    Big C has the 3 liter box for B1009 but I have previously not seen that size.

    Seems you live back in time.

     

    As Kittenkong says, 3 liter Montclair is 1149 now at Big C, and the exact same price at every supermarket I have been, and has been like this for at least a month. It was 1009 prior to that,

    For some odd reason it seems

    not many expats in Thailand are aware of this simple and free method

     

    For some odd reason the majority of expats is not from the US, even the Aussie you were responding to isn't from the US, and this option is available only to US and I think UK citizens.

    It was yesterday.

    That mean it is old stock or do you think different shops have different price for mont clair?

    There are now newish cheap end brands that has fully imported no-fruit juice (non-orange tax lable)

    Color of the tax label has nothing to do with fruit juice added. Import is blue. Those cheap bottles have also fruit juice added and are still old stock price. Wait until new stock arrives

    Finally I designed myself a modification. Now I use a Honda blade what lasts around 30 hours and costs only 600 Baht. And also with this blade it is the upper part part (so the part what is far away from the grass) what disappears....

    But the difference is my area. I have around 30 rai, and use the mower at least once a week. So I expect that your blades last around 60 times longer.

     

    Let me see if I understand this correctly, you cut 30 Rai of lawn weekly with your Honda self traction lawn cutter, and your blade lasts 30 hours.

     

    I have about half a Rai lawn, and it takes me about 2 hours to cut it with my Honda lawn mower.

     

    So your 30 Rai must take about 60 hours, or a full week if you work 10 hours a day, to cut and you have to change your knife at least twice every week.

     

    I'm surprised you still have time left to post on this forum.

    Which is a US standard. The US in general, doesn't use front end RCDs, so random N-E links won't have any visible effect other than splitting the neutral current all over the place (not good).

     

    Thailand requires a N-E bond (MEN link) where the supply enters the property, it must be before any RCD protection (or the RCD won't stay on).

     

    With N-E solidly linked any surge on the N will go directly to ground.

     

    IIRC you have your own transformer with the neutral solidly bonded to ground at the transformer. Neutral is going nowhere significant on a surge front, if it does then you have bigger problems (like putting your roof back on).

     

    Daisy chaining the grounds, so long as you keep everything short, should be fine. The secret with surge suppression is to keep all paths as short and straight as reasonably possible.

     

     

    Thank you for the clarification, I was worried about the N-E in the DB since that is close to the appliances, but I confused the neutral  from the incoming feed with the neutral from the MCB's

    Yup, sorry about my tardy response, I have a day (and often night) job too :smile:

     

    No worries, but on closer look I decided to install 3 arresters anyway, because each arrester protects only the bus-bar it is installed on. At least that is my understanding.

     

    So is it allowed that I go with the ground wire from one arrester to the next one, and only from the last arrester to the ground connection in the DB?

     

    And I just stumbled on this, which made me confused about the N-E connection you suggested earlier.

    The Dangers of Neutral to Ground Bonding in Surge Suppressors

    Non-compliant Neutral to Ground Bonds
    A non-compliant neutral to ground bond is usually easy to spot. Open a distribution panel and look inside. All of the branch circuit neutral wires, the white wires, terminate on a common bus. All of the branch circuit ground wires, the green wires, terminate on their own bus. If these are interconnected in any way, a violation of the NEC exists.

    When we inject unwanted higher frequency current in the ground path, we are going to have this current wandering around the continuous ground path in a facility. This is bad enough at 60 Hz, but at 180 Hz and higher, the values of impedance change and parasitic paths are created inside the facility and interconnected equipment. If the cable interconnecting the network has a shield, then some of this ground current will split off and flow through that path.

     

    My understanding here is, but I'm gladly corrected if I'm wrong, that in a surge the surge arrester sends the surge to the ground, but since ground and neutral in the DB are connected, some of the surge may return to the appliances over the neutral wire.

    3 single P 30ka ~ 60Ka arrestors arrived today. The larger for in the big box outside didn't arrive yet.

     

    So to make things clear.

     

    I have 3 RCD's in the DB. First RCD get the mains live feed. Second RCD get's it feed from the first one and third RCD get it feed from the secong one.

     

    Q1 : Should I install an arrestor next to each RCD or is only one next to the one that get the mains feed enough?

     

    As you know the current arrestors are at the end of the bus-bar, so I have to move them next to the RCD.

     

    This may cause some wire shortages and ground connection slots in the DB, especially since I add one more arrestor this time, and if I can avoid buying a roll of 10mm wire that is appreciated of course.

     

    Q2 : Can I go with the ground wire from the first arrestor to the second one and  from there to the third one, and from the third arrestor to the connection point in the DB ?

    The arrestor should go as close as possible to the incoming supply in order to be fully effective and have as short as possible cable to the ground rod.

    If the lamps are lighting at all then they are polarity insensitive so it's unlikely to be the issue. Of course you could flip the ones that are "wrong" and see if it improves matters.

     

    It's actually only 1 light that has reverse polarity, and I had 4 lamps dying in the past 30 days.

     

    They came from China, you think that could have any influence on the failure rate :whistling:

     

    I had the local tv repair guy check one of the lamps, as I thought it might be the capacitor that failed, but he said that some of the led's were shorted.

  10. I have a circuit of 12 - 24VDC led lamps, but get many failures, which of course can be the lamp quality.

     

    However I measured and while it measures 23.5V at the lamp socket, the polarity is reverse to what it should be.

     

    Could this be the cause of the failures?

    Ah, such certainty!

     

    Imagine, just for a minute, that she hasn't left the country yet.  If that turned out to be the case, will you promise you'll be back for a comment...

     

    I'm not gonna make you wait any longer for my comment.

     

    If she's still in the country my first post still stands, because after all it was Prawit who gave the order to follow her, so it is his job to know where she is.

    i presume you mean request bail; whomever in the 'court system' that is responsible for accepting/rejecting such applications/requests must be very busy; reapplication after reapplication...and piles up revenue for the applicant's lawyers

    No, I was talking about policemen sentenced to death been freed on bail.

     

    http://t2.thai360.com/index.php?/topic/58387-kalasin-killer-cops-free-on-bail/

    Five policemen convicted of murdering a 17-year-old man from Kalasin were released on bail Tuesday by the Criminal Court. :surprised:

    A key witness, the teenage victim's aunt, said she would seek to extend her enrolment in a witness protection programme now that the convicted killers have been set free. :doah:

    Pikul Prohmchan, one of three key witnesses in the murder case, said she would petition the Department of the Special Investigation (DSI) because the release of the five convicts - three of whom were sentenced to death - could put her life in jeopardy. "I'm afraid that we might be killed before the convicts receive the capital punishment," she said.

    He should plan for a worst case scenario which includes a major drop in the value of his currency against the Thai baht AND minimal or even zero returns on his capital AND inflation above historic averages.  If he pumps numbers from such a scenario in to a spreadsheet and the spreadsheet shows that he will still have money left over at what would be a fair guestimate of the end of his life expectancy then he has passed the retirement in Thailand financial stress test.  If his finances don't stretch that far then he has a few decisions to make such as working longer, spending less etc. or simply taking the risk.

    As I'm not  Brit, this doesn't actually affects me, but you want to say that in let's say 2006 you took in account that the pound would be 42 to the Baht today?

    Former commerce minister Boonsong Teriyaphirom’s lawyer will try to seek bail for his client again.

     

    After your convicted and sentenced to 42 years and to repay billions, your allowed bail? So you can do a runner? 

     

    In Thailand you can get bail after you are sentenced to death for murder.

     

    Ask the 3 policemen in Kalasin who got bail the very next day.
