In Europe, the standard color for the protective (earth) conductor is a green/yellow stripe, although in most residential two-core (line and neutral; the protective conductor isn't counted) wiring, the protective conductor is bare.

In the electrical system of the US what is the difference between the neutral and the PE Ground?

US NEC: The neutral conductor is an insulated grounded conductor used as the current return in a circuit. The color designation for neutral is white. The protective ground (PE, protective - earth) is a non-insultated grounding conductor used to shunt fault current to ground, tripping the protective device. The color designation for PE ground is green. Neutral and PE ground are tied together at the distribution panel. PE ground is also connected to a solid earth ground, such as grounding rods driven into the earth. Downstream of the distribution panel, PE ground is never used to carry operational current. Any current flow on PE Ground, other than parasitic current, is considered a ground fault, which must be corrected. In fact, GFCI (Ground Fault Current Interrupting) breakers will trip when neutral current does not match hot current, an indication of PE ground current flow.


What is the 2nd hot wire color is for 230V single phase for Europe?

In North America, residential supplies comprise two line ('hot') conductors and a neutral. The nominal potential difference between the two line conductors is 240 V, and the nominal potential difference between each of the line conductors and the neutral conductor is 120 V. Heavy appliances operate at 240 V, while most other appliances operate at 120 V.Unlike North America, however, a European single-phase residential system comprises a single line conductor and a neutral conductor, with a nominal potential difference of 230 V. All appliances then operate at 230 V. The line conductor insulation colour is brown, the neutral is blue, and the earth (ground) is either bare or covered with yellow and green striped insulation.For three-phase systems, the EU Harmonisation standard is:Three-phase line conductors: brown/black/greyNeutral conductor: blueEarth (protective) conductor: green with yellow stripe


Why colour burst required in TV?

The 8 cycle color burst pulse on the back porch of the horizontal retrace pulse of the NTSC signal is required in order to maintain phase lock synchronization between the transmitter's chroma modulator and the receiver's chroma demodulator.


Is American color coding and British color coding are same?

No, American and British color coding for electrical conductors is not the same.UK, AC: The United Kingdom now follows the IEC AC wiring color codes. Table below lists these along with the obsolete domestic color codes. For adding new colored wiring to existing old colored wiring see Cook. [PCk]UK AC power circuit wiring color codes.US, AC:The US National Electrical Code only mandates white (or grey) for the neutral power conductor and bare copper, green, or green with yellow stripe for the protective ground. In principle any other colors except these may be used for the power conductors. The colors adopted as local practice are shown in Table below. Black, red, and blue are used for 208 VAC three-phase; brown, orange and yellow are used for 480 VAC. Conductors larger than #6 AWG are only available in black and are color taped at the ends.US AC power circuit wiring color codes.FunctionlabelColor, commonColor, alternativeProtective groundPGbare, green, or green-yellowgreenNeutralNwhitegreyLine, single phaseLblack or red (2nd hot)Line, 3-phaseL1blackbrownLine, 3-phaseL2redorangeLine, 3-phaseL3blueyellowFunctionlabelColor, IECOld UK colorProtective earthPEgreen-yellowgreen-yellowNeutralNblueblackLine, single phaseLbrownredLine, 3-phaseL1brownredLine, 3-phaseL2blackyellowLine, 3-phaseL3greyblue


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 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']
