Hot wire can be either black, or red in most cases. However in certain situations (such as 3 or 4 way switches) the white, or neutral wire may be "hot". Such cases should always be taped or colored black, but sometimes are not. Best to test with a good circuit tester, they will tell you voltage, as well as polarity!
For wiring in the USA the Neutral conductor is required to be white or gray by the National Electrical Code.
No !
A 240-volt circuit typically consists of two hot wires and a ground wire, with no neutral wire. The hot wires each carry 120 volts, while the ground wire is used for safety purposes. In a 240-volt circuit, the hot wires complete a loop by connecting to a load or device that requires the higher voltage to operate.
Answer for USA, Canada and countries running a 60 Hz supply service.240 volt two wire circuits loads do not need a neutral to operate. A three wire 240 volt circuit that needs a neutral, will have a neutral the same size as the current carrying conductors. In this case a #10.
Any ground wire has to be connected to an independent ground wire that returns directly to the distribution panel and not to the neutral of the circuit.

In residential wiring the white wire is neutral on the 120 volt circuits. On a 3way circuit the red is the traveler and the white is neutral. On a 240 volt 3 wire connection the white & black are hot. On a 240 volt 4 wire connection the black and red are hot and the white is neutral.
Because the white wire on a 120 volt circuit is the neutral wire that is connected to the silver screw on outlets and switches. It is connected to the neutral bar in the service panel.
In the US of A, it's supposed to be black.
In North America the cable colour coding is Red and Black, usually used for the current carrying conductors. The third wire is White and it is used as the neutral on a three wire electrical circuit.

yes <<>> No, the ground wire is never to be used as a neutral. In this case if you need a 120 volt circuit from the 220 volt circuit a three wire cable (3C #14) must be installed.
The recommended wire size for a 220 volt circuit according to the 220 volt wire size chart is typically 10 gauge wire for a circuit with a maximum of 30 amps.
In an electrical circuit, the white wire is typically designated as the neutral wire.
