Incoming power -> New(Safety) 25 A, 10 mA RCCB -> Water heater, Is this OK?

Cannot standalone RCCB.
RCCB must pair with a 16A MCB.

Opssss. My bad... Should be

A) Incoming power -> RCCB 63A/0.03mA -> 25 A, 10 mA RCCB -> Water heater. or

B) Incoming power -> RCCB 63A/0.03mA -> 25 A, -> MCB 16A, -> 10 mA RCCB -> Water heater.


As per ST page 11 drawing. To comply A or B?

B) Incoming power -> RCCB 63A/0.03mA -> MCB 16A, -> 25 A, 10 mA RCCB -> Water heater.
Note the correction made

Why do you still want to go for this "safety" brand? Is it not obvious to you that it is cap ayam? If you feel that you and your family's life is not worth so much to get Hager/ABB, then at least get Maxguard which is cheap and known to be "decent".

If on the other hand if your electrician insist on using this brand, then just change to another electrician. Or go and buy yourself and get a better electrician to install.

My comments may seem harsh, but you made the effort to come to a forum to ask questions and people gave you good answers but it is mind-boggling that you still choose to be ignorant.

Thanks for your advice 👍
As per advised by forum members, I've requested items mention below

mains 63A/0.03A [30mA]
-- Hager CD263B = 63A 2P 30mA; or CDA263U
Water Heater 10mA RCD [need to pair with 16A MCB]
- HAGER CC216B or CC225B /  2 Pole RCCB 16/25A 10mA

Luckily the electrician willing to change the RCCB .
Now waiting for him to change. Hopes no more hiccup. 🤞

how to know our house single phase or 3phase??

for new house can i request drawing technical from developer?? because few additional cable i wan to kontraktor hack wall

When u submit TNB deposit u can ask ur developer, or just post a clear pic of DB box.

Most new property esp landed are normally 3 phase ready now. If you want 3 phase, you make an application to tnb, otherwise it will be single phase.

My current place about 13 years is 3 phase ready.

Ohhhh

Seems my electrician can not source the HAGER CC216B or CC225B / 2 Pole RCCB 16/25A 10mA.

Anyone know where to purchase it. Thanks

not all electrical shops carries them cause hager rccb10ma not cheap.
where are you staying?

Shopee got many electrical stores selling online (CPE, KJE, Edaran)

My god, really have to spoonfeed ur electrician.

Yeah.. That's the reason mention by the electrician. Out of stock
I'm near KL area.

Any prefer physical shop around KL that sell Hager?

Yes, quite a hassle. When i requested for a better quality/brand RCCB with 30mA and 10mA. He seems to be aware.
He brought up Hager brand and says that's it just slightly more expensive than other but reliable.

Then he bring the Safety(brand) to install. 👀
Luckily he's willing to change. Later inform me that one of the RCCB are out of stock and don't know when the stock will arrive.
Headaches 😩

Any prefer physical shop around KL?

There are a few Electrical shops in Puchong Jaya (same row as Restaurant Hee Lai Ton) selling Hager ABB.... you can try...

I used to buy there for my Hager 10mA RCCB but then since I know how to source online now (as they are usually cheaper) I stopped going there.
