Electrical Wiring

Electrical wiring is a method in which conductors, switches, meters and other devices carry electricity. Electrical wiring consists of cables and devices for protection and control. The various types of electrical wiring usually differ according to three factors: purpose, location and amount of electricity to be carried.

Electrical wiring consists of cables with integrated apparatus for protection and control. Cables are made of insulation, conductors and sometimes mechanical protection. The electrical conductor is typically in the form of either a single wire or a group of wires in contact with each other known as strands. Mechanical protection may be an overall sheath of insulating metal or material, or may be the cable will be enclosed within a duct, trunking or conduit. Conductors and insulators enclosed within the cable provided with mechanical protection are each defined as a core.

The wire being used is also called as an electrical conductor. It is typically made of copper and other materials that are capable of transmitting electric current. Generally, a wire is insulated; this is to protect the conductor from possible damages. The insulation is made from materials like fiber and plastic. The purpose of the insulation is to keep the current from dripping away from the electrical conductor at areas where current is not needed to flow. Additionally, the type of insulation to be used generally depends on the location where the electrical wiring is to be set up.

The type of cables and wires that are used in electrical wiring systems follows an international standard called International Electrotechnical Commission. This international standard is maintained to reduce the possible hazardous confusion of safety wires with other electrical wires. This allows laymen and electricians to recognize and understand what type of wires an electrical system will comprise. For an instance, color coding is used to help categorize wires for installation, safety, and repair purposes.

All wiring safety codes implement a color configuration for the insulation of conductors. Various electrical codes recognize or sometimes require the utilization of wires with green color insulation with additional yellow stripe used for grounding for safety purposes. An electrical code is a set of rules for electrical wiring.

One of the types of electrical wiring is stranded wires. It is often utilized in homes. This type of electrical wiring comprises of a number of solid wires of small gauges wrapped around a central wire. The stranded wire is capable of increasing the amount of electrical power that the wire can carry. This type of wire is often utilized as it is easy to shape and flexible, which is the perfect solution for fitting electrical wiring behind walls.

Electrical wiring that are to be installed outdoors must be able to withstand environmental factors and elements. Typical insulators for outdoor electrical wiring include thermoplastics. Insulators that have resistance to ultra-violet rays should be installed on this type of electrical wiring.

Electrical wiring systems in a family home are simple with fairly low power needs, seldom changes to the building layout and structure, often with moderate temperature and safe environmental setting. In a commercial facility, more repeated wiring modifications can be expected, large devices and apparatus can be set up and unusual conditions of moisture and heat may pertain. Some heavy industries have more challenging wiring needs, including larger currents and higher levels of voltages and more frequent changes of equipment installations, hazardous, explosive or damp and unstable atmospheres.
