To enable smooth supply of electricity and to ensure optimal electrical safety each wire or cable has to be installed carefully. The wires and cables are attached from the fuse box to the appliances and fixtures.
Let us understand the basic difference between wires and cables before we continue. Solid wires: These are composed of a single conductor and can further be classified as bare or insulated.
They are used for higher frequencies due to their low resistance property. Stranded wires: As the name rightly suggests, these wires are comprised of many thin strands of wires intertwined together. Their design makes them perfectly flexible and durable. Their cross-sectional area as compared to solid wires is much higher. They can broadly be classified as twisted cable, coaxial cable, multi conductor cable and fiber optic cable. Twisted Pair Cable: Imagine a braid.
These cables are generally used for signal transmission. Applications: telecommunications. Multi-conductor cables: The name reference clearly suggests the presence to two or more conductors. They are designed to safeguard signal integrity.
They have found their applications on instrumentation, communications etc. Coaxial cables: The core consists of a solid conductor surrounded axially with the foil conductor. These are separated by an insulating dielectric. Applications: TV cables. Fiber optics cables: With excellent bandwidth, they are capable of transmitting large amount of data.
They have recently gained momentum due to their low interference susceptibility. Following colour coding standards is essential and mandatory since each colour signifies a particular function of the wire. Red — Red wire indicates the phase in electric circuit which can be considered as a live wire. It must be kept in mind that a red wire can be connected to only red and black other wires.
Black — Black wires denotes neutral wire which is connected to neutral bus bar inside an electric panel. Note that black wire must be connected to black wire only. Colour coding for the cables is done to decipher active, neutral and earthing. There is no specific colour coding designated by NEC. Every country has its own norms and colour coding standards. If this number astounds you, note that saw over 11, electrical accidents in the country.
Nearly 4, of these accidents were fatal. Hence, always check the wiring and the devices before you start working on them to avoid electric shocks.
Get rid of the old wiring and choose carefully among plethora of options available including flame resistant, heat resistant etc. Amp checking is a must for all wiring during both installation and replacement. Understanding the grounding system is imperative. It helps redirect extra current in case there is a slip or fault. Following the wiring diagrams to ensure effortless work is the key.
Accidents can lead to irreparable damage. For instance, instead of using a single 10 AWG solid strand of copper one could also get a 10 AWG wire with 19 strands. Obviously, those 19 strands are not all 10 AWG or it would be much larger in diameter. The math is calculated to determine what size is needed for 19 strands to equal 1 strand of 10 AWG copper.
That way, both diameters of copper, solid or stranded, both exert the same amount of current. Typically, electrical wire used in homes or buildings does not come in a flexible option because the cables are installed and never touched again.
However, extension cords and power cables are uncoiled to be used for the day and the coiled back on to the reel for later use. Generator cables and welding cable come to mind as flexible cables with very thin stranding. If you need a flexible cable we can most definitely upgrade your electrical wire to a power cable. Just remember that power cables have a lot of design involved in them for outdoor wear and tear that feed into the price such as flexible stranding and thick rubber insulation.
