This just popped into my mind this afternoon thinking about those homestay people are going to rent for holiday! Especially in places like Cameron Highland where WH is a must!

Products made in Europe (if it really is) are expensive because of manufacturing cost there. Even when there are similar product from China, they would buy Made in Europe. Nowadays due to component shortages, many Western product s are also using components from China. This is very common now. Those US companies producing their products in China is shifting to Malaysia too. Well, labor in China nowadays are comparable to Malaysia, I'd say, but other cost is higher because components are still from somewhere else.

Many Europe companies are assembling their product in Europe but but parts/modules from Malaysia too. Component from China are also used for their low cost. The CE certification is not like UL in the US. It is the manufacturer that declare and responsible to meet the CE requirement. It is not tested by lab in countries that are importing the products or at least CE certified lab.

The branded product is also expensive because the insurance they paid to protect themselves against any possible lawsuits too . Western manufacturing agreement is a stack of papers while China only need 1 piece of paper. This was true story from my American ex-boss. My work now is estimating cost to produce a product based on BOM list and drawings provided by possible customers and the selling price difference would surprised most people.

Tumpang question since same power rating 3300w.
Is the below safe?

2mm cable? Not 2.5mmsq for the in-wall concealed cable?

Its OK but you might consider using a CEE plug instead of DP switch (so u can disconnect the oven)

For a 3300w power-rated oven, 1.5 sq mm cable is questionable by a mile!

Secondly, I will not use a 2.5 sq mm wire for a power-hungry appliances like oven, I would go for 4mm as you are going to run your oven for a long duration. You are probably testing its limit - a water heater at around 1A to 2A higher usually runs at a much shorter duration is already advisable to go with 4 sq mm wire. Regardless of the wire size, you need to invest in a better quality wire so it can lasts you long - having SIRIM should be the bare minimum

find technician to do dont pandai pandai do things like this... especially shower one.... u can get fry.

My bad. Yes 2.5mm but non Sirim cable installed by contractor

Got some champion use uncertified wire before.
Those that scared to show marked cables to customer are probably suspect.
Especially those using nonstandard tomfoolery calculation 40x0.193 or 40x0.076 type cables are suspect. Because our usual ST spec is 1.5 2.5 4.0mm any funky spec of wires are deemed as suspicious already.

Cost cutting. The minimum spec should be
stiff cable (MS 2112-3) Caramay, Mega Kabel, TONN, or those MCMA cartel
or flexicord (2112-5) Fajar Cable.

Copper price more or less is like that one. Cheap stocks aren't copper.

Using non-sirim product is against the law - you can try raise a complaint to ST if you want but make sure you do your homework and have the necessary documents/information - and also if you think it is worth to go through the "process". It is completely up to you... that's why there is always a phrase of "prevention is better than cure".

Using a non Sirim cable you would expect the cable quality is at least 30% bad (just cincai plucking from the air, but who knows may even be worst). There are videos in YouTube which show you in true practical test - just search it.


Sad to say this is the Malaysia "norm".

Judging by my own experience going to 10 electrical shops giving me bullshit theory (RCBO no such thing, 30mA water heater, 100ma for socket etc) - I would say that this is so normal when wireman decide to also follow the "norm", partly also driven by customers who only wanted cheap.

This. Doesn’t look like got SIRIM

that one tipu cable. If u see the cable insulation there's nothing printed on it right? Or just PVC auto control cable without mfg name.
Clear violation of standards if used in residential 230V but they label as PVC auto control cable

Auto control cable is safe for low voltage 12V/24V in auto(mobile) use or control circuit.
It may not have enough insulation resistance for 230V or 415V.
Insides also likely to be recycled copper or not pure copper.

Fresh copper very pliable and can be twisted without breaking apart on the first time. Compare Caramay/Mega Kabel with any of the PVC auto crap
Price-wise also should hint something is fishy no?

Actual price for 2.5mm still >100, the 90 one is old price clearance stock
At 55 bucks its not like they got the copper stock half price...

Here is a snapshot from Suruhanjaya Tenaga's Water Heater Installation Guideline. Not just uncertified technicians, but even many developers are still providing new properties with 3-pin socket in the bathroom, which is very irresponsible. Let's remind one another to STOP using 3-pin plugs for water heaters, and connect the water heater directly to the main power supply (with the correct cable size depending on the water heater's power rating, refer to the next screenshot below).



If you are worry that removing the 3-pin socket will leave a hole in your bathroom wall, you can use a water heater connector to directly replace the 3-pin socket using the same junction box, as suggested by davidlow7 below, such as SIRIM / Suruhanjaya Tenaga certified water heater connector brands like STEC and CENTON. Here is one example from Shopee.


Use this table below to determine the cable size / switch you should be using based on the power rating of your water heater, as recommended by Suruhanjaya Tenaga.

Thank you sifus and gurus, now i can bath safer

Everything is working well, rccb, 20a, water heater is all good

What need to do next? Test it every month?



I have another question regarding ceiling led lamp, shld i open a new topic or just post here?

As long as it is a 10ma maximum sensitivity that is a good one.

Suggest to create a new thread for a new topic, but you might want to do a search if there is already an existing thread about the topic which you can leverage on.
