Anyone knows why my power trips even at the slightest lightning strike?

During one normal thunderstorm, it can trip for up to 5-10 times. My neighbour's power doesn't get tripped, while mine does.

Anyone can troubleshoot what component in the electrical system is faulty? It's very annoying when it trips when I'm doing something important on the computer. I want to fix this frequent tripping problem, I don't want to buy a UPS.

Thanks.

I think you misunderstood my problem, I strongly believe that there is a problem with the electrical system, causing the frequent power trips. Of course, I can just call an electrician over to take a look at it, but he has come here quite often and he did not mention anything about anything being faulty. So, I just want to get your thoughts on what could be wrong with the electrical system. As I've mentioned before, my neighbour's power doesn't trip when mine trips.

If I wanted to, I could go out and buy a UPS right now, but I want to get to the root of the problem. Buying a UPS, but still facing the frequent power trips is annoying. That is why I want to troubleshoot what is wrong with the electrical system first.

Yes yr circuit breaker is too sensitive. you can replace the elcb, it wont cost much. my house ELCB trips when very strong lightning but not all the time. Get a reliable brand, its very important hardware in yr home electrical system.

No harm if u spend more the get a good one.

Thanks for the replies guys smile.gif

Do you think that it's wise to ask my electrician to reduce the sensitivity?

U cant reduce the sensitivity but the replace the ELCB to a better reliable brand.

Ask him to also check your earth wires if all are good.

in my old house even the slightest lighting makes the power trip.

My house is the only house in 16 acres and is on a hill so i guess its normal for it to trip at slightest lighting. I asked my electrical technician and he said that its Normal for it to trip often during lighting.

Does it trip a lot lastime? or just recently tripping a lot?

This is because when the lightning hits the ground (open area) it feeds back to your copper grounding rods which is connected to your ELCB and therefore giving u a trip.

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.

That is actually good u know, having a sensitive ELCB, that will protect your household electrical appliances from getting fried (including your precious PC).
Still remember my neighbor ELCB are not sensitive, as a result 1 lightning took out almost all of their electrical appliances.

Hi Boon,... if it is too sensitive, I regard it as an overkill. It will not be protecting our equipment against overcurrent conditions and voltage surges anymore, it will instead contribute two undesired effects, namely :-

1) Unreasonably tripping the mains supply and causing us inconvenience to go reset it at the DB position.
2) Compromising certain functions oi the house when the trip occurs unnecessarily, eg spoiling food in the fridge, removing CCTV Security, etc,....

Hence, I believe it is more preferred to have an ELCB that trips ONLY upon ACTUAL 'danger' conditions, and not on all possibly 'danger' conditions.
