FieldEx brings field service management and a computerised maintenance management system (CMMS) together for Malaysian electrical services contractors. Every client's substations, switchboards, relays, transformers, gensets and distribution boards get their own record, monthly chargeman visits and long test cycles run to schedule, readings are captured on site, and inspection reports and job sheets reach the owner within the deadline.

What FieldEx does for electrical services contractors in Malaysia

An electrical services contractor in Malaysia works to the clock set by Suruhanjaya Tenaga (ST): monthly visits by the competent person, a report within 2 weeks, a relay test every 2 years and an installation test every five. FieldEx keeps every one of those dates on the installation it belongs to, with the readings and reports beside it. Book a demo to see it with your own installations.

Each installation and its equipment

One site per client installation, with its address, map pin, person in charge, service zone and registration details.
One asset per substation, high-voltage panel, main switchboard, sub-switchboard, protective relay, transformer, genset and distribution board, with ratings, serial numbers, photos and single-line drawings, in asset management features.
Relays and breakers sitting under their switchboard, so each has its own test history.
Printable QR stickers for each panel, and a log of every edit with the user and time.

Competent-person visits and PPM

Site planned preventive maintenance (PPM) plans that raise the monthly, twice-monthly or weekly inspection visits on their own, by voltage and switchgear rating.
Asset PPM plans for each switchboard, transformer and genset, by date, by running hours or whichever comes first, in preventive maintenance.
Separate checklists and technicians for the monthly visit and the yearly service in one cycle.
Missed visits flagged and rescheduled after a set overdue period, and newly installed panels joining the right plan by their criteria.

Long test cycles and certificates

Certifications on custom frequencies, such as the five-yearly installation test, the two-yearly relay calibration and the installation's registration renewal.
Due, overdue and done status, with reminders by email, in the app or both, and the test certificate filed with each record, through compliance documentation.
A dashboard of what is overdue, what falls due this week and what was finished last week, by zone or equipment type.
A dashboard of overdue tests, those due in the next 7 days and those completed in the last 7 days, filtered by equipment type, group or service zone.

Readings, defects and repair jobs

Number fields for insulation resistance, earth resistance, load current and relay trip times, keyed in on site as exact values.
Thermal images, test sheets and photos attached to the job, with watermarks on camera shots.
A failed answer opening the repair job and its tasks at once, and a recheck if you want one.
Ordered steps on each job, such as isolate, test and energise, with steps that must be done before the job can close.

The right chargeman on each job

Jobs given out by skill, availability, shift, leave, zone and live location, so a PJ8 job only reaches someone who holds that category.
A drag-and-drop scheduler with a backlog for unassigned work, in scheduling and dispatch.
A message to the technician whenever a job is given to them or moved.

Chargemen in the field, with van stock

The FieldEx mobile app in English, Bahasa Malaysia and Chinese, with the panel's past jobs, its checklist, its readings and the parts in the technician's van stock.
A sticker scan that opens the panel and its checklist, then photos and the owner's signature on the phone.
Jobs and tasks can be downloaded and worked offline, with check-in, check-out and travel synced later.
Spare parts used on the job recorded from the technician's own stock, with reorder alerts per stock location, in spare parts inventory.

Inspection reports and job sheets

A job sheet PDF for each visit with the equipment, findings, work done, parts and prices, time in and time out, photos and the owner's sign-off, emailed with a log of when it went out.
Maintenance contracts with start and end dates, linked to the installations and PPM plans they cover.
Owners seeing their equipment, last-serviced dates and coming PPM in a branded customer portal.
Reports by installation, client or defect, downloaded or emailed on a timetable, in reporting and analytics.

How many chargeman or supervisor visits does each installation need a month?

Regulation 67(2) of the Electricity Regulations 1994 sets the minimum by voltage. An installation up to 600 V that takes electricity through switchgear rated 100 A or more needs at least one inspection visit a month by its competent person. Above 600 V and up to 11 kV, it is at least two visits a month, and from 11 kV up to 132 kV at least four. The guideline from Jabatan Kerja Raya (JKR) on registering and operating electrical installations (CKE.GP.05.02.(00).2014) carries the same frequencies in its Jadual B.

For a contractor providing competent persons to many clients, that is a monthly roster where every installation has its own count.

What FieldEx does about it

Visit counts per installation: each installation's site plan is set to one, two or four visits a month to match its voltage.
Competent persons by category: visit jobs need the matching skill, so a high-voltage installation's visit only goes to a chargeman or engineer qualified for it.
A monthly view of every client: the dashboard calendar shows each installation's visits for the month, done and outstanding.
Proof of each visit: check-in and check-out times, the checklist and photos are kept on every visit.

What must the competent person report after each inspection visit, and by when?

