Kota Kinabalu: The Energy Commission of Sabah (ECoS) acknowledged concerns raised by owners of standby generators (gensets) at residential premises regarding the requirement for periodic inspections by Competent Persons under the Electricity Supply Enactment 2024.
Its Chief Executive Officer Datuk Abdul Nasser Abdul Wahid clarified that the requirement does not apply to everyone in the same way.
He explained that installations using low-voltage systems and switch-gear rated below 100 amperes, whether in homes, shops, or factories, do not need regular inspections by a Competent Person.

As for industrial premises, including petrol stations, the inspection schedule has been relaxed, from once a month to once every three months.
Abdul Nasser said for large-scale commercial and industrial premises receiving supply at 11,000 volts, the frequency of visits may be reduced from twice a month to once a month.
For installations receiving supply from above 11,000 volts up to 132,000 volts, the frequency may be reduced from four times a month to twice a month,” he said.
“These adjustments reflect the level of risk involved — the higher the voltage, the greater the potential danger not just to owners and workers, but also to the public,” said Abdul Nasser.
He said these changes are allowed under Regulation 72 of the Electricity Supply Regulations 2024, but stressed that owners must apply for reduced inspections. Each application will be assessed by ECoS officers to ensure safety standards are still met.
Despite the relaxation of rules, Nasser reminded all genset owners that they remain fully responsible for the safety of their installations.
