In the United Kingdom, the earth wire was green and yellow (or bare), the live wire was red, and the neutral wire was black. In North America, the term "red" refers to the metal in the cable, not to the color of clothing worn by workers who install wiring.
The word "red" is also used in reference to electricity that has a high potential of causing harm if it enters your body through your hands or feet. This type of current is called "red hot" because it can cause serious damage to flesh if you contact it.
In general, electricity at room temperature is considered to be a safe voltage level to be exposed to human skin. The typical household wall outlet provides about 120 volts AC (alternating current) with no more than 6 milliamps of current flowing through it. That's less than what's needed to light a light bulb and too low to cause any pain. But just in case, do not touch any part of your body without first checking that you're not being given an electric shock.
If you come into contact with electricity, say, from a power line truck, radio-controlled car, or science project kit, get away from the source of danger immediately. Don't try to pull it off of someone else!
Dave, an Electrical Safety Expert, responded. The living red turns brown. The neutral black is transformed into blue. The earth's cables remain green and yellow. These colors should be used on all equipment that might present a danger if contacted by electric current.
The active wire (high potential) is brown in color (it used to be red). Blue is the color of the neutral wire (low voltage). The earth wire is green and yellow striped (it used to be only green).
An electrical system is called neutral-grounded if the ground conductor is also called a neutral. This provides an alternative path for current to follow in case of a problem with one branch of the circuit. The term "neutral" does not have any technical meaning other than it must be included as part of the hot line pair. If you remove the neutral from a house wiring system, all you have left is normal, unsafe work practice: a single, parallel path for current to follow if something goes wrong.
In general, electricity travels from high to low, so the active side of the cable should be the side closer to high voltage. However, since electricity can also travel from low to high, or both, this fact must be taken into account when selecting which wires will be the active/hot portion of the circuit. For example, in a three-wire system where the third wire is always the ground, the active/hot portion could be either the first or second wire depending on whether the connection is between two houses sharing a common neutral, or one house and another piece of equipment such as a meter panel or electric vehicle charger.
Electricity in Australia is delivered at 240V and 50Hz.
The term "live" means the cable is capable of carrying a current. The term "neutral" means it doesn't carry current but is part of the circuit anyway. Neutral and hot wires cannot be mixed without any serious consequences.
In Australian buildings, if you're not sure which wire is which, just touch them to see what happens! If one is hot and one is cold, you have a problem with your wiring system. If both are warm, then there's nothing wrong with your wiring.
The term "building wiring" refers to the electrical system within the walls and ceilings of a building. It differs from household wiring in that there are multiple circuits required for appliances such as air conditioners, heaters, and fans. These devices require more than one conductor to operate. The conductors must be able to carry enough current to power the device while protecting other objects from overheating or burning down due to excessive current flow.
Building wiring also requires special protection against electrical hazards such as exposed metal surfaces or broken or frayed insulation on cables. This is accomplished through use of junction boxes and circuit breakers.
The colors are as follows: Positive: The positive current wire is red. Negative: The negative current wire is black. Neutral: The white wire is neutral.
A neutral can be used with a ground fault circuit interrupter (GFCI) or with other equipment that requires neutral to be grounded. If you're not sure if your home was wired with neutrals, ask your electrician before you do any work. This will help prevent accidents such as electrocution.
Back then, like most countries around the world, buildings weren't required by law to have electrical wiring. So if a building's owner wanted more flexibility in placing outlets, he or she would connect one set of wires to the wall panel, calling them "hot," and leave the other set alone. These wires were then considered part of the building's electrical system, but they were never connected to the network side of things so they didn't help supply electricity to neighbors' homes; they were only useful for supplying power to this one.
English red is an iron oxide pigment that produces the colors red, brownish-red, and pink. The color of iron oxide pigments depends on the chemical composition of iron and oxygen. Other minerals can be found in English red. The term "English red" refers to a pigment that is somewhat lighter than iron oxide red. English red was formerly called "brickdust".
In art history, English red dates back at least as early as Roman times. It was usually made from ground up iron oxides mixed with water and sometimes other substances to improve its drying properties or to adjust its color. The most important source for English red today is siderite, which contains mostly iron oxide, some carbon, and small amounts of calcium, magnesium, and potassium.
In chemistry, English red means a compound containing iron(II) ions that have been oxidized to form hydrous ferric oxide. Although this material is not pure red, it does show significant red coloration. Modern commercial sources of English red include litharge (75% zinc white, 25% lead white), troilite (70% iron, 30% sulfur), and hematite (iron ore).
In biology, English red means any one of several red blood cells disorders in which the cells contain abnormal amounts of hemoglobin. The three main types are polycythemia vera, idiopathic red cell fragmentation, and benzene poisoning.
