Your TOU when it comes will likely be an electronic meter, they are all 5/100 so no problem upping your incomer.

Consider which circuits really need an RCBO. Don't worry: - Inside lights Inside outlets that aren't likely to feed stuff used outside (bedrooms etc.) Aircons Do worry: - Outside lights Outside outlets and inside outlets that might get garden tools etc. plugged in Outlets in wet rooms and the kitchen (but consider having an "unprotected" circuit for the fridge / freezer) Water heaters The Shed Pool stuff

1) For preference I would use the Bticino ones, around the same price as Schneider. These are the units guaranteed to fit and will maintain any type-approvals. Nano and Chang are both low-cost alternatives, I've not used their plug-in units but the DIN ones are fine. Schneider / Square-D are, of course, a well-known, decent quality brand. 2) Do you have your permanent supply meter? If not don't replace your incomer until the inspector has been and gone. What size meter do you have? I wouldn't go over 65A on a 15/45, it's not going to explode but the accuracy falls off at high current, bet it won't read low! Is your incoming cable copper or aluminium? 16mm2 copper should be good for 90A in free air, aluminium 70A. As always, Up2U.

Ditto. Mildly annoying but if that's what they want what can we do?

I must admit I've often wondered just what they are looking for, but definite respect for at least one now ????

The general Thai guesstimate for A/C sizing is 600-700 BTU per m2. It's horribly basic and tends to over-size but with modern inverter A/C over-sizing isn't much of an issue. Your 16m2 bedroom would come out at 9,600 - 11,200 BTU, I'd look at the smaller end of that with a well-insulated room. The 32 m2 lounge would be 19,200 - 22,400 BTU, again well insulated would tend towards the lower end. Like many things, you can calculate to the nth digit and then have to pick from a limited range of available values. Definitely go for inverter units for energy savings.

Some units will refuse to heat if no earth, but I've not seen one here. It's possible that your national regs. require this function.

No, that will be fine, easier to get into your pipe ???? Rating is the same as the solid.

Sounds a bit odd, if it's a government road the PEA should have an automatic easement to put up poles. But if you need to place poles on a non-government road you will need to obtain an easement from the property owners. I expect PEA will want to put your meter at the main poles, so the second will apply ???? For clarity could you include a sketch map or Google maps snap of the location (remove any identifying data for privacy). Maybe a little "lubrication" at PEA would smooth the flow

I'll bet it has none, just a simple capacitor dropper, at these power levels they work well. Of course, it means that the internal electronics is potentially at mains voltage, but with no interface to the outside world it matters not. Note that this unit may be rather cleverer as it's dual AC/DC power supply (there are some dead clever PSU chips around these days), but I bet it's still not actually isolated.

If find Bard much more useful. Probably the only sense to come out of a @GammaGlobulin thread ????

At 04.30! Frosties!! I need the sugar hit to prepare for a nice stressy morning of moaning at contractors. Real full-fat milk. And, as a Brit, tea of course (no milk or sugar). Lunch will be in the office canteen, rice and two sides - 35Baht. Dinner will be whatever Madam has prepared and a couple of cans.

Who is the pretty???

Yeah, at 17A they would be OK (but not recommended) particularly as most bedroom kit is low power. https://hitachi-magic-wand-massagers.co.uk/pages/magic-wand-massager Now someone will be along who runs a welder in the bedroom. There's no accounting for those kinks!!

Yeah, if it was >20m I'd be thinking a bit. But for an intermittent load like a shower ... Unless, you have teens!!!

No, if in conduit the conduit is the "double". Just use regular 6mm2 THW and you're good to go. EDIT For normal people 4mm2 THW would be OK for a short run. If you have teenagers go with the 6mm2???? Do ensure that you have a good earth connection to the heater!!
