  1. the cause in my case is definitely the thunderstorm with the lightings ... not only me, also my neighbor thinks we all had some direct hit!! (who knows who is right?) this seems the reason. but only 5 of 21 breakers need to be replaced at my house ... it is just very strange and a new experience for me!!!
  2. thank you for your reply. I did it already (more than once!), also i did put the test button an the safe-t-cut ... I am glad having not more damage, only replacing a few breakers ...
  3. last night we had a storm with many nearby lightning strikes. after that some power circuits did not work anymore and I will have to have to replace a few broken breakers. the wierd thing is, the breakers did not tipping ... (why?) (i replaced one breaker, and it worked again ... now i need to buy a few more to replace all broken ones) one of my nighbor has the exact same problem ... 280516.pdf

    Chiang Kham air quality

    You can not smell Pm2.5 and the visibility depends on so many different factors ... I for myself trust my own Pm2.5 meters . I live only 90km away from chiang kham and we have at the moment for the AQI (PM2.5) 161 = unhealthy for everyone!! have a nice and successful stay

    Chiang Kham air quality

    Phayao shows only the AQI for Pm10 and not the AQI for PM2.5! Be prepared for a Pm2.5 AQi of 150 - 200 ... (Mask N95)

    some of this readings are the "aqi" for pm10 and not for pm2.5 (e.g. maesai ...). you can not compare pm2.5 with pm10 readings! "AQI" and ... µm/m3 readings are not the same!! be carefully not mixing up!! http://aqicn.org/faq/2013-09-09/revised-pm25-aqi-breakpoints/
  7. inside can be nearly as bad as outside .... have to use air purifier!!!
  8. many of the other readings are pm10 and not pm2.5 ...!!!
  9. I (chiang rai city) use these sites daily. please note, some stations measure pm10 instead of the more dangerous pm2.5! http://aqicn.org/city/thailand/chiangrai---gaia-station-03/ https://firms.modaps.eosdis.nasa.gov/firemap/?x=100.44374999999997&y=18.403125000000003&z=7&g=g&v=6&r=3&i=nw&l=ad,ct

    earthing system

    hi, does anybody know what we have to do with our fridge (only 2-pin)? does the fridge need earthing at all? ... we bought this one just about 2 years ago and it was not a very cheap one. thank's for any help motdaeng from the north If it's got a metal case then it probably needs a ground. Have a look on the back, if there's a screw with the earth symbol on it, connect that to the earth pin on your outlet or another ground source. Symbol looks like this:- i found the symbol with screw on the backside. i wasn't aware that the solution can be that simple. one problem solved, thanks a lot crossy!
