Not thailand, but Asia. I couldn't figure out why our electricity would go out seemingly at random. I eventually found out that two houses had broken into the breaker box on the pole and connected with cable you would use for a lamp. It would thermal all the breakers in that box.
Often there is a local box that then goes to 12-16 houses, there is one main for that. Once run to your house you can do what you want, no one is inspecting you.
The electric company came out because of complaints and saw what hapened, they just cut the cables and relocked the box
