Hi, thanks for the reply.

1. Yes, both are power strip surge protector.

2. The power trips is on rccb.

3. The aeon power strip I think is surge stabiliser, no led light, only one button that always on. Can't see the brand, only can see ADAPORT and MAX LOAD NOT EXCEED 3000W. But it has sirim sticker.

4. Belkin power strip has 2 led light, protected and earthed, both lighted. My pc, monitor, printer, phone charger and battery charger connected to it. Yes, this cause the trip, once I unplug from the wall, nothing happen. Can't leave it in the socket when thunderstorm. Sure trip.

5. Yes, without belkin, no trip even a strong lightning.

6. Yes, my old "forgot what brand" power strip surge protector also can cause the trip when thunderstorm, but not as sensitive as this belkin. Belkin one is guarantee trip when lightning. Even a small lightning. Old one at lease thunderstorm with strong lightning only trip.

7. House is 13 years double story. Landed.

Hope these will make it clear. Its really annoying, I can't use pc when raining.

And thanks again for the help
