You are right on voltage spiking issues. But then Malaysia are having the highest power reserve in this world.
And each year there will be cases of house hold user's electric appliance being fried especially between 9-11am.
I believe many do have kena fried the electric appliance.
But for my case it a bit strange.
The aircon have been ON 7/11 for 19yrs, never fried before. It only have main MCB to ON/OFF.
The fridge as you know run 7/11. Same never fried before.
But the thing that always fried is the PC thing. Like modem, router, NAS etc.
1 thing that have to takecare is the voltage range. Most of the time, TNB voltage in the high side. It is like 240-250+V. Never been lower than that. So some electrical/electronic voltage range at 220V (china thing) I will be very carefull to buy.
Another thing is the switching spark. My switch socket constantly require to change when there is some abnormal during ON/OFF. It can be detect by some phenomenon from the electrical.
