Yes. After I had electrical wiring burn out late February the thai sparky came and cut the burnt out wiring out and twisted together with tape. (TIT). Power use escalated several months. AC compressor was rooted. Owner replaced. Bill went from 2200 down to 1100 this period. I ran daily and weekly checks to gauge wtf was happening. Now I put the air conditioning on whenever I want. Lol. But it's pretty easy to buy a cheap clamp test meter if the original poster thinks Power may be syphoned and test the draw. When I turn the bathroom light on the firestick and TV goes off.. Obviously not a balanced circuit . Older rental. And this is Thailand.
. I know it usually draws comments the agent or immigration direct method. But there's a lot of people who do it. I go through Buriram. Which goes through Kohn kaen. All official stamps. Receipts. Jomtien immigration and Hua hin does it also. Plus others. I'm not married to my partner. So it would be 65k transfer monthly, or 800,000 maintained balance in a thai account . Horses for courses as they say...
