Hmmm, the plot thickens. Is it on a regular switch or some kind of electronic switch?? Could even be an iffy connection.

I've had issues with those quick connectors in the past, can you try just twisting the wires or use a screw connectors.

OK so we now know the lamps are AC/DC, would have been nice to know earlier, but whatever. So your AC "transformer" won't blow it up, but it's flickering. It could still be that you are under-loading the transformer (although it doesn't state a minimum load), can you try hooking up half a dozen or so of your 4W lamps to it in parallel. The DC unit that I posted earlier would still work fine ???? You're not using a lamp dimmer are you?? I also notice that this appears to be a "smart" RGB lamp, not sure if that matters.

Here's your problem:- And again this unit appears to be intended to drive halogen lamps up to 50W. You need a driver/power supply with a constant voltage output of 12V DC, nothing more, nothing less.

Can you give us some information on this driver please, a photo and / or spec. would be great.

Are you intending to go grid-tie with just hot water to store excess (and no grid export), or would you add batteries to make a hybrid system for energy when the sun is sleeping. Contractor or DIY install?

Yeah, it's a lot more scary than it seems to the lay-person, a warm floor and few tingles could easily have turned into a full blown zap! We could easily have been reading about the "mystery deaths" of a farang and his family ???? And even if the Safe-T-Cut was functional it would have made no difference!! This sort of thing is one reason I have a 2-pole isolator on the incoming tails, before any N-E link etc. Probably not legal to the regs, but ...

It's not set to "Bypass" or "Direct" is it??

Definitely, I had never come across an TNC-S that had L-N reversed and the sparks hadn't noticed. Until today!

Better if you use a meter to a known earth (my infamous big screwdriver in the lawn), but the neon does a quick check.

As a final check, verify that there's no voltage between the regulator "neutral" terminals (they are usually connected together internally) and the "neutral" in the distribution box (or one of the screws on the DB case). The regulator will work OK if it's incorrect polarity but it's best if it's actually right.

If it was PEA at fault you could ask for a refund based upon your observation of the meter. Or maybe file that in the "too hard" box

Do you have any test gear (cheap multimeter)? I'm really loathe to suggest anything but you could try measuring the voltage of both your incoming lines (L and N) to a real earth (not your rods, a big screwdriver in the lawn). That would allow you to determine where the reversal actually is. EDIT I don't know what your meter-constant is but ours is 400 revs/kWh. At about 2 revs per minute that's going to be 200 minutes per kWh or around 7kWh per day that's been warming up your floor (something like 900 Baht per month on your bill).

Where is your N-E link in relation to the regulator? Is there an isolator / breaker in front of the regulator (between the regulator and meter)? Since you have a 30kVA unit I'm assuming it feeds the whole house. You really, really need someone who knows what they are doing. But I suspect whoever determined that the connections were reversed and "fixed" it was mistaken and screwed things up ???? I still strongly suggest that you get PEA out, even if it's only to confirm that the supply entering your home is the correct polarity. Again, this is a potentially lethal situation which could lead to any "earthed" metalwork becoming live to mains voltage with no way to isolate and no fuse between it and the village transformer.

As above, this statement immediately says "L-N reverse" to me. There could be another reason for the hot rod, but neither of them is a DIY fix anyway. Touch nothing!!! Call your local PEA emergency number and get them out now! Meanwhile turn off the main breaker. It won't make any difference to the hazard but will allow you to check if your meter is still clocking energy consumption and give you something else to show Mr PEA when he turns up. Please let us know what happens.

OK let's clear this up. The unit in our OP is an "electronic transformer" intended to drive halogen lamps. It's output is 12V AC. It has a MINIMUM load of 20W. Our OP has 12V DC 4W LEDS. Just about everything about the transformer is wrong for those LEDs, with only a 4W load it may not even start up, if it does there's a strong possibility it will fry the LEDs. This is one of many suitable drivers on Lazada https://www.lazada.co.th/products/led-driver-adapter-12v-15a-18w-transformer-power-supply-for-led-strip-i3194981777-s11933177910.html Note:- This is an 18W power supply, so it will happily drive up to 4 of our 4W LEDs connected in parallel.

