Does my CU set up comply with Thai regulation?
Crossy replied to jim234's topic in The Electrical Forum
Thailand is 3-phase, 4-wire (3 phases + neutral). Single-phase supplies take from one phase and the neutral. So, if you have a 3-phase supply to your home you can treat it as if it was 3 single-phase supplies. The "400V" (actually 380V) is phase-to-phase and only relevant if you have 3-phase appliances. It's very likely that your 30/100 isn't really capable of 100A, at least not whilst maintaining the 220V+-10% that it supposed to. Our 15/45 village supply drops about 25V at 50A so just about OK, but it doesn't take much load elsewhere in the village to pull it way down, the under-voltage trip opens at 165V which it does rather more often than I'd really like. If you are building a new place, I would wire it as if you are having 3-phase then use a "single-phase kit" on the incomer if you start off with a single-phase supply (as your construction supply will be). -

I'm just imagining the furore back home if they did something like this. Blackface, cultural appropriation, the woke brigade would be having kittens! I think I saw the chap on some Robertsons Jam long ago ...

By the way kosher salt is not necessarily kosher, it actually gets its name from its use the process of koshering (or kashering) which is the process of removing all blood from the meat to make it kosher.

John visited his 90-year-old grandpa who lived way out in the country. On the first morning of the visit, John’s grandpa prepared a breakfast of bacon and eggs. John noticed a film-like substance on his plate, and asked, “Are these plates clean?” His grandpa replied, “They’re as clean as cold water can get them. Just go ahead and finish your meal.” For lunch, Grandpa made hamburgers. Again, John was concerned about the plates, as his appeared to have specks of dried egg on it. “Are you sure these plates are clean?” he asked. Without looking up, Grandpa said, “I told you before, those dishes are as clean as cold water can get them!” Later, as John was leaving, his grandpa’s new dog started to growl and wouldn’t let him pass. John said, “Grandpa, your dog won’t let me get by!” Grandpa yelled to the dog, “Cold Water, go lie down!”

Three expectant fathers – one English, one Welsh, one Pakistani – are tensely waiting outside a hospital delivery room. The doctor comes out and says, “I’ve got good news and bad news. The good news is that all your wives have been delivered of healthy baby boys. The bad news is we’ve somehow managed to muddle them up, so we don’t know whose baby is whose.” “I have an idea,” says the Englishman. “What if we go in one by one to see if we can spot any physical characteristics that will help us determine which baby is which?” “Well, if it avoids a lawsuit…” says the doctor. So, the Englishman goes in and comes out 10 seconds later with what is obviously the Pakistani baby. “This one’s mine,” he says. “Excuse me,” says the Pakistani father, “I couldn’t help noticing that the baby you have chosen appears to share some physical characteristics with me.” “I know,” says the Englishman, “but one of those b'stards in there is Welsh, and I’m taking no chances.”

Large motors and powertools on hybrid inverter
Crossy replied to Pink7's topic in Alternative/Renewable Energy Forum
Check the manual of your inverter, many are actually grid-sync and will top up solar with the grid whilst still using what solar is available. Others will simply go into bypass mode. Of course, both these modes have a limit. -

@bluejets did you mean single-width?? Single-width 2-pole (rather than solid neutral) RCBOs are certainly available, we use them in the BTS distribution boards, but they are not particularly common or cheap. -

Since I do not wish to be "targeted" I hope one can opt out of this system.- 38 replies
