mcfan Posted August 21, 2014 Share Posted August 21, 2014 Hi all, Hope some one can help. Wife built a small house at the rear of parents house using a local thai builder (up country). One bedroom,no hot water or air cond, He also ran the cables from the meter pole to her house using Bangkok cable 750V 70c PVC THW 16sq mm TIS 11-2531 table 4. This I read on the cable,inside it has 7 copper strands. Approx 30 meters long The electric company has come to put the meter on and said no good wire not right. Is this correct if so what size wire should she have ? It has been two years since the house was built and she has been using a cord from the front house until now.

gerry123 Posted August 21, 2014 Share Posted August 21, 2014 just as a thought would the local P E A not be be good for advice as to acceptable spec cable ?? Link to comment Share on other sites More sharing options...
mcfan Posted August 21, 2014 Author Share Posted August 21, 2014 Yes if only it was that simple, that's why I asked here. I don't speak thai, she won't ask. Builder said ok so must be ok. ( guess its a Thai thing ) Link to comment Share on other sites More sharing options...
Crossy Posted August 21, 2014 Share Posted August 21, 2014 What size meter are you having, PEA won't put anything bigger than a 15/45 on 16mm2 cable (which should be more than adequate for what you have). You do need to ask exactly what is the issue, you can't just guess. Link to comment Share on other sites More sharing options...
ChongBoy Posted August 21, 2014 Share Posted August 21, 2014 THW is not an outdoor cable. You need NYY which can be used without any conduit or piping. Link to comment Share on other sites More sharing options...
ThaidDown Posted August 21, 2014 Share Posted August 21, 2014 THW is fine for overhead use (ie post to post). NYY is used in ground with or without conduit. Link to comment Share on other sites More sharing options...
ChongBoy Posted August 21, 2014 Share Posted August 21, 2014 From Bangkok Cables product catalogue which is on my desk in front of me... "THW Application: For building wiring, installation on insulator or in a race way, DRY LOCATION" "NYY Application: For installation exposed or in a raceway, dry or wetlocation, or direct burial in ground" The guy said the wire was not right so maybe he is being strict on the rules. Either cable works fine for what op needs. Link to comment Share on other sites More sharing options...

You do need to ask exactly what is the issue, you can't just guess. Didn't get to the meter size, I think they my have just looked at the diameter of the black cable thinking it was the alloy one and said no.Would be happy with a 15/45 if the wire is suitable. Her brother has a 5/? For his grass hut, light , fridge and big tv. My guess a 10/? Would be ok the 15/45 great. Link to comment Share on other sites More sharing options...

Crossy Posted August 21, 2014 Share Posted August 21, 2014 Whilst THW is not officially an outdoor cable it is regularly used as such when mounted on insulators (naked copper would be OK too). No issue here, we have 16mm2 NYY from 15/45 meter to house, it was installed by PEA. EDIT Do you have an RCD (Safe-T-Cut) and 3-pin grounded outlets? If not that would be a fail for a new PEA connection. Link to comment Share on other sites More sharing options...
mcfan Posted August 22, 2014 Author Share Posted August 22, 2014 EDIT Do you have an RCD (Safe-T-Cut) and 3-pin grounded outlets? If not that would be a fail for a new PEA connection. Firstly thank you for taking the time to answer my questions . I have spoken to my wife again,PEA came to the property to connect a new meter to her brothers hut, he was also using the main house meter ( illegal ). I have had a look at the pole at the front and their are 4 meters all 5/15. She was not on site when PEA did the brothers meter. She is sure that they never looked in the house, all they looked at was the two wires that the electrian fitted to the pole where the meter will go next to the others. The ends of the wires have black tape covering them. I have included photos of what we have. I think the guy did not see we used copper cable NOT the alloy that all the other meters have feeding them. As we are returning to Australia next week I will have to follow this up next trip in January 15. Link to comment Share on other sites More sharing options...
Crossy Posted August 22, 2014 Share Posted August 22, 2014 You have:- 16mm2 cable (copper) 63A incomer RCD 3-pin outlets I can see no reason whatever that PEA wouldn't hook you up on a 15/45. EDIT I have seen reports in the past where the connection guy wouldn't hook up the meter as the cable was too BIG. I wonder if this was the case here as he was going to fit a 5/15 which would normally hang on 10mm2. Link to comment Share on other sites More sharing options...
ChongBoy Posted August 22, 2014 Share Posted August 22, 2014 Sorry, but the PEA guy said he had the wrong cable therefore there is a reason for the PEA to not approve. I can name lots of copper cables that will work but the real cable to use and get approved is NYY. Crossy has even said he has NYY in his house which is the legal choice. I don't see why confusing the OP helps . Link to comment Share on other sites More sharing options...

