It depends in which country you live, as the colours depend upon national or international standards. In the UK, for example, the colours were red, yellow, and blue. These days, in order to integrate with EU requirements, those colours are being replaced with brown, black and grey.
In Canada the phase colours are Red, Black and Blue.
In the US the phase color coding is Black, Red and Blue for 208 volts and Brown, Orange and Yellow for 480 volts.
See related links below.
In the US: A phase - brown B phase - orange C phase - yellow neutral - gray ground - green or green with a yellow stripe. Note that the ground color is the only one mandated by code. The others are simply industry standard usage.
In the US and Canada (and probably elsewhere) neutral is always white or grey. In the EU, neutral is always blue. It does not matter if you are talking one phase, split phase, or three phase. Legacy wiring in the UK, prior to 2006, has neutral as black.
In accordance with EU harmonisation requirements, the colours for three-phase line conductors are brown, black, and grey, with a blue neutral. Utility companies who have yet to adopt these colours use red, yellow, and blue for the line conductors.
green is ground (THE LAW)
white is neutral (THE LAW)
any other colors are permitted for the phase conductors
standard practice uses brown/black/orange 480/277
120/208
black/ red /blue
machine control voltage JIC convention
220 or 480 black
120v red
24v blue
white neutral(still THE LAW)
green ground
DIN Europe have a bit different grounding (earthing) convention
green with yellow traces is what we call grounding electrode conductor
usa is usually solid bare copper
the green is separate to the same common but never looped or chained
( ground loops are a problem with low voltage electronics )
AnswerAlthough 480 V isn't a standard voltage in Europe, the colours used to identify the line, neutral, and earth conductors are as follows:
The color code for 3phase 240 volts is PHASE A- BLACK PHASE B- RED PHASE C- BLUE
The UK standard is brown=live, blue=neutral, green/yellow stripes=earth.
red, yellow & blue
Black red blue

The three colours used in the UK are: blue (live), brown (neutral), yellow and green stripes (earth). The standard UK domestic voltage is 240 volts.
At 120 Volts you would draw about 42 amps. At 240 Volts it would be about 21 amps. For 120 Volts you would need 6 AWG and for 240 Volts you would need 10 AWG.

In Europe 240 volts is standard, so no a 115 volt motor will not work. In USA 120 volts is standard, so if your sub-panel has 120 volts, (check with voltage meter) then yes. Read carefully, To get 240 volts in a sub-panel in USA the electric company brings two (2) wires, each wire has 120 volts, 120 + 120 = 240. One of those 120 volts will run your motor. Look for the wires from the electric company and check them with your voltage meter. If this is a commercial application you will need to call an electrical contractor, power companies for commercial applications do not follow the above.
The three colours used in the UK are: blue (live), brown (neutral), yellow and green stripes (earth). The standard UK domestic voltage is 240 volts.
Unlikely- European countries run on 240 volts which is about double the US standard.
Standard wiring for 220 volts which is also referred to as 240 volts, commonly has four wires. One is red, one is black, one is white and one is a bare copper wire. The red and black wire carry 120 volts each, the white wire in usually your neutral which hooks up to your ground along with the bare wire.

Yes <<>> In North America, a three wire 120/240 volt system uses a neutral wire. For 240 volts two "hot" wires are used with no neutral.
current = voltage/resistanceAssuming the 240 volts is across the 100 ohm wire, 2.4 amperespower = current * voltageResulting in the wire dissipating 576 watts... One hot wire!

A #14 wire will do the job.
