Did the developer provide you with 3 TNB cut-off fuses (come with with black plastic holder)?
The fuses need to be installed/plugged into the outdoor TNB cabinet (next to electricity meter) in order to get the power supply. Also, please check the main switch (probably located in storeroom near the staircase) to make sure it is switched on.

Please do not let the fuses unattended because it probably will be unplugged by other contractors and gone. It happened to some of us before.
If possible, secure your TNB cabinet with a stainless steel lock. Similar product can be purchased at MYDIY Hardware shop in Puchong Permai.

The Certificate of Completion and Compliance (“CCC”) system which came into force in all states within Peninsular Malaysia on 12 April 2007 effectively replaces the Certificate of Fitness for Occupation (“CFO”) previously issued by the local authorities under the Street, Drainage and Building Act 1974 (“SDBA”).

CCC is issued by Architect. Developer should have attached the photocopy of it together in the file when you took the keys. The electric power supply must be available when VP. In the S&P agreement, it states that the electricity and water supply must be in place in order to let the owner to VP the new house. Developer has the accountability to make sure the electric power supply is available, else they are not duly completing their duty to let you to VP your new house. You can tell them that you will count the date and them must pay you for LD because of the absent of power supply.

If the issue still persisted, then you may consider to email their headquarter in Sri Hartamas.

Thank you Alan,
Noted.

Tomolo will be after 1 week, after tomolo still dont have power supply. I will info the HQ Sri hartamas.

Sounds like nobody wants to involve in this issue.
I am curious to know why TNB does not want to switch on the power supply.
I was told that my phase also had issue with TNB but they managed to settle before VP.
Hope this problem can be resolved soon.

Ya, wait for luck

TNB answer :
Based on the account number, the latest bill issued on 04.03.2017 with the estimated bill because there are no fuse beside the meter. The amount need to pay is RM 313.85.
