I don't see any developer in here that have install surge protector for your house. Even minimum level. Or an expensive bangle.

Yes. it help. That is already few experience that my belkin surge protector did do the job. While also have bad experience which I didn't use the surge protector.

Majority of the lightning is not direct strike to your house. It come from the line. Any line that have voltage running currently during strike.

Your house still no line? There is also others like Cal lab that does a good job too.

AV equipment also need to protect. This are sensitive equipment.

I plan buy belkin protect AV equipment.

Yes they install and conceal in the building itself, I have seen their work, but because the cable size they use is too small so when lightning strikes it cannot withstand such immense power going through therefore doesn't serve any purpose.

How about this? Can protect?

For surge protection, they only seems to install in big bungalows, for normal house they wouldnt bother

THere is no corelation between incident and new housing area. There are only corelation between incident to location, building height, protection level and maintenance.

Location = Malaysia has at least 200+ lightning day per year. Certain area in MY are more prone.

Building height = the higher you are, the closer you are to the clouds where lightning originated.

Protection level = look at Faraday cage....ESE is not reliable despite whatever the suppliers claim. Go Singapore NationAL Science Centre to check out the effectiveness of a proper Faraday Cage... Protection level also includes the three tier surge protection level.

Maintenance = Seen anyone maintain those lightning protection system or SPD?

Take note that the SPD is max at 40ka
Would recommend at least 80 ka

Should be ok la. Till your next equipment KFC. 

How much is this?

If FOC, ok la...the blu/test button is on the ELCB (Earth Leak Circuit Breaker). Recommended to push the button monthly to ensure that the eLCB turns off. If you press the button and the elcb does not cut off, time to change a new one.
