I am buying a condo over 20 years of age. Do you suggest replacing the wiring of the whole unit? How much is the estimate price range for around 1200 sqf area with 2 bedrooms? Thanks guys.

Based on what I understand, the charging is based on the points, be it light or power socket. E.g. one light point is between RM 90 - RM140 (recent quotation I received). For 13A socket, RM 120 per point. 15A socket (for owen, washing machine, fridge), it is about RM 230 per point.

Have you checked the condition of the wiring?

I recently rebuild a new house. The wireman proposed 1.5m2 wire for the light. Out of curiosity, I checked my existing condo (which is 30 years old). The wire is much biger diameter. So, I think old propoerties used better quality materials. Of course, that also depends who was the developer.

yeah same for my old house, now i am hesitating to replace all my old wires as they have better quality.

It depends on whether the wiring is properly installed or hack jobs from kitcab people.
The latter, u better replace, they anyhow install cheap wires.

So since ur doing refresh works
I would suggest refresh the DB box and bringing it up to code, that is, in terms of RCDs and MCBs.
Brand wise.. only trust ABB or Hager in Msia for the best. Hager cost more but equally good as ABB; usually spec ABB.
Like 30mA mains (whole house) and individual 10mA RCDs (PER water heater).

MCBs very cheap like RM7/8 each for ABB.


U need to check what cable size used for the 15A socket.
If 2.5mm then there's no difference from 13A socket wiring.

Last time copper not that expensive, they don't cheat.
Be aware if you're not using best name brand cables (MCMA cartel like Mega Kabel/Fajar) or better ones like Caramay - everything else that's not in that price bracket are all substandard cables.

Get a wireman to inspect the insulation and bring up the DB box to code also.

Thanks for your advice.

Indeed a lot of electricians are cheating nowsaday. I fired the electrician that was in charge of my new house 3 weeks ago. For CCTV cables, he quoted me branded Cat6. But, his subcontractor (a group of Myanmar workers) used unbranded Cat5e. His argument was CCTV do not need Cat6, but the contract signed was Cat6! After getting a few electricians to view the light points, found out the Myanmar workers did not pull the earth wire. When my main con confronted this Chinese electrician, the answer is LED lights don't need earth.

So, better be careful and select a reliable electrician. Specify clearly that no further subcontracting is allowed.

can i use the light point wire to connect to a power socket and use the socket for cctv ?

your light point and socket point quotation is rather expensive :0

I agreed. Do you have anyone to refer? I just fired the electrician and want to find new one.

Paying top dollar should give good stuffs, but it seems that even paying top dollar also doesn't guarantee top notch services.

Mine is based in JB. Was quoted RM55/light point, Rm95/socket. Just for your reference.

anyone got good electrician for area around KL?

Wao, that is very good price. Do you know what type of cables they use? Mine is mega and concealed with PVC conduits. But, I do agree they are very expensive. Worse, the Chinese electrician further subcontracted to a group of Myanmar workers without any local to supervise. That is the reason I terminated their services.

1.5mm for lights.
2.5mm for power sockets.
4mm for water heater, air-conditioning or oven. Some water heaters must be connected straight to the MCB. No power socket, plug or switch in between.

where is your location Bro?

KL, a lot of electricians are quoting very high price.

if there is alot of point or work to do, lets say more than 20 units point, price can be reduce or nego.
Like 1 light point can be RM45 to RM55
1 power plug point of coz with looping will be RM65 to 95
If you insists everything have to pull for new wiring, than this can get very expensive

Yes, you are correct. My brother is building his house at Penang. That is the practice there too.

But, in KL, especially certain locations, the price are very expensive. Actually, I am engaging a main con to manage everything. The prices I mentioned in the thread are without his mark-up.

The lesson I learn is to avoid electricians that want to get the contracts and after that outsourced completely to foreign labour.

Bro, copper price has gone up more than 30% and you want the supply and installation price to remains the same?

Actually, my price was back in May 2021. The problem I face is the location. The moment they know the address, they have many reasons to raise the price.

Recently, I joined a facebook group (mainly for Mandarin users) and got a few electricians to quote me. The price per light point is only RM 65 - 75 per point and the 13A is only RM 100 per point for the current market price.

I am going to share the quality of the "Data Centre" electrician. He claimed that he has done several data centres. Contract signed is Cat6 wire. Get the foreign labour to lay Cat5e unbranded wire.

These are the quality of the "Data Centre" electrician, not mentioned the light, aircond and fan switches of my living room are put at car porch:

Pendant light point is placed next to the fan.


Cat5e was used despite the contract and pricing is Cat6. Argument is I don't need Cat6 for CCTV. But, price is the same.


Because I said I will use LED light, no Earth line for the points.


My requirement is concealed and this picture shows my bathroom. The network and 13A cables were put like this. Below the sinks. If he forgot to place the PVC conduit during casting of slab, he can hack. But, the electrician refused unless I paid VO price. Like this, can I do water proofing?


For a 60 sen joint that was broken - would you replace a new one or tore a piece of paper and cover the hole?
