No, no, no, you all have it wrong!!!

Taking the UK as an example, it has to be a scotch-egg.

Peek Traffic (a UK company) actually installed a system in 1994. https://www.academia.edu/11604715/ASSESSMENT_OF_AREA_TRAFFIC_CONTROL_SYSTEM_IN_BANGKOK_BY_THE_MICROSCOPIC_SIMULATION_MODEL

Anecdote. Back in the 1990’s we were working in Ankara, Turkey. At the time hailing a cab wasn’t permitted, you had to call. Anyway, one lunchtime we were sitting outside a nice little cafe with a coffee when a couple of locals wandered up with a reel of cable and a bell push. They proceded to screw the bell push to a tree and string the cable from assorted branches. Odd we thought. Some time later we were outside another lunch cafe when a lady with shopping came along, located a similar bell push (on a light pole this time) and pushed it. A few seconds later a taxi screeched round the corner and picked her up. The 1990s Turkish version of Uber.

Pretty much, the fixed fee isn't much so it usually vanishes in the guesstimate. Don't sweat the small stuff and enjoy the Land of Smiles!

It's been tried at least twice, the BiB decided they could do a better job of creating jams and disabled it within a few days.

Not exactly ...

"In the town where I was born ..." now it's ruddy well stuck in my brain for the rest of the day ...

The problem with "smart" anything in LoS is that it pretty soon becomes "dumb" due to poor installation followed by lack of maintenance / repair ???? Anyone remember the "smart taxi stops" (scrapped in 2019 without ever going fully live)?

I think that's the latest, the Ft (fuel tariff) is what they use to adjust the rate rather than modify the base tariff. It's all detailed on your bill. The "4.5 Baht a unit" is a guesstimate based upon the "normal" usage and since most of us use over 400 units per month it works out reasonably well, certainly well enough to catch gross errors.

Assuming it's big enough for your space it's likely no better or worse than the other big brand units. We just installed a Sharp inverter in our bedroom to replace our 10 year old non-inverter Samsung which was leaking like a sieve. It works well enough and the nergy consumption seems to be reduced.

I'd visit your local hospital OPD and explain the symptoms, shouldn't cost the earth.

If your guesstimate comes out as less than MEA are asking for then fight it. Otherwise just cough up.

It's very difficult to compare other people's usage with what yours "should be". For example, we use around 35kWh per day, inverter A/C only at night and we don't have a pet penguin (set to 26C). Our biggest single power user - Madam's ruddy koi pond ???? Luckily we have a big chunk of solar so we are not paying PEA for 80% of our usage.

I assume you have a new meter now. Can you guesstimate what a month would be from what it reads now vs what it read when installed? At least then you would have something to go in to bat with (assuming your guesstimate is less than they are asking of course). Is your bill from MEA/PEA or "someone else"??

I'd go with a 20A MCB, ChinT are a mid range Chinese maker that won't break the bank ????

No! In the baby box you have the arrestor and a 1-pole breaker (MCB) in the live to protect it. 3 wires from the baby box, E goes to the earth bar in your main unit, N goes to the N bar, L goes to the outgoing live terminal of your existing main breaker. Probably the easiest place to pick up the live is from the leftmost terminal on the live bus-bar, a bit of 6mm2 should fit in the same terminal with the bus bar. Nothing needs to change in your existing box so that's nice and easy. You can put the baby CU in a convenient place, but keep the wires as short as possible.

There are gazillions on Lazada, a 4 unit one would fit one of the 100kA arrestors and a single pole MCB (you just need to open the live). Something like this https://www.lazada.co.th/products/4-consumer-unit-4-channel-2-4-i2676671412-s9640187556.html Ours came from Mega-Home as I'm the instant gratification type, this one is on our solar inverter hence the 2-pole MCB and smaller arrestors. Or you could get a bigger one and move your incomer and RCBO into it before feeding to your existing box. Many, many ways to go about this job ????

Yes ^^^, services, flooding issues and most important access rights. Who owns the access to the main road, if it's across private land is there an official easement in place permitting permanent access? Gentleman's agreements have an annoying habbit of getting screwed up by a less-than-gentleman who sees the $$$ ????

How are the green cells performing??

Putting two A/C units on one breaker isn't ideal but shouldn't be an issue. Ideally you incoming surge suppression needs to be connected as close to the incoming supply as possible, so at the left end of your CU. Some shuffling would be needed. Also, a decent 80 or 100kA suppressor is more than one unit wide so it still really needs to live in a separate box, not difficult to arrange. If I was doing it, I'd take the surge suppression directly off the switched side of the main breaker. We have a unit similar to this https://www.lazada.co.th/products/b100-2p-60ka-100ka-385v-ac-1pn-spd-i3487044637-s12946508088.html it's 3 CU positions wide, add to that it's MCB. A "garage" CU box would house it all nicely.

Who is asking for the $$$? PEA/MEA or someone else? I find it "interesting" that 8 meters were "damaged". Does your bill look something like this? (could be orange instead of purple)

Nothing to stop you adding a small DIN box to contain your surge arrestor and it's MCB. Or you could rationalise your circuits to free up an MCB which could then feed your external box. That little AVR looks OK, as you say it's a bit light on surge suppression but give it a nice big beast in the CU and you're gold.
