Here is the installation guide for domestic electrical systems that I was given by my local electricity company. It’s (naturally) in Thai, but the tables and graphics are fairly self-explanatory. I found it helpful to ‘look at together’ with our electrician, who would otherwise have continued to doubt the need for things like heavier cabling to the kitchen outlets and proper ‘crown’ cable joins.

The contents are broadly as follows:

pages

1-5 Connecting to the supply; overview of system; consumer unit; ground rod

6 -12 Cable types and diameters

13- 20 Laying and connecting cables

21-30 The grounding system

31- 38 Circuit breakers and switches

39-43 Welding and splicing techniques

Thanks for that anatta, I don't think this has been uploaded before so a good find.

Anyone fancy doing a basic translation??

And, just curious, was that a local thing or perhaps Thailand coming out with a national code?

Maybe you could pin this or put it in your electric post Crossy. I wanted it some time ago and was unable to find it.

If you look at the first page it says 2546, we are now going into the year 2555/2012.
