Extension Cords – Where are they

from Gary
Very good info in coolthaihouse. One question. Why is it difficult to find extension cords in Thailand? Like 25′ or 50′. Have house in Bangkok and have searched everywhere. My Thai wife and I have been using three interior cords with shut offs to pump out the water in fish pond. Should I just take over from America a 120 volt heavy gage? Any problem?

Editor: I was just in the HomePro here in Pattaya and they have a good selection of extension cords. They have various gauges, from light to extra heavy duty. The sizes ranged in length up to 20 meters. I don’t think you need to bring any over, just check out the HomePro in Bangkok……



    Do be carefull when using ‘coiled’ extension cords, eseciallly very long cords.

    Because of something Electrical Engineers call “Induction” coiled cables can give rise to a fire risk.

    What happens is, the coiled cable acts like an electromagnet, when electricity passes through a coiled cable it creates a magnetic field, and the magnetic field generates electrical currents and heat in the coiled cable.

    The more coils you make the more this effect occurs, also the more electrical current you pass down a coiled cable, the greater the effect.

    The worst is a lot of current down a tightly wound cable – if the cable is also coiled in a plastic housing there will be less air (cooling) getting to the coil, increasing the risk of over heat and fire.


    Use a lead that is just long enough (not a long coiled lead).

    If you must use a long lead, always unwind it off the drum so you do not get inductive heating.

    If the insulation of an extension lead is damaged (say from being trapped in a door) disgard it and get a new cable.

    Be careful not to leave cables run where they can cause tripping hazards.

  2. Too bad thai builders here don’t put enough outlets in housing, even new housing, so that you don’t have the danger of extensions cords. It seems like they build houses and just expect you to use extension cords. One place to get almost anything like extension cords and tools is the big tool market open on the weekends in Bangkok near China Town.

  3. I probably should have said thai architects don’t put enough outlets in the houseplans. Builders only build what they are told to build.

  4. Outlets/sockets. I have just had a meeting with my technical drawing man who’s drafting the plans of my house. I went through every room with him and my wife and we agreed on all sockets, all light fittings and all taps (faucets) and so on. I think he was shocked at the number of sockets I KNOW we will need.

    The alternative is a lot of remedial work later on or extension cables all over the house … not doing either!!

    Because I am a Brit and my family will be visiting from the UK from time to time, I am going to install a UK square pin double socket in every area of the house: about 1 UK socket for every 4 or 5 Thai sockets. I haven’t seen UK sockets for sale here but I am going to the UK next week and will buy them there … unless someone can tell me where to find them here. I know I could buy adaptors but a) why waste money on them and b) Borrowers always manage to borrow such adaptors!

    Here is BKK at the moment but the house will be near Surin,


  5. I was pleasantly surprised to find triple sockets for sale in the UK. I had never seen them before … got them in B&Q!!


  6. you can buy universal sockets in thai whatsadu (please excuse the mis pronounciation) we have used a few of these in our project. they take all types of plug from uk through to australian and european. they were quite reasonable
