If consistan using 14,400 or maybe at 90% 13,000 watt than is good to change to 3 phase, but only just short spike don't need.

BTW, if using 14,400 watt, that is paying RM 5+ per hours, if use for 3 hours perday that is paying RM 450.00 for just this 3 hours x 30 days. Add with other daily usage, minimal house hold electrical bills will go up to RM 500++

I see.

That sounds a lot to me. But very likely some other users really paying at this quantum.

Monthly bill rate is not a good way for 3 phase decision. Need to know the house peak load.

If one stay in bungalow, sure the normal peak load will sometime exceed 14.4kw

For my humble double story house, during party, i switch on most of the lights, and 3 units of a/c without switching on the water heater. Still fine, that nigh itself only use about 8kwh for 2.5 hours.

Most important, as house owner, know how much your utilities bill and where and why the amount coming from. Be wise.

ELCB wont trip during an overload la

ELCB is Earth Leakage Circuit Breaker

So u know it wont protect against overcurrent, right? Good

Yes, and earlier is my typo error, is the main CB (c63) in the DB box that did not trip.

haha okok

Actually if i run 40amp on my first floor, and 40 amps at my ground floor. It won't trip. Because I run two separate DB box, with independent ELCB and main MCB. Only the incoming fused will blow.

Technically, i can just pull one more phase for my first floor. Too bad, TNB don't offer 2 phase circuit

Not because youre STAFF and want to agree with you - but - you are right. Ive 3 phase wiring when I purchased my house and my bill with 2 air cond (10 hours each a day) and nothing other significantly large power consuming equipment at home - my TNB bill has been constantly on the average RM450 per month - now for 4 years and going.

So whoever thinks that 3 phase wiring means save TNB bill - hello wakey wakey

Thanks for the tip. Just wanted to know. I guess I'm still ok on single phase

2 a/c only and not even on 24/7? why is your consumption so high? you must have serious room for reducing your power consumption.

Yeah, i feel it is kind of high as well.

Gemelite Interior Studio,

how is this advertisement related to 3-phase wiring? Use the services notice board and remove this post OK?

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.

i think dun need to change to 3 phase

Have you finish renovate and enjoying staying? Or still doing the renovation?

If you already staying and running 1phase, than continue using it and monitor any fuse blow that cause by overcurrent. (overuse) If it didn't happen, than save your money.

But if you pay everything already, than no choice but continue your 3phase.

You pay directly to TNB or agent? Sound expensive to me. My neighbor change to 3 phase, but remain the meter on the wall, she told me is cheaper alternative but it sure look one kind with 4 cables loop in. Did not ask her the actual conversion cost her, but she told me was not too bad, less than 5k.

Maybe your due to the covnersion and moving meter to the gate. Is the power pole right outside your house or accross the road? SemiD may need 3 phase since you have 13 AC

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.

Item 1 really look expensive. Dealing with TNB is never cheap, I relocate my meter, ask TNB relocate the wires already cost me RM 1.2k. Maybe you ask them for breakdown detail.