Don't worry, another fault is waiting to manifest itself when the damp soaks in

Not before 15:30 except when it's a party.

Something like this (get the one with the clip-on CT if you don't want to pull and wires) would do the trick. https://www.lazada.co.th/products/100-original-diymore-ac-50-300v-0-100a-power-energy-meter-voltmeter-ammeter-kwh-digital-ac-electric-monitor-panel-meter-with-reset-function-i3125367961-s11626606839.html? Clip the CT (current transformer) over the live supply to the unit you want to monitor, for an A/C it would be easiest to do it where the wire exits the breaker.

Maybe not new, but there are some I've not seen before :- The Darwin's Are Out. Yes, it's that magical time of year again when the Darwin Awards are bestowed, honoring the least evolved among us. Here Is The Glorious Winner: 1. When his .38 caliber revolver failed to fire at his intended victim during a hold-up in Long Beach, California would-be robber James Elliot did something that can only inspire wonder. He peered down the barrel and tried the trigger again. This time it worked. And now, the Honorable Mentions: 2. The chef at a hotel in Switzerland lost a finger in a meat cutting machine and after a little shopping around, submitted a claim to his insurance company. The company expecting negligence sent out one of its men to have a look for himself. He tried the machine and he also lost a finger. The chef's claim was approved. 3. A man who shoveled snow for an hour to clear a space for his car during a blizzard in Chicago returned with his vehicle to find a woman had taken the space. Understandably, he shot her. 4. After stopping for drinks at an illegal bar, a Zimbabwean bus driver found that the 20 mental patients he was supposed to be transporting from Harare to Bulawayo had escaped. Not wanting to admit his incompetence, the driver went to a nearby bus stop and offered everyone waiting there a free ride. He then delivered the passengers to the mental hospital, telling the staff that the patients were very excitable and prone to bizarre fantasies. The deception wasn't discovered for 3 days. 5. An American teenager was in the hospital recovering from serious head wounds received from an oncoming train. When asked how he received the injuries, the lad told police that he was simply trying to see how close he could get his head to a moving train before he was hit. 6.. A man walked into a Louisiana Circle-K, put a $20 bill on the counter, and asked for change. When the clerk opened the cash drawer, the man pulled a gun and asked for all the cash in the register, which the clerk promptly provided. The man took the cash from the clerk and fled, leaving the $20 bill on the counter. The total amount of cash he got from the drawer... $15. [If someone points a gun at you and gives you money, is a crime committed?] 7. Seems an Arkansas guy wanted some beer pretty badly. He decided that he'd just throw a cinder block through a liquor store window, grab some booze, and run. So he lifted the cinder block and heaved it over his head at the window. The cinder block bounced back and hit the would-be thief on the head, knocking him unconscious. The liquor store window was made of Plexiglas. The whole event was caught on videotape. 8. As a female shopper exited a New York convenience store, a man grabbed her purse and ran. The clerk called 911 immediately, and the woman was able to give them a detailed description of the snatcher. Within minutes, the police apprehended the snatcher. They put him in the car and drove back to the store. The thief was then taken out of the car and told to stand there for a positive ID. To which he replied, "Yes, officer, that's her. That's the lady I stole the purse from." 9. The Ann Arbor News crime column reported that a man walked into a Burger King in Ypsilanti, Michigan at 5 A.M., flashed a gun, and demanded cash. The clerk turned him down because he said he couldn't open the cash register without a food order. When the man ordered onion rings, the clerk said they weren't available for breakfast... The frustrated gunman walked away. [*A 5-STAR STUPIDITY AWARD WINNER] 10. When a man attempted to siphon gasoline from a motor home parked on a Seattle street by sucking on a hose, he got much more than he bargained for. Police arrived at the scene to find a very sick man curled up next to a motor home near spilled sewage. A police spokesman said that the man admitted to trying to steal gasoline, but he plugged his siphon hose into the motor home's sewage tank by mistake. The owner of the vehicle declined to press charges saying that it was the best laugh he'd ever had and the perpetrator had been punished enough!

Or Yakult.

Yup, Mumbai is still BOM (Bombay).

Or get rid of those pet penguins ???????????????????????????? ???? How big is the room it serves? Do get some sort of energy monitor on the beast, you may be pleasantly surprised.
