Hi all,

Recently just DIY a water heater installation.
I am not convince enough with the inbuilt ELCB water heater.

So decided to install another external ELCB to this water heater.

So how does the connection look like ?

ELCB 10mA

2 input top ( L is live , R is neutral ) ?
2 output bottom ( L is live , R is neutral ) ?

Just go the info from here http://electricalinstallationwiringpicture...n-pictures.html


Can any electrician / engineer confirm this ?

Thank you.

If you are not familiar with the electrical stuff, better to get an electrician to do it. Safety first

ELCB is place in the incoming. You put only for specific load? very wrong.

The water heater breaker are really good. Well unless you buy some unknown brand of water heater than is difference. You can test the water heater breaker frequent to reduce the risk.

L= live, are u sure the other letter is "R"

N=neutral

read carefully..........it should be "N" lar unless u buy those don't know what brand ayam elcb...

elcb 10mA/ 30mA normally install for those tank type water heater/ solar backup heater

my L means left side
my R means right side

incoming already installed ELCB. 30mA

But for this water heater, it is better to install ELCB 10mA before this heater.

mana ada orang quote left right for elcb one, the diagram on the elcb ada show the L/N connection mar, if u don't understand the diagram then PLS HIRE A ELECTRICIAN, won't cost much lar..


single phase 2P ELCB @ incoming should have the rating of 0.1A/ 100mA
3 phase 4P ELCB @ incoming rating should be 0.3A/ 300mA

30mA normally use for water heater Not incoming

If you don't know much of electric and current please skip some lunch use the money to hire proper electrician. You don't want to become Automan.

I instal an elcb before the heater too. I just don't trust too much on the heater electronic elcb. Electronic are fail faster.

30mA is not sensitive enough.

I recall seeing someone house having an ELCB installed just for the water heater. Most likely he was also concern on the reliability of the built-in ELCB.

either that or its a backup

i went to some friends house/home stay/rented apartment

some of them are using those really really old water heater..

are their ELCB still working ? , sometimes worry if will get electrical shock when bathing half way...

just curious what will happen when ELCB fail ?