Regulation 68 of the Electricity Regulations 1994 sets three duties. Under regulation 68(1), every inspection's findings, recommendations and instructions are recorded and directed to the Commission and the owner. Under 68(2), the engineer or supervisor gives the owner, management or licensee an inspection report within 2 weeks of the inspection. Under 68(4), an Inspection Certificate in Form I goes to the Commission within 2 weeks as well. Regulation 68(3) requires the owner to keep a book of all these records and reports, open for the Commission to inspect at any time.

What FieldEx does about it

A two-week clock on every report: a service-level agreement stage can time each visit from completion to report sent, with alerts before the 14 days run out.
Findings recorded on site: the visit checklist captures findings, recommendations and instructions against the installation.
The report sent and logged: the inspection report PDF is emailed to the owner with a log of when it was sent.
The owner's book, digitally: every report stays on the installation's record, and the owner can download them from the customer portal.

How often must a non-domestic installation be tested under the Electricity Regulations?

At least once every 5 years. Regulation 110(3) of the Electricity Regulations 1994 says an installation other than a domestic one must be checked and tested by a competent person at least once in every 5 years, or whenever the Commission directs. JKR's guideline, section 7.8, turns this into a process for government buildings: check the test validity date, then appoint an Electrical Services Contractor (Kontraktor Perkhidmatan Elektrik, KPE) to carry out the test.

A survey is only as useful as its follow-up: every hot spot needs a record of the reading, the location and the repair.

What FieldEx does about it

The five-year date on each installation: the periodic test is a five-yearly certification with its due date, reminders and the test certificate attached.
Earlier tests when directed: if the Commission directs a test, the certification is updated for that installation only.
Quotes from the due list: reports list installations reaching their five-year date by client and month, so your team can propose the test ahead of time.
Hot spots become jobs: a fail on the survey checklist raises the remedial job, with a retest booked after the repair.

How often must protective relays be tested and calibrated in Malaysia?

At least once every 2 years. Regulation 110(4) of the Electricity Regulations 1994 says every protective relay and device of an installation must be checked, tested and calibrated by a competent person at least once in every 2 years, or whenever the Commission directs. JKR's guideline (section 7.9) makes checking the relay setting validity date part of its process, and JKR's electrical inspectorate manual quotes the same two-year rule.

On a site with dozens of breakers, the critical ones need to be marked, so the 3-to-5-year cycle isn't spread across equipment that doesn't need it.

What FieldEx does about it

Each relay on its own two-year cycle: relays are components under their switchboard, each carrying a two-yearly calibration certification.
Settings and trip times recorded: test results and trip times are entered as number fields, and the relay test sheet is attached.
Reminders before the date: they go out ahead of each relay's due date, by email, in the app or both.
Relay history kept: every test, setting change and replacement stays on the relay's record.

Who is responsible for keeping a building's electrical installation in good order?

The owner, management, licensee or occupier. Regulation 110(1) and (2) of the Electricity Regulations 1994 require the installation to be kept in good working order and place that responsibility on the owner, management, licensee or occupier, or their servant or agent. Suruhanjaya Tenaga's ECOS guideline on installation registration adds that the owner or building management must register the installations they own or operate, under section 21 of the Electricity Supply Act 1990.

When a contractor is that agent, the owner relies on your records to show the duty was met.

What FieldEx does about it

The owner's duty, documented: each installation's plans, visits, tests and repairs are kept on its record for the owner to see.
The owner's view: through the customer portal, the owner sees equipment, last-serviced dates and coming PPM, and downloads job sheets.
Repairs owned and closed: each defect is a job with an owner and a status until it is fixed.

Who is allowed to carry out electrical maintenance, testing and calibration in Malaysia?

Only a registered contractor. Regulation 71(1) of the Electricity Regulations 1994 says no person may carry out maintenance and repair, overhaul and service, calibration, testing and commissioning of any installation or equipment, or locate cable faults, without a valid Certificate of Registration as an Electrical Services Contractor. Suruhanjaya Tenaga's ECOS contractor registration page lists Electrical Services Contractors under regulation 71 and Electrical Contractors under regulation 75, and its guideline puts work above RM1 million in Class A.

What FieldEx does about it

Your registration tracked: your company's registration certificate can be kept as a certification with its expiry and reminders.
Work types matched to people: testing, calibration and cable fault jobs can each require their matching skill.
Who did what, on record: every job names the technician, the time on site and the result.
Test instruments tracked too: your own testers and meters can be assets with their calibration due dates as certifications, and the certificate attached.

What do the chargeman categories such as A4 and B4 cover?

Suruhanjaya Tenaga lists chargeman (penjaga jentera) categories by voltage. For low-voltage systems they include A0 (PJ1), A1 (PJ2), A4-2, A4-1 and A4 (PJ4). For systems above low voltage, at 11 or 33 kV, they include B1 (PJ7) and B4 (PJ8). Regulation 60 of the Electricity Regulations 1994 says the competent person who works, operates or controls an installation is recommended by an Electrical Services Engineer, a Competent Electrical Engineer or, for installations up to 600 V, an Electrical Supervisor.

