Wiring
Wiring is an easy task which requires few simple methods to be undertaken. You could do this by yourself without having to the expertise of a professional which not only is costly but also expensive. Electronic devices vary in systems depending on their usage; this requires different types of wiring to be installed. Wiring is a segregating cable that transfers electricity. Wires for both industries and houses use a building wire whereas the wiring used in equipments is called an equipment wire. Wiring is measured by its diameter, this measurement generally referred to wire gauge. The measurement is calculated in a reversed order i.e. if the gauge number is higher, the diameter of the wire will be smaller.
Electrical wirings are regulated by codes. These codes were first laid out in the 1880s, the same year when extensive wiring work began. National Fire Protection Association constituted the National Electric Code (NEC) in 1897. The National Fire Protection Association is an umbrella of Insurance companies that were mainly concerned with the hazards of faulty electrical wiring. Wiring in the early days did not have insulation installed which reduces the risks of accidents occurring; these wires were mostly uncovered or covered with a cloth.
The NEC code is used in combination with other codes such as local, national and state level codes. The wiring codes emphasize on size and insulation of the wire. Some of the factors taken into consideration are the load that’s expected, frequency modifications and non corrosive nature. Wiring used for commercial purposes requires load demands to be of a higher level and the variations to be inconsistent. Industrial wiring will have a much higher demand and the variations will be frequent, the nature will be very volatile.
The usage of materials in wiring has changed over the years. Copper wiring material is a good conductor of electricity and widely used even today. Aluminum replaced copper in 1960s to 1970s due to the rise in price of copper. Later on insulation was used in wiring as it prevents damage however the rubber that was used in the process of making insulation is prone to moisture. In recent times rubber is replaced with PVC as wire insulation.
Electric wiring has now expanded to different segregating cables. When a wire is connected to another cable, the point of where the connection takes place is highly prone to electric sparks. It needs to be handled with caution and made sure that the insulation is firm.
