some Q s to get a clearer pic of your situation .

1. the 2 surge protector here are those power strip/ with surge protector ?

2. is the power trip s is on the RCCB unit in the DB box or ??

you said CB trip. note CB do NOT trip during lightning . in normal case. and CB=MCB is the correct name. MCB usually trips at short circuit.
the RCCB is the one that trips . mean the whole house lose power .
if MCB trips , you still have main power to some part of your house .

3. my guess the one from Aeon the protection may not be working . has it got a PROTECT LED indicator ?
if this is some ahchong brand ..then the above is true. my guess.
will help if you know the brand , or just paste a pix.

4. the belkin power strip has LED Protected right ? is it lighted ?
what electronics is connect to this strip. ?
if this is the power trip cause , how did you confirm ?

5, Are you also implying that without the belkins ( unplug ) you will not get any more power trips ?

6, Before you start use/buy the first surge protector mention in ur msg. Did you have frequently power trips whole house ?

7. How old is your house. Landed ?

cos the issues/problems are still valid and relevant today

i am sure many users are suffering in silence. cos lack of support and info to fix this .

from your info.. point 5 .

1. if i understand correct .. you are saying if you totally unplug the belkin from the wall / mean pc is disconnect from power ... you will not experience any power trip .
is this right ?

for now i suspect the PC has high leakage when a surge hits. / means its leaks current
the belkin will also divert current to ground .

if the total leakage ie , pc + belkin s exceed 100mA . The RCCB will trip.

one way to check if the belkin is really out .
is .. keep it plug in the wall socket but unplug/ remove all the pc , display , etc from the belkins .

mean the belkin is plug to wall but no load .
see it this test will trip the RCCB . if it does not trip ...then you can say the PC is leaking much current .


2. if you have a digital multimeter . can you measure the AC voltage at the wall socket . Neutral to Earth voltage .
this value is an indicator if you have earth grounding issues.

yes a SPD installed before the RCCB will suppress the power surge and bring the current to your earth rod ground.

today around 6pm around puchong area have a big thunderstorm as sure some there will have power trips.

That note that a ELCB / RCCB cannot save your electronic from being damage by lightning Surge.
they are there for human life protection .
the mechanical trip is too slow to stop a lightning surge typically 50 uSec .
response time for RCCB is around 30mSec.
