Where are you located?
Shopee got 10ma RCD


M using ABB 10ma 25A RCD for the 10mA leakage protection coupled with B16 MCB for the overload protection at 16A.
The RCD is not meant for overload protection - for that you need a MCB. In other words you cannot have the RCD as standalone.
This setup consumes 3 slots in the DIN rail.

RCBOs combine this into one package (leakage protection + overload protection) into one slot single unit but it costs more.



At full load max heat (3300W heater) it consumes 13.77A, just under the 16A capacity of the MCB (86%).
Cable is 2.5mm stiff wire installed by developer + 50cm short length of flexible 3 core Fajar Cable installed by me.

Do note that you might need to use a bigger MCB if you have a >3.3kW heater (nowadays seems like quite a lot of 3.6 / 4.8kW models)

U can try Camar Letrik (road behind 3 2 square leading to sea park)

Nowadays noone use ELCB (dinosaur liao).
Standard is using MCB+RCCB 10mA coz more economical but this usually takes up 3 slots total in DB
Atas solution is using RCBO (= MCB+RCCB in one slot), more compact, price also more atas

No requirement to place it immediately outside bathroom. Even Sharp manual also puts in DB box SharpWH Manual
This will make whole circuit protected rather than just the few feet inside bathroom.

You will need to connect the RCCB with both wires Live & Neutral of the WH circuit.
Also the L of WH need to be connected in-line with either 16A or 20A MCB depends on your wire size and WH wattage.


Should get a good brand 10mA 2-pole RCCB - ABB Hager Schneider - all which are available on pee pee.

also loose cable (4mm min red/yellow/blue + black) of 1m length each to make the pigtails

Installed mine myself. https://forum.lowyat.net/topic/2954371/+308#
Beware of Live electricity. Isolate everything before starting job. Check test pen make sure its working (when live). Check with test pen after isolate to ensure no electricity.

Beware of overly cheap RCBOs in the market. Got fake products.
