well that all depends when your dealing with what voltage is being applied to your motor,home, or building. the phase conductor in A panel box can be labeled with either red, or blue tape meaning that's the phase conductor or hot. This all comes down to with what type of electrical equipment or service your working with, The word phase just means that's the hot side and the hot side is usually the black wire, although a red or blue wire can to. Plus a wire being the hot conductor, or load the NEC likes to call it the phase conductor.
CommentThe term 'phase' conductor, in this context, is incorrect. The correct term is 'line' conductor.

What color are the phase neutral and earth cores in flexible cords?
It depends on the electrical standards of the country in which you live. In Europe, for example, the line conductor(not 'phase conductor'!) is brown, the neutral conductor is blue, and the earth conductor* is green/yellow stripe.[*properly called a 'protective conductor']
What is the purpose of a phase conductor?
There is no such thing as a 'phase conductor'; the correct term is 'line conductor'. In a single-phase system, the line conductor is the energised conductor; in a three-phase system, there are three (energised) line conductors.
What is phase conductor?
There is no such thing as a 'phase conductor'. The correct term is 'line conductor'. Line conductors are the three energised conductors that supply a three-phase load.
Can you use phase voltage as a single phase?
A single phase supply can be obtained between any pair of line conductors or between a line conductor and a neutral conductor.
Is current from a generator flows through the phase line and return through neutral to generator?
Yes, except that the correct term is 'line' conductor, not a 'phase' conductor.
How many wires are in a 3 phase circuit?
A ground, or earth, conductor is never included in the conductor count. So, a three-phase, three-wire, system has three line conductors, whereas a three-phase, four-wire system, has three line conductors and a neutral conductor.
What color can an underground conductor not be?
an underground conductor can be any color except white, grey or green.
How many wire or core in three phase electrical connection and single-phase electrical connection?
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.
Is there a neutral conductor in a 3 phase 4 wire wye system?
no
What is the voltage for each leg on a 480v 3-phase pannel phase to neutral?
Only one neutral conductor is typically in a 3 phase panel.
What is the color assigned to the high leg conductor of a 4-wire delta secondary three phases?
Assuming you are talking about a 120/240v delta system the color coding is as follows. Phase A(120v)-Black Phase B(208v "Wild leg/High phase")-Orange Phase C(120v)-Blue There are other color coding methods but this is the most common.
What color is single phase electrical supply?
In the US system, the hot phase is designated by a color other than white, except that bare or green is non-current carrying, or safety, ground. In a 120/240 split phase system, the most common home system, hot is black in a 120 volt circuit, and the two hots are black and red in a 240 volt circuit. Also, switched hot in a 120 volt circuit is red, but it does not really matter as the rule is "white is neutral" and "non-white is hot".Can someone add to this, please, for the UK and other systems.Answer'Phases' are not identified in three-phase systems. Colours, letters, or numerals are used to identify lines. The UK's and other EU countries' nominal single-phase supply voltage is 230 V at 50 Hz. The conductors are identfied as follows in line with EU standards:line (not 'phase') conductor brownneutral conductor blueprotective conductor green/yellow stripeFor three-phase (400/230 V) systems, the line conductors are coloured brown, black, and grey.Prior to the EU harmonisation requirements, the UK's single-phase conductors were coloured as follows, and these will be found in all installations that pre-date the EU requirements:line conductor redneutral conductor blackprotective conductor greenFor three-phase systems, the line conductors were coloured red, yellow, and blue.
