiring

Only Malaysian citizens can sit ST’s wireman and chargeman exams. Foreigners can get only a temporary certificate of up to 12 months, and only with recognised qualifications, needed expertise and a work permit (regulation 52). A 78-comment thread about foreign workers reached a working consensus. With a valid permit they can work as helpers, pulling cable, trenching, hacking walls for conduit and working in manholes, under a wireman’s supervision. Terminations and DB or switchboard work should be done or checked by the PW2 or PW4 who signs the job. The regulations require “immediate supervision” by the wireman, not a particular nationality for the helper. A vocal minority said foreigners shouldn’t wire at all, and many members described poor work by foreign crews (no earth wire, cable colour codes ignored, government buildings that ended up being rewired). One member added that on large projects like data centres, foreign crews do much of the work under local supervisors.

Before you start

• Check your employer’s ST registration before counting your experience, and keep your logbook signed as you go. Members warn that logbooks and procedures get harder the longer you leave them.
• For part-time study, collect your EPF or PERKESO statements and an employer support letter. These are on ST’s application form.
• Get each certificate registered by your employer promptly. For PW4 you need PW1 or PW2 held for a year and registered; for chargeman grades the one- or two-year wait counts from registration.
• If someone asks to “use” your certificate, remember who signs and who gets investigated. If a company registers it without your agreement, go to ST.

ST’s public register lists currently registered competent persons. In early October 2026 it had about 47,800 registrations. The biggest groups were PW4 (about 14,900), chargemen A0 (6,900), A1 (6,100) and A4 (5,900), and PW2 (5,300). Homeowners can check a wireman’s grade there. Our Johor Bahru electricians guide shows how to use it alongside where tradespeople actually advertise.
