All you have to do is install a Y fitting on both hot and cold shut off valves inside the cabinet. The other alternative is to T into the water supply and run new pipes for the other sink.
Answer for USA, Canada and countries running a 60 Hz supply service.The difference between a double pole switch and a single pole switch is the use of the switch in the installation or equipment. A double pole switch is used when the voltage from two circuits has to be broken. An example of this is a 240 volt supply. A single pole switch is used where there is only a single supply voltage that has to be broken.
A single handle uses the same 3 holes as the double handle
Yes. The double pole breaker can be removed and replaced with two single pole breakers. The double pole breakers are only used for 240 volt supply loads.
A line thermostat on a 240 volt heater must open both of the supply lines that feed the heater. This is where the double pole thermostat is used. On 120 volt heaters only one hot line needs to be opened to shut the supply off from the source therefore a single pole thermostat is used.
Question is unclear. A double sink can use one drain, you would anchor the base to the wall the same as a single sink and the vanity is on top or in front of the drywall. If you are replacing a single sink with a double, the supply and drain could be in the vanity, you would not have to open up the wall.
Provided they fit and do not overlap, and you have the proper power connections and power supply, yes.
Bcoz in single phase if supply is interrupt or any trouble there is no power .but in 3 phase if 1phase supply gone we can manage it by other 2 phases
any power supply with at least 175 watts

Double pole Single Throw switches are sometimes called DPST switches. Assuming the circuit is single phase two wire system, DPST - are used to isolate the ciruit. Isoloation occurs on both terminals hence it is called double pole. This isolation occurs at only one end in the circuit, hence it is called single throw.
