The cables infra before your unit meter belong to TNB. If the tapping is before the TNB’s meter and it serves another unit, it is not your issue.

If it taps before the TNB’s meter and goes to your unit, you will be at fault.

For Selangor’s PBT, there are no more overhead cables allowed (all buried underground), hence the tapping before the meter is quite impossible unless it was carried out during the construction.

With that magnitude of the usage, the incoming source intake could be easily a 200A ~ 300A CT meter.

200A ~ 300A CT meter, the bypass cable upfront cost is high. I doubt anyone who wants to steal utility will be willing to come out with such massive upfront cost. More likely, the tenant is using an existing meter registered under the owner’s name.

Your analogy is valid. If the tapping is from public infrastructure didn’t go into your unit, ask TNB to prove that you are at fault and benefit from the theft. If they can’t provide the proof, the argument stops there.

Your speculation statements post the edit - you need to seek your answer from the other.

Too negative speculation statement and almost will not happen.

Reasons:-

1) No developer so stupid to come out with additional capex to benefit buyers. This additional thing they cannot even bill the buyer.

2) The unit compliance is supervised by the site supervision team reporting to the Engineer and Architect. No stupid Engineer will sign the CCC clearance & risk their practising license got suspended. What benefits the buyer can offer to Engineer to make them risk their practising license being at risk? If not logic, pls throw away the idea.

The risk >>>> reward.

Only idiot Engineer will do this stupid decision.

The theft modification is more likely to happen after the project handover ( developer will be out of the picture), where the buyer instructed their electrician to modify it.

As I explained, for the cable buried underground for Selangor, it is very unlikely to happen, hence you can eliminate this possibility.

You need to view thing from the broader angle. Only Selangor PBT enforce underground distribution cabling. It doesn’t mean other states are using the same.
