sure you can. you can do whatever you want to do right after the tnb meter.

what you cannot do is with modification within meter or before meter.

see those two wires out of your meter? (main and neutral) yes, that is your territory.

sure why not.

i dont face such setup before but it can be done actually.

normally if you have big complex (shopping complex for example), have lots of tenants and you are taking bulk supply from tnb then go ahead and do it. but for residential i dont think that is really necessary..

whats the problem you are facing actually? overcharging in electrical bill?

i am not so sure, about cost. but it is more practical for a larger premis.

but for only three room and each have its own meter? well, you are the landlord, its your call.

Not as easy as it seems. You need to determine the individual power lines to each room i.e. for the 13A sockets and lights. Some developments the developer uses a shared system i.e. one MCB to a few power points, perhaps from one room to another to save cost. Not so ethical (due to lax checking) but still workable as long as not too much looping. But from your DB box size, I suspect a few points are looped.

And of course it is not cheap to install the meters (not credited digital ones easily cost above rm200/unit). Somemore you need to do internal wirings and stuff like that.

Suggest you kill the idea and talk nicely to your tenants to save electricity and the Earth 

you can install a meter by capture measurement of the dedicated MCB. no wall hacking require, jz wiring job with enclosure will do

blasto, report back your progress. am also interested how/what are the meters look like. thanks thanks

How are your going to calculate? If Room A uses 100 kWh and Room B uses 175 kWH, you will be billed the following.

For the first 200 kWh (1 - 200 kWh) per month  sen/kWh  21.8 = RM43.60
For the next 75 kWh (201 - 300 kWh) per month  sen/kWh  33.4 = RM25.05
Total bill RM68.55. Now who pays what? Both also use under 200 kWh. If you average the total bill RM68.55/275 kWh = RM0.249.
Will Room A ask why should he pay RM0.249 when he should only pay RM0.218 ?


It looks like you are renting rooms and that is your purpose, right? No one wants to do what you do otherwise. Then imagine if Room A 100 kWh, Room 2, 175 kWh and Room 3 215 kWh. Will Room A & B ask Room 3 to pay RM 0.334 since he exceeds the 201 kWh?

Charging only the electricity used by a particular room - that will be undercharging the tenant.

There will be electricity used in the common area - the lights in the living hall, the kettle in the kitchen, the fridge and so on.

If you install sub-meter, how to do it so that it can be fair ?

wow!! what is the cost like? i wanan do also

If you installed submeter to each room, maybe the bill calculation can be like this :-

1. Each tenant has to pay the amount charge according to the submeter for the room + average common area charge.

2. How to calculate common area charge :-

        common area charge = Total bill - room1 - room 2 - room 3

    Average it for 3 rooms = common area charge / 3

Do you think the tenants will find it fair to calculate this way ?
