The newer development's usually yes..

It is a mandatory requirement to have the water heater wiring connections to the guidelines of the suruhanjaya tenaga but some installation are not tested by the responsibility developer's consultants thus the owners need to be aware of this.

You need to do it yourself. Thus the need for a competent registered wireman with the correct test equipment.

The main issue was the death's of home owners in apartment with their water heaters installation protection not working..

You only hear from the published reports but actually many more happened but not reported..

Maybe. Unless you test it yourself or you trust the developer with your life. Your choice

The test equipment is an RCD tester.All three wires (live, neutral and earth) are connected to it. The 3LEDs on the tester will lit showing a good live, neutral and earth connection.
. There's a test button on the RCD tester

Press the test button.

The water heater RCD must trip without tripping out the main RCD and the LCD display will show a tripping time in ms(milliseconds) with the leakage to earth current in mA(milliamps). The readings should be less than 200ms and 10mA.

Have your water heater RCD tested by your wireman and have it recorded on a test report with your wireman's PW number and signature.

Sleep a little easier knowing that your water heater electrical connection will disconnect if there is anything wrong with the water heater and not harm/kill anyone.

Any 13A socket in the bathroom should be similarly tested to make sure it complies to the ST guidelines.

Hope this helps.

Yes but that device can't test the wire size and the mcb or rcd size connected to it.

And the 13a socket is a no no for any water heater

Yes, however some homes have a 13A socket beside the bathroom washbasin.. usually those higher class landed properties..

I mean if the 13A socket is installed within the bathroom then it has to be protected with a 10mA RCD to comply to ST. It is a mandatory requirement.

Might as well change it to direct connect to water heater as per regulation.
Even changing to a 15a socket is better than 13a socket. The fuse in 13a plug will keep on burn out.

You misunderstood.. the water heater is on a 20A double pole neon switch outside the bathroom.. only the wiring terminal from 20A switch to water heater location is present.

I meant some bathrooms has an additional 13A socket beside the washbasin (for hairdryer or shavers, whatever). It is this 13A socket which has to be protected..

Hopefully that's clear..

yup. clear.

but i dislike socket in bathroom. most people don't do it properly with water proof type socket.........heck some even don't have a on off switch for socket

hi, the developer provided a socket for instant heater (looks like 13A) but if i plan to install a storage tank heater, can i relocate the existing point or i have to wire another point direct from mcb? thanks in advance!

Hi all.

I received this quotation from the contractor. Looks expensive or this is standard rate? What do you guys think?

Thanks.

Lighting point is the point connected to the light fixture or the switch?

You can just route the cable to go up the ceiling for the storage tank but usually you will need to hack the walls to install the heater pipe to go to you mixer. (This is assuming no heater pipe was installed by the developer)

light fixture

Dear all, any reliable and price reasonable electric wiring contractor to intro, area = kl. Thanks.

Hi, I see your previous post with 37 lighting points with RM4625, which I feel quite high. May I know is that come with LED downlight?

Hi guys,

For looping of LED downlight in living room, let says 1st switch on 4 downlights, 2nd switch on another 4 downlights, normally how much cost of labor charge to supply the point and install the lights?

Yup included. But still very expensive. Hence I didnt proceed with him.

Hi.

I'm planning to do new wiring for my hse.

1) 13amp power point
2) Lighting Points (downlight)
3) Ceiling fan point
4) Water heater point
5) Aircon wiring
6) Armoured cable


TIA.

Hi,

I am in the midst of renovating my kitchen and had just had the first fix electrical wiring installed.

The pricing is dependent on the cable length, cable brand, cable thickness, hacking work required, PVC & conceal work, ‘looping’ or direct cable from the distribution board so it does vary from house to house. Might be better to ask several electricians for quotes.

PMed you mine.

Hi may i know how much for u to install the storage tank heater? my bathroom has the same design as urs and to utilize the rain showerhead i cant install instant water heater...
