The internal 3-core and earth electrical cable colours comprise a live brown wire, a neutral grey wire, a green/yellow protective earth wire and an additional black conductor which we have discussed as the live line 2 wire.
Is black neutral or live?
liveBlack Electrical Wires Any circuit's black wire should be considered live at all times. These wires are often used as a switch leg that transfers power to switches and outlets in all circuits. Black wires are never used for a ground or neutral wire and are meant to be used as the power feed for a switch or an outlet.
How do I identify a phase wire?
In a single-phase system, you will find that the two hot wires are colored black and red in most cases, though sometimes they are only black. In a three-phase system, the three hot wires are black, blue, and red. As with any electrical system, however, you cannot count on the fact that the wires were colored correctly.
Which wire is red or black?
Black wires are hot wires that run to the electrical outlet from the switch. Red wires are hot wires common in a 240-volt outlet or when a wall switch controls the outlet. Blue and yellow wires are hot wires for ceiling fans and three- or four-way switches. White or gray electrical wires are neutral wires.
What is colour code used for phase wire?
The commonly used color code is as follows: For a three-phase supply – Red, white and blue colours are used. For a single-phase supply – Red or brown is used for line and black or sky blue is used for neutral. For Earth or protective conductor – Green/Yellow or Green or bare copper conductor can be used.

Does Russia use gray or purple?
Russia was following the same wiring color codes as China before but they adapted the IEC with little bit changes i.e. in a three phase system, they may use purple or gray color instead of gray in IEC. As things are little bit changed in Russia, so one must follow the tester before going in the mess.

What color is the ground for DC power?
US DC power: The US National Electrical Code (for both AC and DC) mandates that the grounded neutral conductor of a power system be white or grey. The protective ground must be bare, green or green-yellow striped. Hot (active) wires may be any other colors except these.
What color is the protective ground?
The protective ground is green or green with yellow stripe. The neutral is white, the hot (live or active) single phase wires are black , and red in the case of a second active. Three-phase lines are red, black, and blue.
What color wire should I use for a hot wire?
However, common practice (per local electrical inspectors) is for the first hot (live or active) wire to be black and the second hot to be red. The recommendations in Table below are by Wiles. He makes no recommendation for ungrounded power system colors.
