208/120 is typical for the US, so these are the colors for the US: A phase: black -------------------In Canada; A phase - Red B phase: red-------------------------------------B phase - Black C phase: blue -----------------------------------C phase - Blue neutral: white -----------------------------------neutral: white ground: green or green with yellow stripe
Black,red,white,blue

In Canada the colour coding is Red, Black, Blue, and the grounded star point identified with a White conductor.
Black is hot, white is neutral and bare wire is ground. Neutral and ground are bonded together at the main panel.
In Canada, Red, Black and Blue for lines L1, L2 and L3. White for Neutral.
In the US, Black, Red and Blue for lines L1, L2 and L3. White for Neutral.
Telling the colour of wires has nothing to do with using a volt meter. Phase wire colours can be any colour except green and white. Usual 3 phase colours are red, black, blue. Single phase colours are usually red and black. Neutrals are always white and ground wires are always green or bare.
600 volts between any two wires. The phase has nothing to do with voltages, only current relationship.
The National Electrical Code requires that the neutral wire is to be designated as the "identified" conductor. Method differ, but look for ridges, lines, or writing on one of the wires.
electrical wires are selected to satisfy with the desired conditions and supply.
If single phase - 2 wire service > two wires If single phase - 3 wire service > three wires If three phase - 3 wire service > three wires If three phase - 4 wire service > four wires US residential service is usually single phase 3 wire service: Two hots and neutral.

it is represented by color coded wires
A single-phase cable will have a line and a neutral conductor and, possibly, but not necessarily, an earth (ground) conductor. A high-voltage three-phase cable will have three line conductors. A low-voltage three-phase cable is likely to have three line conductors and a neutral conductor.
poles are the wires and where they are connected
Most electrical equipment are either designed to work on Single phase (two wires) or Three Phase (three or four wires). Two phase equipment are non existent today. A single phase heater will require a single phase thermostat while a three phase heater will require a three phase thermostat.
Three phase electricity allows power to be transmitted more efficiently because three live wires do the same job as three pairs of wires (6 wires) of the same size to transmit the same amount of power in single-phase. So 3-phase needs half the amount of wire.That is because with 3-phase the AC in the wires is timed so that the three wires act as each other's return wire, you don't need return wires.That is important for transmitting large amounts of power.CommentAlthough a three-phase system is more economical than a corresponding single-phase system, the amount of copper saved is around 75% -not 50%.
Because a three-phase system needs half the amount of wire to transmit power compared to three single-phase systems. With a balanced three-phase system the three live wires are phased so that the sum of the currents is always zero, which means that if the three neutral wires are combined, the current in the neutral is zero. Therefore the original three neutral wires can be removed, leaving only the three live wires. In practice a neutral wire is still included in three-phase four-wire systems when the load is potentially unbalanced, as for example in neighbouring houses which use different phases of a three-phase system for their individual single-phase supplies.
