sifus,

would like to share my experience changing fr 1 phase to 3 phase. i had no idea the financial impact until i went thru the ordeal....All below are TNB cost alone.

Just renovated my semiD house. Since I have 13 AC plus some other equipments, I decided to change to 3 phase.
1. TNB Meter location was at next to one of the gate pillar. Since I expand the gate, I need to relocate the meter (and change 1 phase to 3phase meter). The cost to relocate the meter is a whopping RM8.5K - just to terminate the old 1 phase and relocate.
2. Cost to pull new 100A cable (3 phase) from TNB substation (50m away) to the new meter is another RM8.9K. This one is really bothersome as TNB needs to apply permit from local council to dig the road etc.

Work scope 1 and 2 involved two different departments from TNB.

I am still waiting for TNB to lay the new cable and currently my house is powered using the old 1 phase still. Note I am not using all the ACs, the most is 5 AC at a time.

My question: is item 1 is really reasonable/necessary - I cannot believe 8.5K just to terminate the 1 phase cable and relocate. Any feedback appreciated.

Hi Ozak - Yes I have finished renovated. I Have paid item 2 but not item 1 as I am still arguing with TNB on the termination method.
Hi Weikee - I paid directly to TNB and they appoint their contractor. Item 2 I can understand since it will involved new cable plus labor but item 1 I think not reasonable. They will pull the new cable from substation (not power pole) which is about 50ft (not m as per my earlier posting) from my house.

It happen to my beside neighbour too. 1 night of nowhere, the wire joint connecting box catch fire and burn out. Just beside the house front door. Lucky a small burn out. This joint is extend by TNB when neigbour do renovation.

It is the connecting oxidise/loose. It will get hot and eventually melt and burn.

Normally a high voltage cable joint need to seal it properly with somekind of potting material.

It is the beginning wire come from the pole.

The measurement have to conduct at night to get the max result. Which is the highest load.

the bigger fuse can take it. but can ur existing cable take it continuously? even if u change to bigger cable, u still cant change the incoming, as it is TNB's property.

Added on December 19, 2012, 12:21 pm3 phase is not needed, if:

a) ur load can be handled by single phase
b) u need 400V supply

ok fixed. thnx n sorry for that.

last time was 415V, now its drop to 400V. simple as that.

I heard that it will be cheaper for you to upgrade to 3 phase if neighbour got 3 phase already as less work for TNB.

if hse haf 1 freezer n 1 fridge ok rite if 1 phase...
adi planned to do extension coz ori hhse design waste alot of land area =(

May i know what is the meaning of "Installation charges as low as RM10.00 for public street  lighting sponsored by individual"

Apply for street light for only rm10??

Do you know roughly how much bill per month for street light if turn on from 6.30 pm to 7.00 am the next morning?

from tnb website:

"For customers who wish to apply for street lighting under their own name, a connection charge will be imposed.  A monthly charge of RM10.00 will also be included in the customer’s account. Customer may go to the nearest Pusat Khidmat Pelanggan for more information on the connection charges."

So we don't need to pay electric usage? just pay rm10 every month?

Hi Sifu, thanks but I am noob in this, do you mean connecting the black copper wire with the green one ? There is 2 black wires there, one is fine wire and another one is copper type.

Serious ? Cannot learn how to DIY now and must get help from electrician ?

hi, like in my case [attachmentid=3715523] the new house comes with single phase, how do i know if can change to 3 phase or not? Just walk in to nearest TNB office? Tq

Noted. Thanks. I am going for 3Phase then. Easier and feel Safer on the overloading. 
Banting Area, Still having 3Phase Promotion? will go over and apply by year end.

Hi guys, i have bought an old house and think of changing the single phase to 3 phase. I wonder do i need to re-wiring my whole house cables or basically changing the fuse box outside my house will do?

1) Upgrade of the fuse from single to three phase, you will have to be through tnb or ask electric contractor to help.
2) you have to change the distribution board mcb to 3 phase incoming and the bus bar to 3 phase.
3) no, you do not need to require the while house.

Forgot, to say elcb have to be three phase for incoming. Specifications must comply to local authority.

I answered based in his question. It's is dependent to his load usage. U can have 30 mcb, but u can still run it on single phase, dependent to load, e.g all lights.
