Good idea. Haha
You make me scare la. 
Then i should forget it. 
Seems like you are hardcore fella in this. 

last time use...but its not as difficult as it sound lar just probe only...red to wire, black to green...basically like that lar..and don't touch any exposed wire

Hi, wanted to know how the cables were pulled from your meter fuse to the switch box inside your house. Usually for a double story house, the switch box is located in a small store room under a staircase. My understanding is that two additional cables will need to be pulled from the meter fuse (usually outside the house) to your switch box (I may be wrong...), going through the car porch, living hall, till the store room. If this is the case, will it be a big messy hacking need to be done?

Appreciate if you could also PM the contact of your contractor, thank you!

hi all, anyone can recommend me a tnb runner/contractor ?
i want to upgrade from single phase to 3phase..
please PM me thanks

Hi Supersound

after renovation actually..
my previous contractor went missing, he suppose to have this done, but you know...
i am still on single phase.

i have 4 airconds
-2.0hp, 1.5hp, 2x 1.0hp

and 3 water heaters
even though the chances to have all water heaters to run concurrently is very low, but i still dont dare.

the internal wiring is done, but all MCB's are running via a 63A ELCB.
I need to upgrade this to 3phase configuration

hi guys, my new house already come with TNB cable for 3 phase but the TNB meter is running only single phase. I had change all my db and 3 phase cabling to the TNB meter. Now left only applying from TNB for the 3 phase meter which is bigger. I was told to get runner which cost around RM2.5k include deposit and replacement of the new bigger TNB meter, is this pricing ok?

Hi, bro all,
Wiring using AC 25mm amour cable for TNB outdoor meter to indoor D/B board and TNB application 60 A 3 phase direct - $ 4600

TNB cable- $ 1250

Wiring cable using 4 x 16mm + 10mm E pve cable for ground floor D/B to first floor $ 1300 (10 feet high)

Supply and install 60 A 3 phase 8 ways D/B board ground floor $ 2200

Supply and install 60 A 3 phase 6 ways D/B board first floor $ 2000

My unit is a terrace house about 9-10feet high ground floor to first floor; there are air cond 2hp x 2 / 1hp x2
For 3 room and family hall…normal only will on to 2 units (at night sleep) + freezer on usage at the same time.

Hope to get helps from someone professional guidance that any necessary to install on those cable?

I’m staying at Penang,is that costing quote is acceptable or too much over ? Total cost RM 11350..? Tq

Just learn some basic power usage calculation how much a single phase max can load. You will know how to control your house electrical appliance if you know the number.

Single phase can max load 63Ax240V = 15Kw. But that is fuse trip point. So you need to reduce to maybe 80% usage. 15Kw x 80% =12KW max load.

Everytime you buy a electrical appliance, it got state the power consumption in Watt(W) or kilowatt(Kw). If it state in ampere (A), than multiply it with 240V (2Ax240V=480w) Take all the number and total up. It cannot exceed your max house load of 12Kw. Example,

7 aircon 1HP (750w) x7 = 5.25Kw
2 Fridge  maybe 300w x2 = 600w
1 heater maybe 4kw  = 4Kw
3 TV maybe 100w = 300w.

Total = 5.25Kw + 0.6Kw + 4Kw + 0.3Kw = 10.15Kw. So you only left for 2Kw for others like light, WM, pc etc... But you know that you don't use all the electrical appliance at the same time.

If 2Kw not enough for others, than apply for 3phase.

Today I just contacted the wiring man, I kena ejek by him. Cuz he was persuading me to use 3 phase due to I have 4 Aircond. He told me I have 2.5hp, 1.5hp, 2 x 1hp confirm must use 3 phase or else it will trip. So I calculate the power consumption to him and said its not even 60A how come will trip, he said it doesn't count that way, then kena ejek. So I wanna get confirmation with u guys, is he right or we(all forumers) are right?

It won't trip. if you check the outside tnb fuse sometimes it rated 100 A. more than the demand that u have right now.

total hp u have 6hp. it is not even close to 30Amp

If we used China wires should broken somewhere already, that is why we needs invest 100% copper wires at all.

Can imaging also electronic water cooker wire can be burned as well.

In sg yes

I also will want to pay that amount... hey maybe 2k per meter if its 100%, not even 99.99%

Look like you have two zone only, don't look like 3-phase. Do you separate it by 2 zone? (first floor and ground floor)?

Too blur to identify.

Usually with 3 Level together is 3-phase

Its looks to be 3 phase but need a multimeter to confirm. If you get 3 phase voltage (415V) between the 2 incomer wires confirm 3 phase wiring. If you measure 240V between the 2 incomer then its single phase.

I'll describe your DB, the top most copper terminal block is the Neutral terminal block. you have 2 Neutral terminal blocks (one at the top and one more btm denoted by the black wires) so logically means a three phase wiring.

The 1st row of circuit breakers is two single pole 63A fuse carriers with associated 2Pole ELCB next to them. Your wireman arrange them one on left and one on right. It's not the usual practice to wire up a DB. I would wire each phase wire to a separate row with double pole (L+N isolated) isolator then to ELCB and then to mcb's.

The DB looks a bit messy with wires not fully terminated. Looks like a job in progress.

I need some help on wiring issues.
My house is 3 phase ready. Am planning to redo the wiring for the whole house. Since i dont have much electrical goods at home, i am planning to have single phase wiring.
Would it still be safe or will i be facing any problem later. Interms of cost how much percent increment would it be between single phase and 3 phase?

Thank you sifus.

Thank you supersound for the advice. When i say 3 phase ready it means that the tnb meter is 3 phase ready but i think the wiring  in the house is single. Apparently i have to redo due to faulty and horrible wiring job done during renovation.

The question now, i got some feedback from electrician that i have to have 3 phase wiring still otherwise it wont be safe. Is that true? Of course it comes back to costing, my impression 3 phase would be way much expensive compared to single. Any advice? Thank you sir.

Hi,

I receive TNB letter for electricity supply application by my developer, the letter mentioned is 1 phase wiring. Can I request 3 phase wiring with my developer?

Or I can only do any changes after VP?

My house currently 1 phase, but wiremen said its 3 phase ready since after looking at my meter box only use fuse at blue, while red and yellow no fuse. He said if want to upgrade to 3 phase just need to pull cable from meter box to the DB and change new DB. Is this correct? Costs around 5k. The purpose i want to upgrade to 3 phase because want to add more air cond. currently got 3 aircond (2.0 at living, 1.5 at master bedroom and 1.0hp at guest room). Is it possible to have plug point at 1st floor living, ground living and guest room on same phase? Need to use homeplug for unifi
