2. Electrical wiring in North America - Wikipedia

   en.wikipedia.org/wiki/Electrical_wiring_in_North...

   With transparent cord the hot wire is copper colored, and the neutral is silver colored. Grounding wire of circuit may be bare or identified insulated wire of green or green having yellow stripes. All metallic systems in a building are to be bonded to the building grounding system, such as water, natural gas, HVAC piping, and others.

3. Copper conductor - Wikipedia

   en.wikipedia.org/wiki/Copper_conductor

   Electrical conductivity is a measure of how well a material transports an electric charge. This is an essential property in electrical wiring systems. Copper has the highest electrical conductivity rating of all non- precious metals: the electrical resistivity of copper = 16.78 nΩ•m at 20 °C. The theory of metals in their solid state [7 ...

4. Electrical wiring - Wikipedia

   en.wikipedia.org/wiki/Electrical_wiring

   Electrical wiring is an electrical installation of cabling and associated devices such as switches, distribution boards, sockets, and light fittings in a structure. Wiring is subject to safety standards for design and installation. Allowable wire and cable types and sizes are specified according to the circuit operating voltage and electric ...

5. Home wiring - Wikipedia

   en.wikipedia.org/wiki/Home_wiring

   Home wiring. Homes typically have several kinds of home wiring, including electrical wiring for lighting and power distribution, permanently installed and portable appliances, telephone systems, heating or ventilation system control, and increasingly for home theatre and computer networks. [1]

6. Knob-and-tube wiring - Wikipedia

   en.wikipedia.org/wiki/Knob-and-tube_wiring

   Earthing systems. v. t. e. Knob-and-tube wiring (sometimes abbreviated K&T) is an early standardized method of electrical wiring in buildings, in common use in North America from about 1880 to the 1930s. [1][2] It consisted of single-insulated copper conductors run within wall or ceiling cavities, passing through joist and stud drill-holes via ...

7. Electrical conductor - Wikipedia

   en.wikipedia.org/wiki/Electrical_conductor

   t. e. In physics and electrical engineering, a conductor' is an object or type of material that allows the flow of charge (electric current) in one or more directions. Materials made of metal are common electrical conductors. The flow of negatively charged electrons generates electric current, positively charged holes, and positive or negative ...

8. Electrical code - Wikipedia

   en.wikipedia.org/wiki/Electrical_code

   Electrical installations. An electrical code is a term for a set of regulations for the design and installation of electrical wiring in a building. The intention of such regulations is to provide standards to ensure electrical wiring systems are safe for people and property, protecting them from electrical shock and fire hazards.

9. Mineral-insulated copper-clad cable - Wikipedia

   en.wikipedia.org/wiki/Mineral-insulated_copper...

   Conductor cross section area is 1.5 mm 2; overall diameter is 7.2 mm. Mineral-insulated copper-clad cable is a variety of electrical cable made from copper conductors inside a copper sheath, insulated by inorganic magnesium oxide powder. The name is often abbreviated to MICC or MI cable, and colloquially known as pyro (because the original ...
