KOTA KINABALU, Jul 3 – The Energy Commission of Sabah (ECoS) acknowledges the concerns raised by owners of standby gensets in residential premises regarding the requirement for periodic visits by Competent Persons as stipulated under the Electricity Supply Enactment 2024.
ECoS Chief Executive Officer, Datuk Ir. Abdul Nasser bin Abdul Wahid, clarified that under current regulations, not all registered standby genset installations require periodic visits by a Competent Person. Installations operating at low voltage and supplied through switchgear rated below 100 amperes, whether in residential premises, commercial, or industrial, do not require such periodic visits.
ECoS has also decided not to make periodic visits mandatory for low voltage registered installations in residential and commercial premises supplied through switchgear rated above 100 amperes but below 300 amperes. For industrial premises, including petrol stations, the frequency of visits may be reduced from once a month to once every three months.
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. This is due to the greater risks posed by any operational failures at such premises, not only to the owners but also to the workers operating the installations, occupants, and the public.
This decision is in line with the authority granted under Regulation 72 of the Electricity Supply Regulations 2024. However, any request for reduced visit frequency must be applied for and is subject to safety level verification by ECoS officers.
Nasser emphasized that although exemptions and reductions in visit frequency are permitted, owners of installations are fully responsible for ensuring the installations remain safe.
He also urged installation owners to contact ECoS offices or visit the “Talk2ECoS” portal at www.ecos.gov.my for any issues or further clarification on this matter.
