Earthing problem? Or your ELCB is too sensitive.

Hmmm... I'd say still check though. ELCB going off too often is usually not a good sign. If it's tripping your power supply too often, there's a stray current somewhere in the house. Usually means frayed wiring somewhere, an electrical wiring is getting soaked by the rain or the entire system is not grounded well to ensure the stray current gets into the ground.

BTW, if the power supply is tripped too often, it's also not good for electronic stuff. They can't handle the shock of no power. >.< Electrical stuff may last longer though but still, not a good idea to have too much tripping.

Is your Mains DB outside the house? Heavy rains + thunderstorm usually means heavy winds bringing in the rains. And usually, house DBs may/may not be rated for outdoor usage i.e. not water-tight. Especially older systems.

Lightning can trip the Mains DB but only if lightning stirke was very near your house. If it's not near your house, shouldn't trip. By near, I mean that you literally feel the entire house shaking when the thunder booms.

The house I'm currently in is old (built in the 1970s). Only time the ELCB trips is when the above case happens. Else, no problem. Circuit Breaker boxes are all inside the house and not outside. ELCB and MCB are more than 20 years but still seems to work. *SEEMS TO*

u're lucky. a friend of mine in bangsar was complaining about 219.94 last nite. he said that 60.49 was fast for me.

dunno what the heck streamyx is doing.