What FieldEx does about it

Categories as skills: each chargeman's category can be set as a skill, such as A4 or B4, on their profile. Each skill can carry an expiry date.
Jobs matched to the category: a substation visit at 11 kV can require B4, so only B4 holders are offered it.
A fallback when nobody fits: if no qualified chargeman is free, the job goes to the next group, alerts a supervisor or waits unassigned, as you set.
More tests when defects show: a failed sample answer can create a follow-up inspection for the wider check.

How long is an installation's Suruhanjaya Tenaga registration valid?

Between one and 5 years. Regulation 3(3) of the Electricity Regulations 1994 says a Certificate of Registration for an installation is valid for not less than one year and not more than 5 years from the date of issue. Suruhanjaya Tenaga's ECOS guideline says registration is the owner's duty under section 21 of the Electricity Supply Act 1990, and failing to register is an offence. JKR's guideline notes that the certificate must be renewed every 5 years using form ST KE(9).

What FieldEx does about it

Registration expiry on each installation: the certificate of registration is a certification on the site, with its expiry date and reminders.
Renewal as a job: the renewal can run as a job with tasks for each document and inspection needed.
The certificate on file: the issued certificate is attached to the record and can be downloaded at any time.
Codes reported: reports group findings by code, client and site, so open dangerous items are never hidden in a PDF.

What are Borang G and Borang H, and who signs them?

Suruhanjaya Tenaga's ECOS installation registration guideline describes Borang G as the Supervision and Completion Certificate (Perakuan Penyeliaan dan Penyiapan), filled in by the single-phase or three-phase wireman who did and supervised the wiring. Under the Electricity Regulations 1994, Form G (Certificate of Supervision and Completion) and Form H (Certificate of Test) are required by regulations 12 and 13 and prescribed under regulation 14. After wiring or rewiring, the installation is tested by an authorised single-phase or three-phase wireman, who certifies Borang H.

What FieldEx does about it

Wiring jobs with their forms: each wiring or rewiring job can have the signed Borang G and Borang H attached on completion.
The wireman named: the job records which wireman did the work and tested it.
Tests required before close: the testing task can be required before the job can be closed.

What must happen when the competent person finds a dangerous defect?

Regulation 70 of the Electricity Regulations 1994 says that when the engineer or supervisor finds a dangerous defect, they must immediately tell the owner, management or licensee to make good or remove it, and report immediately to the Commission. Regulation 68(1) adds that every finding, recommendation and instruction is recorded and directed to both the Commission and the owner.

Those are user checks, but on a maintained site they are often bundled into the contractor's six-monthly visit.

What FieldEx does about it

A dangerous answer raises the alarm: a "dangerous defect" answer on the checklist creates the repair job and notifies the owner and your engineer at once.
Evidence on the defect: photos and readings are attached to the job, with the time the defect was found.
Closed and proven: the repair job's completion records when the defect was made good, with the owner's sign-off.

Which electrical accidents must be reported to Suruhanjaya Tenaga?

Section 33 of the Electricity Supply Act 1990 requires any accident or fire involving an installation or electrical plant or equipment that causes loss of life, hurt to any person or serious damage to property to be reported to the Commission. Suruhanjaya Tenaga's FAQ explains that the report is made by the quickest means available, followed with the least possible delay by a written report.

What FieldEx does about it

Incidents logged as jobs: an accident or fire becomes a job on the installation, time-stamped from the moment it is reported.
Steps that can't be skipped: the incident job can hold ordered tasks, such as make safe, notify the Commission and file the written report.
Everything attached: photos, readings and the written report stay on the job and the installation.

Which wiring standard applies to electrical installations in Malaysian buildings?

MS IEC 60364. Suruhanjaya Tenaga's 2021 presentation on electrical installation standards in Peninsular Malaysia and Sabah lists the Electricity Supply Act 1990, the Electricity Regulations 1994, MS IEC 60364 "Electrical Installations of Building" and MS 1979, its code of practice, as the basis for wiring design. Seminar material from Suruhanjaya Tenaga and the Institution of Engineers, Malaysia (IEM) on MS IEC 60364 names Part 7-710 for hospitals among the special locations.

These are engineering studies, not maintenance visits, but they sit on the same equipment and change the labels on it.

What FieldEx does about it

Checklists built to the standard: inspection checklists can follow the clauses you test to, with sections and reference photos.
Faster setup: checklist questions can be drafted with AI from a PDF or PNG of your existing checklist or procedure.
Special locations kept separate: hospital and other special installations can have their own asset type, checklist and cycle.
