240, single phase for houses
208 3 phase for comerical property, can be single phase.
480 volt for industrial property or 660 volts,
all 60 Hz
USA calls it single phase but there is actually 2 hot leads coming into the house with a natural and a ground.
- It is actually two 120 volt 'hots' which are 180° out of phase from each other. Voltage between either of these and ground will be 120 V. Voltage between the two hots is 240 volts. It is single phase because it is pulled off one of the phases from 3-phase, then a center tapped transformer gives the two 'opposite phases' (ground/neutral is off the center tap)
In Vietnam we have 440 volts, 3 phase, 50 Hz on the poles.
They bring in one hot wire and one ground. I call this single phase,
It equals 220 volts in your house.
What else can I help you with?
How do you wire three phase into the mains?
In the UK, the term, 'mains', refers to the supply voltage provided by the distribution system. In most residential properties, the mains' supply is single phase (there are exceptions: some European countries have three-phase supplies), in which case you cannot 'wire' a three-phase load such as an induction motor into the mains.
Why do some appliances have step down transformers built into them?
Because the appliances operate at voltages that are lower than the mains (supply) voltage.
Advantage of low voltage over mains voltage?
Less likelihood of electrocotion.
One possible risk caused by mains voltages?
-- proliferation of electrical and electronic devices in the home, leading to a surprising and shocking bill at the end of the month; -- excessive current flowing in an inadequately sized conductor, leading to overheating and possible fire; -- grave mortal danger to a human person, caused by placing his body in-circuit between the mains supply and a grounded point. Note that none of these risks is "caused by" the mains voltage. Any risk is due to careless and inattentive handling of the mains supply by people responsible for its proper use. In this respect, mains voltage is no more risky than a car, a bottle of sleep aid tablets, a pistol, or a discarded banana peel.
Why can a shock from mains electricity kill you?
it can stop your heart Certainly UK mains voltage,,240 V ac is enough to kill an average person

What is voltage required for desktop?
Desktop computers all come with a power supply that changes the mains voltage in your country's electricity supply to that needed inside the PC. Thus the Voltage used by your PC is the mains voltage in the country where the PC was sold.
What is service mains in power transmission system?
A 'service mains' is not associated with an electricity 'transmission' system, but with a low-voltage 'distribution' system. The service mains is the name given to the cable that connects a building to the low-voltage mains supply.
What must you match when purchasing a power supply?
The equipments power requirements, and the mains voltage. The output of the power supply must be able to deliver the correct voltage to the equipment, at the appropriate wattage. Additionally, it should be capable of operating on the supplied mains voltage and wattage.
Will your US laptop work in the UK?
Not without a suitable mains adapter to charge the battery. The UK mains voltage is 230 Volts - the US mains runs at just 110 colts.

In the UK the mains voltage is 240 volts
How do you wire three phase into the mains?
In the UK, the term, 'mains', refers to the supply voltage provided by the distribution system. In most residential properties, the mains' supply is single phase (there are exceptions: some European countries have three-phase supplies), in which case you cannot 'wire' a three-phase load such as an induction motor into the mains.
What is the NEC minimum fused rating for a residence?
This will depend on your country and of course on your mains voltage. In New Zealand, 230v AC, 60 Amp would be a common mains fuse for a residence.
What is the power voltage in Indonesia?
