  1. Thanks. I used the calculator again and it gives me 35mm2 for 40 Amp, 180 meter. And 25 mm2 for 30 Amp, i.e. 6,900 Watts. We will not have air conditioned, but the main appliances that will require some power and work (possibly in the same time but sometimes not) will be : refrigerator, microwave, a simple shower heater, air purifier, air cooler, usual power tools and ordinary concrete mixer. Total: about 6000 - 6500 Watts. So it should be fine, even if we need to use more power in the future, we will have cold showers for a while (saving 3500 W) ????
  2. Thank you Crossy. yes I got your point and I asked my wife to ask him two times about that. I also didn't like/understand his answer, it doesn't really make sense. The other thing is that your Doncaster cable calculator has many type of cables and other parameters to consider, and I don't know which one he will use (or could use), and I don't imagine at this point of the discussion to ask him more about his cable. Maybe from your experience you have some idea of the usual cable they use ? or which one did you select to say that for 180m and 40 A, 50 mm2 would be required? I appreciate your help ! very nice.
  3. Sorry, I misunderstood the information I got. This price (35,000) includes also 2 poles installed by PEA on the public road. Actually, the person recommended by PEA (business card) is a PEA staff working as 'private freelancer'. He came to our land and here is his quotation (15/45 Amp meter). We managed to reduce the distance to 160 meters as we prefer to connect to a warehouse, then connect the rest in a cheaper way (yellow pipes underground) to the house and other buildings: - Six 8 meter concretes poles: 6 X 3,900 bahts - Cable (Aluminium, 25 mm2) 180 meter X 2 X 30 bahts - Other stuff 7,000 bahts So, total is 41,000 bahts for 160 meter. I argued about getting a cable with higher diameter (voltage drop). The guy answered that it was not possible for this kind of installation/poles, and if I really needed, I should request PEA later to increase the power....Let's see...
  4. Hello everyone, We contacted PEA to connect electricity in our land (15/45 amp). The house is now built, we are asking for a permanent meter and the installation to the house (about 200 meter from the public road, quite long as the access road is about 170 meter long). The officer had a look on the Chanote, another guy came to see our land one week before. He said the first step was to contact a private contractor to install the cables/poles between the house and the land entrance (public road). Then, PEA would check that work, and install the meter. Even though I often heard it was better to contact a private company to deal with the installation on the land, cheaper and in some cases more reliable, I was very surprised, especially because the neighbor did the same last year, and PEA installed the 2 poles necessary on his land. My questions: 1. What might be the reason to automatically give the job to a contractor and not trying to get the job done by themselves? Anything to worry about this practise? 3. We will meet the contractor next week, so to check the quotation he would give, what is roughly the cost to install electricity along 200 meters. We live in the countryside in Chiang Rai province. What are the other costs? because they just told my wife the meter cost just something like 800 bahts but I always heard of a deposit of about 30,000 bahts. Thanks for your help ????
