I've asked an electrician, but he says it's normal. I don't believe him, because when I look out the window, the neighbours lights are all on. And it happens way too often. Half them time we hear thunder, the lights will go off. It happens even when the lightning is more than 1km away. We're reduced to waiting for the thunderstorm to pass. There's no point flipping the switch on the ELCB because it will simply trip again.

rattan, so what is a good brand? which shop should we go to if we're around the KL area.
