Hi.
Welcome to Schneider Electric Easy9 RCBO tutorial.
I'm Jia Ying and together with me, Mazliazhar Abdul Latif,
senior product marketing engineer for final distribution.
Before we start, Mazli--
Yes?
Could it-- please explain to the audience what is RCBO.
RCBO is a device that protects against electrocutions.
It consists of two components into one, which is MCB and RCCB.
Its function is to detect leakage that occur
within the inside the electrical system internally and externally.
Where does RCBO need to be installed?
OK.
RCBO [INAUDIBLE] needs to be installed as an additional protection
for the water heater.
Normally, you can find it in the bathroom, or we call it wet area.
Why do we need RCBO?
OK.
Recent cases of electrocution that occur in Malaysia
prove that ELCB integrated inside the water heater
do not provide full protections.
If there is a leakage that occur from externally,
it will not protect the person who are using the water heater.
And plus, a 10-milliamp RCBO protection is a requirement under Electricity Act
1994, which mean in the installation of old or new of water heater,
you need to add 10 milliamp RCBO as a protection.
Well, there's a very good information for you and me.
Thank you, Mazli.
You're welcome.
Next, please stay tuned for our next tutorial on how to install RCBO.
From this video, you will learn about preinstallation checklist,
recognize the MCB that supply or connect to the water heater,
step-by-step to replace the MCB with RCBO, correct wiring of the RCBO,
test the RCBO functionality of the installation.
Before we start with the installation, please make sure
that the RCBO that you bought is a 10-milliamp protections,
25 amp current rating, come with a SIRIM label, and also an A-type protections.
Please also ensure that you have two type of termination
on the incoming and outgoing.
Next you will need two cables for the installation.
Red is for [INAUDIBLE] installation.
Black is for neutral.
Also a proper type of screwdriver to tighten and loosen the RCBO,
and finally the test pen which you use to ensure the power availability
has been cut off after you turn off the main supply.
Now we have gone through all the checklist that
needed to do the installation of RCBO.
So let's see how we do the installation inside the distribution box.
First, open up the distribution box that cover your MCB
and RCCB inside your house.
Second, identify which MCB are supplying to the water heater.
There is three type of detection that you can do.
First, you must directly categorize or label
at the cover of the distribution box.
Or it was label directly at the MCB.
Or the third way is you turn on one by one the supply which
are supplying to the water heater.
Next after we identified which MCB are applying to the water heater,
you turn off the MCB.
You turn off the main supply of the breaker.
Next for safety purpose, please use a test pen
to check the power availability at the outgoing
and at the incoming of the breaker.
Next, using a screwdriver loosen the cable of the MCB
that connect to the water heater.
Then take out the MCB from the distribution box.
It is required to rearrange the position of the MCB
and install the RCBO to the far-right side of the [INAUDIBLE]..
Use two type of color cable to connect to the incoming of the RCBO.
Red is for power and black is for neutral.
After we insert the cable into the RCBO terminal,
tighten the cable to ensure it fits perfectly to the terminal.
Use the same cable that connect to the water heater
and connect it to the outgoing of the RCBO.
Red is for live.
And black is for neutral.
And then tighten both termination to ensure the cable
fits perfectly to the RCBO.
Connect the earthing of water heater to the earthing bar of the distribution
box and then tighten the screws to ensure it fits perfectly to the bar.
Some [INAUDIBLE] installation are sharing neutral cable.
So it is advisable to pull a new cable directly to the water heater.
Once the cable is securely tightened, turn
on the main power of the MCB, the RCBO, and finally the water heater.
Press the test button on the RCBO.
If it trips, the installation is OK.
If it's not tripping, recheck the cable termination--
if it's connected properly.
Now your water heater is protected with a 10-milliamp RCBO.
Thank you, Mazli, for the tutorial.
You're welcome.
Before we end this tutorial, please take note on the following key points.
Ensure you install 10-milliamp RCBO for water Heater.
Ensure you buy RCBO that is approved and certified
by Suruhanjaya Tenaga and SIRIM.
Ensure that the cable connected to RCBO is correct termination
and properly tightened.
Always test your RCBO functionality by pressing the test button
minimum four times in a year.
RCBO should be installed by qualified electricians.
Do not try to install it by yourself.
Thank you very much of your time.
And we hope this video will help you understand
on the installation of your RCBO.
And remember, Life is On.
And safety starts with you.
