3 hrs confidence: peer agreement (net): +1
peer agreement (net): +1(insulated) wire, conductor or core Explanation: Gemeint sind hier Einzeladern oder Einzelleitungen Area Electric cables / Cabling IEV ref 461-04-04 en core insulated conductor assembly comprising a conductor with its own insulation (and screens if any) Note – In North American usage, the core of a cable has been defined as the assembly of components of a cable lying under a common covering such as the sheath. Such usage is deprecated. de Ader, f http://www.electropedia.org/iev/iev.nsf/display?openform&iev... Wiring tips for connections and routing inside industrial control panel : 2. Conductor and cable runs Conductors and cables should run from terminal to terminal without any intervening joins. : The protective conductor should as far as is possible be routed close to the associated live conductors to avoid undue loop resistance. : 3. Conductors of different circuits This refers to wires and cables that are in the same enclosure but are connected to different parts of the system, for example power wiring that could be carrying high currents at 415 volts. https://electrical-engineering-portal.com/tips-wiring-indust... Required functions and devices (UL 508A chap. 31.3.2) Disconnection This function must disconnect all ungrounded conductors of a circuit from their electrical supply. https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&c... NEC® 2008 Art. 110.2 specifies that all devices and wires shall be approved. This means approved by the Authority Having Jurisdiction (AHJ)(Electrical Inspector). : 4.1.3 Ground and neutral conductors Ground and neutral wires in the USA In the USA, the following terms are used: grounding wire (PE wire) and grounded wire (N wire). The grounding wire (green or green/yellow) shall not carry operational current. Each power circuit shall have a separate ground terminal. The grounded wire (white or gray) is used for the N wire (IEC). There are no PEN wires (PE and N) in the USA. If neutral wires (N) are used, these shall be clearly identified and fitted to a separate, insulated terminal. : 7.1 Color coding of the grounding conductor (PE) and the grounded conductor (N) Ground connection (Bonding Conductor) UL 508A Art. 17.4 Insulated grounding conductors shall be green, with or without one or more yellow stripes. Only grounding conductors shall be color coded in this way. : Grounded conductor, UL 508A Art. 17.4 Insulated grounded conductors shall be identified by white or gray insulation. Alternatively, any color other than green may be used, but in this case three white stripes will be required along the entire length. : Internal wiring Internal wiring for power circuits: laid by the industrial control panel builder. Compare with: "Factory Wiring" https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&c... Note: During my activity as electrical engineer I often dealt with international standards (IEC and UL for example) and know the corresponding terms by heart. -------------------------------------------------- Note added at 3 hrs (2018-07-16 11:20:03 GMT) -------------------------------------------------- Differences between "cable" and "wires/conductors": An electrical cable is an assembly of one or more wires running side by side or bundled, which is used to carry electric current. https://en.wikipedia.org/wiki/Electrical_cable 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 current capability, with further restrictions on the environmental conditions, such as ambient temperature range, moisture levels, and exposure to sunlight and chemicals. : In a typical electrical code, some colour-coding of wires is mandatory. Many local rules and exceptions exist per country, state or region.[1] Older installations vary in colour codes, and colours may fade with insulation exposure to heat, light and ageing. : The simplest form of cable has two insulated conductors twisted together to form a unit. Such un-jacketed cables with two (or more) conductors are used only for extra low voltage signal and control applications such as doorbell wiring. https://en.wikipedia.org/wiki/Electrical_wiring -------------------------------------------------- Note added at 1 day 6 hrs (2018-07-17 14:34:24 GMT) -------------------------------------------------- In order to learn, how main switch, circuit breakers and internal wiring is interconnected, please read the following articles: This unit would be an isolating switch (Load break switch) only and not a circuit breaker. A circuit breaker is designed to automatically open the circuit under an overload or short circuit situation. An isolating switch is a manually operated device to open and close the circuit and will not switch off automatically under overload situation : The Main Switch is just that. The "Big Daddy" switch that turns the power off to the whole of the electrical installation. The rating of the Main Switch refers to how much current it can switch. It normally doesn't have any overload protection capabilities. The Supply Authority will have their fuses between the consumers mains (the wires coming into your place) and the Main Switch as protection against catastrophic overload. After the Main Switch, power is distributed to the various circuits (lights, power, air conditioning, hot water etc) which are each protected by fuses, or more commonly these days by circuit breakers or combined circuit breaker/RCDs (residual current devices or "safety switches"). https://www.renovateforum.com/f195/confused-main-switch-vs-c... A distribution board (also known as panelboard, breaker panel, or electric panel) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits, while providing a protective fuse or circuit breaker for each circuit in a common enclosure. Normally, a main switch, and in recent boards, one or more residual-current devices (RCD) or residual current breakers with overcurrent protection (RCBO), are also incorporated. : The photograph to the right shows the interior of a residential service panelboard manufactured by General Electric. The three service conductors—two 'hot' lines and one neutral—can be seen coming in at the top. The neutral wire is connected to the neutral busbar to the left with all the white wires, and the two hot wires are attached to the main breaker. Below it are the two bus bars carrying the current between the main breaker and the two columns of branch circuit breakers, with each respective circuit's red and black hot wires leading off. Three wires (hot black, neutral white, and bare ground) can be seen exiting the left side of the enclosure running directly to a NEMA 5-15 electrical receptacle with a power cord plugged into it. The incoming bare, stranded ground wire can be seen near the bottom of the neutral bus bar. : This picture shows the interior of a typical distribution panel in the United Kingdom. The three incoming phase wires connect to the busbars via a main switch in the centre of the panel. On each side of the panel are two busbars, for neutral and earth. The incoming neutral connects to the lower busbar on the right side of the panel, which is in turn connected to the neutral busbar at the top left. The incoming earth wire connects to the lower busbar on the left side of the panel, which is in turn connected to the earth busbar at the top right. : The main distribution board in an installation will also normally provide a main switch (known as an incomer) which switches the phase and neutral lines for the whole supply. https://en.wikipedia.org/wiki/File:EEUU(GE)BreakerpanelInnar...
