You will probably need a smoothing capacitor on the output so the valve doesn't buzz, say 1000uF 50V. Also, that bridge is waaaaaay over-sized, look at something rated around 50V 1A ????

Don't panic (yet), it's only money brought into Thailand that's taxable and you may be protected by the Thai-US double taxation agreement.

Wife checked her husband's phone and found these names: Super Woman My Love Woman of my dreams Princess Sweetheart Honey bunny She got angry and called the first number and her hubby's mom answered. Then she called the second number and her hubby's elder sister answered. When she dialed the third number her own phone rang. She called the next one, it was their daughter's phone. She called the next one and it was her own mother and then she called the last one it was hubby's junior sister's number. She cried until her eyes got swollen because she had doubted her 'innocent' husband, so she gave him her whole month's salary to make up for it. Husband took the money and bought this for his girlfriend whose name was saved as #Mechanic ????‍????????‍????????‍????????‍????????‍????????‍????

I do have this t-shirt although it was my employer who installed the bolt! I would have installed a proper 32A Commando socket on sensible wiring but, small company, no money, you know the story.

Generally, PEA is 220V phase-neutral, MEA is 230V phase-neutral. Of course, locally all bets are off due to compensating for overloaded transformers and transmission lines. In reality it matters little as all your kit should be happy with either voltage +- >10%.

NO! Because there is already 220V between any one of the phases and the neutral. If you look at the poles outside your house you will see 4 wires, three of them are the phases and one (usually the top one) is the neutral. If you trace the wires that go to your house (via the meter) you will see that they are connected to one of the phases and the neutral. No transformers or anything else needed, it's just the way 3-phase 4-wire works. Dead handy. 3-phase appliances just connect to the three phases without using the neutral, unless they have 220V control gear. What sort of power consumption would the lift be? Plenty of 3-phase off grid inverters (either single unit or three single-phase units running together). EDIT 2 A quick Google puts the lift motor at around 2HP, that's well within the capabilities of a single-phase installation, check with your chosen lift supplier to see if they offer a single-phase version. EDIT This diagram may help, note that it's for 230V phase-neutral but you should get the idea.

Phase to Neutral 220V your normal single-phase supply. Phase to Phase 380V which is what 3-phase appliances see. The apparent "weirdness" is due to the 120o phase angle between the phases, I'm not going to go into 3-phase theory here, but Mr Google or Wiki can be a lot of help in understanding.

Definitely in the "not at all worried" window. For now, at least.

You can tell a lot about a nation, by visiting the zoo.

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).

Fixed it for you ????