Ok if I need to replace the cable what should I use to make sure I comply and exceed thai standard? Or is it better to get PEA to do the job?

Crossy Posted August 23, 2014 Share Posted August 23, 2014 Safest (but not cheapest) would be to get PEA to do the job. 2 Link to comment Share on other sites More sharing options...
mcfan Posted August 23, 2014 Author Share Posted August 23, 2014 Cost wise we have already paid the builder for the job, which appears to have used the wrong cable. 2years on just for a laugh what is the guarantee over here. Sorry had a seniors moment. Up until we made final payment I guess. Does the PEA charge per meter run or just a total cost to replace. These are just questions for general information. I will contact them when we return next year. We have gone back to using the extension lead arrangement from the front house for now Link to comment Share on other sites More sharing options...
wayned Posted August 23, 2014 Share Posted August 23, 2014 Before I would change anything I would get PEA to come out and tell you exactly what is wrong. If you think that it because you are using aluminum then show the guy that you are using copper! Sometimes my Thai wife drives me crazy as she refuses to ask why or even directions if she's lost. She tells me that she won't ask because the people will think that she is stupid. I tell her she is stupid for not asking and WWII starts all over again! 1 Link to comment Share on other sites More sharing options...

RichCor Posted August 23, 2014 Share Posted August 23, 2014 Safest (but not cheapest) would be to get PEA to do the job. Yep. Came here to say this. I usually just get fed up and do an end-run around the issue by directly contracting PEA, or locate a willing off-hours PEA Employee, to just do whatever will satisfy the requirement/in-house politics, to get the power turned on while maintaining safety. It probably costs more money to do it this way but it does get done and usually everybody ends up happy and on to the next thing on their list/agenda.

mcfan Posted February 21, 2015 Author Share Posted February 21, 2015 As promised the Final update and connection of electricity. History wife arrives 15th Dec 2014 village.Returns to electric office with a piece of cable, shows someone. Yes that is fine,gets put on the list, very busy. I arrive 20th January still waiting. Due to leave Thailand 18th February so around the 10th of February we call past the office just to check. Still busy lots of people waiting we are on the list. Friday the 13th unlucky for some not us the meter is fitted 15amp cost around 4600 baht ( counting of light and power outlets)had a bearing on cost?. Extra info brothers grass hut connection cost 560baht for 5amp. Wife a litte heated when they spotted me they also wanted beer as well. Anyway still don't know why they said no the first time,I still think it's because they assumed the cable was alloy and to thin. So all happy, sorry final question from the wife "will the electric be more expensive because we have 15amp" I think I know the answer but I said I would ask ok Thanks to all who gave advise,and another happy ending in Thailand Link to comment Share on other sites More sharing options...
Crossy Posted February 21, 2015 Share Posted February 21, 2015 Thanks for the update If you have a permanent supply, power is about 4.2 Baht per unit for 5/15, 15/45 and 30/100 meters (the rate is variable and goes up with usage). If you have a 'construction supply' you get charged roughly double the standard rate. EDIT If you could post a photo of the markings on the cable that was finally OK it would be most useful.

mcfan Posted February 21, 2015 Author Share Posted February 21, 2015 (edited) EDIT If you could post a photo of the markings on the cable that was finally OK it would be most useful. Hi Crossy thanks for your interest. We are in Australia so a photo will happen when we return to Thailand in October ,sorry. The cable has not been changed so the markings are the same as my earlier posts. Bangkok cable 750v 70:c. PVC THW165sqmm TIS 11-2531. Table4. The cable is black coating with 7 copper core/strands Edit yes it's a permanent supply,the house is finished.
