your online submission (free and direct with tnb) is different from runner submission AKA TNB certified contractor.

So if i submit directly with tnb, they will also appoint their contractor to come and inspect first right?

Edit: The Account number and IC must be owners one?

yes but TNB will only come after your tnb certified electriciant does the submission.

yes.

guys need your opinion. I'm trying to convert my current 1 phase electricity to 3 phase and currently my contractor is doing renovation at my house.

The questions are:

1. Do i need to change the whole wiring in my house if i were to convert to 3 phase from 1 phase?

2. I was quoted RM4.5k for application, contribute to tnb and labour work by my contractor. is it reasonable?

What is labour work ? Need to give more details.

pulling cables from the reader box, meter box, converting to 3 phase wires as what normally contractors have to do to upgrade to 3 phase.

Sounds very reasonable.

No idea how you can say that without any breakdown description of type of labour, quality of workmanship, quantity of material, installation details, etc

Better talk about the weather and rain .. same context..

Can u guide me what should I ask the contractor to list out and what should i expect them to do to convert from 1 phase to 3?

Either yourself or contractor must have a dimension layout plan of your structure and external line of the 3ph electricity source.

1. The electrical contractor must then indicate on that layout plan the route of the existing 1ph and new 3ph wiring from source to your electrical db.

2. All electrical lighting pts, sockets and main electrical appliances must be indicated on the layout plan.

3. The existing and new wiring path shown on the layout plan.
Highlight new wiring line indicating cable size, ug/high level run from db to pt.

4. Do a quotation base on this drawing for the bill of materials, supply/install/transport/storage applicable labour and authority submission/follow-up/approval. Make good any damages during works or to client's acceptance.

5. Testing and commissioning.

6. Agreement to the quotation based on bill of qty i.e contractor owner payment schedule and period of completion

Use this guide line so the contractor can inform you and no arguments on scope of works.

Thank you for your detailed explanation. Really appreciate it.
If all those u’ve listed including submission & TNB fee is done by my contractor, is rm4.5k a reasonable amount to be payed?

First me see the material list and labour qty breakdown

Your question has no details except a general description and a lump sump figure

Just sharing a 3-phase upgrade guide for everyone’s benefit since there isn’t clear instructions on what is the process and how to go about it. So I hope this will be useful for future readers.
____________________

Step 1:
Do your necessary preparation works such as (i) preparation of meter box compartment at required location; (ii) converting your distribution box to 3-phase ready; (iii) doing the required armoured cable laying from meter box to distribution box;

Tip: Hire a qualified/certified electrician to do all this. Basically, you want to be “3-phase ready”.

Step 2:
Ask your electrician to prepare the meter board and 3 phase cables wiring as per pic below. Note that this is a sample but it should look something like this depending on your requirement.
By this stage you are to called 3-phase ready.

Tip: Ask your electrician to ensure its as per TNB’s required specs. You will be able to find the spec pdf on TNB’s website.

Step 3:
Go to myTNB’s website, register and then apply to upgrade your power to 3-phase.

Step 4:
Select a TNB licensed company from the list as your contractor and to do your submission to TNB (i.e runner). At this point, you only need a runner to do the submission to TNB for you. You have no choice but to select a company from the list as your runner.

Note: they can also do all electrical works to be 3-phase ready but its your decision to hire your own contractor or use one of the panel contractors.

Tip: call up each company you have shortlisted to ask them how much are their submission fees are. You would want to let them know that you are 3-phase ready and only need to do the submission process to TNB. Runners generally charge a fee of RM600 to RM1.5k depending on which company you engage. Typically, they will charge a high fee of RM1.5k.

Step 5:
The runner will then contact you to come over to your house to take pictures of the meter compartment, wiring board and nearest pole to pull the cable for 3-phase power. This is to ensure everything is in order as per TNB’s specs before submission.

Step 6:
Once the runner has made the submission to TNB, it will take around 3 weeks for them to assess how best to pull in the cable to your house. The runner will inform you if they are putting a new pole up or digging the road.
Note: digging of road will require special permit from the local council and it might include additional cost to be estimated by TNB.

Step 7:
After the assessment period, TNB will send you a invoice to be settled prior to starting of construction works (i.e pulling the cable and installing the meter).

Typically, fees are:
1. Contribution fee – RM1,700
2. Deposit top for 3-phase – RM200

Note: Generally, the cost should be within the above figures unless special case where it includes road cutting where TNB does not want to bare or your area is really secluded.

Step 8:
At this stage, TNB should have completed the erection of the pole and installation of the meter. Further appointment will be made to install the fuse and remove your old single phase meter etc.

Step 9:
Congratulations! You now have 3-phase power. The power connection process is very simple. TNB will put in 3 fuses to complete the connection.

Note: TNB is NOT responsible for anything that is inside your house compound so if there are any power or wiring issues then it’s up to you to rectify it hence a good electrician is important. TNB’s scope of works is only limited to up to the meter compartment box.

Thanks, really very helpful information.

Thank you, I'm glad I found this. Do you happen to have any reputable contractor that does this in Selangor area?
Subang Jaya in particular?

Can i have your contractor contact?

Contractor for what first ?

1. Wiring works
2. Runner (submission)

Hi Peppa,

Its for wiring works.
Also shouldn't the wire man? have runner or contacts to help on this?

Sorry if this doesn't make sense, considering changing my house I'm currently staying from single phase to 3 phase.

The wiring man will usually have contacts of runners.

Great, good to know! thank you so much!
