rawhod Posted September 19, 2017 Share Posted September 19, 2017 What are the current PEA regulations for the private house mains feed from the 15/45 meter to the house? Can you still suspend the wires over-head or do they have to be located in an underground conduit? Link to comment Share on other sites More sharing options...
bankruatsteve Posted September 19, 2017 Share Posted September 19, 2017 It's quite simple to find out: just ask your local PEA. Some, including mine, will not connect to underground. Link to comment Share on other sites More sharing options...
rawhod Posted September 19, 2017 Author Share Posted September 19, 2017 Thank you... I have spoken to the PEA and it is still permissible to use overhead mains feed in our area. Link to comment Share on other sites More sharing options...
bankruatsteve Posted September 19, 2017 Share Posted September 19, 2017 Also be sure to ask PEA size and type of cable they require. Some will only take Cu, others want Al and to a specific size. There is no national standard for this that I am aware and the local PEA's do differ. Link to comment Share on other sites More sharing options...

He said 16mm THW copper is OK for down-comer and over head, but 16mm NYY copper must be used for underground. Link to comment Share on other sites More sharing options...

Sounds pretty ok to me In reality I doubt PEA are ever going to outlaw overhead cabling except, possibly, in areas where the main supply is underground.

SteveB2 Posted September 19, 2017 Share Posted September 19, 2017 Hi Rawhod, My company has just completed (and had PEA approved) a quite complex SME electrical installation. Check out the attached Thai wiring regulations given to us by the PEA to help us understand the latest Thai wiring regulations. They're in both Thai & English languages, so are easy to understand. I hope this helps. 3 เฟส 19-10-59-.pdf Link to comment Share on other sites More sharing options...

There are other documents floating around that actually switch between Euro and US cable colors as you jump pages. The same applies to current carrying capacity of cables. Its almost as though they are cutting and pasting other countries regulations and losing the plot in translation. PEA currently operate the flexi rule system.

SteveB2 Posted September 20, 2017 Share Posted September 20, 2017 Just in case you missed it... The bulk of the PEA information is in the attached file ---> 3 เฟส 19-10-59-.pdf <--- There have been major changes to the Thai wiring code over the last few years - our own building that was built to code 5 years ago failed PEA audit when we requested the supply be connected. Much work had to be done to bring it up to the latest code requiring 5 audit visits to sort out before eventually being approved Link to comment Share on other sites More sharing options...

My point was, the document posted here is one of many variations floating around the PEA at various locations. The whole system is a joke. Link to comment Share on other sites More sharing options...

Sadly I have to agree, it's pretty obvious that, despite attempts to regularise by requiring electricians to be registered / licenced, nothing is really changing (or if it is it's a very slow process). Individual offices (just like Immigration) make up their own rules meaning that it's imperative to visit your PEA office to find out what they want particularly regarding the incoming cable size and main breaker. Anything inside that's wired with even a nodding recognition of the requirements in BS7671 or AS3000 will likely be fine. And once you have your permanent meter no further inspections are required.

Although a licence is technically required most don't have one. The only test or inspection is when getting a new permanent supply. Link to comment Share on other sites More sharing options...
jeab1980 Posted October 8, 2017 Share Posted October 8, 2017 Its stated a few times here there was an inspection prior to pea putting in supply? We requested a meter be installed aftervwe got the house number and blue book. The only thing what happened was a pea van drove up looked where the house was looked for nearest electric post. Came over said no problems and came back an hour later with another van in tow they put the supply to the meter on post got us to sign the form and left. We conected house and shop to meter.

We didn't even get a PEA vehicle for our inspection. I did a lot of research & was beyond prepared for it. Ornery old dude who obviously hated his job pulled up on an old Honda Wave, he didn't want to see squat. Asked if I had a ground & lightning rod, signed off & left. He was pissed because he had to look at 5 houses that day. Link to comment Share on other sites More sharing options...

Our "inspection" was certainly somewhat, er, rudimentary. Mostly consisting of the inspector gassing with Wifey, he did look inside the distribution board and said I couldn't use the 63A incoming breaker that was installed on our 15/45 meter, I don't recall if he actually came back and checked we had replaced it (probably not). If you are paying the permanent rate of about 4 Baht per unit you're fine. Link to comment Share on other sites More sharing options...
