Electric wiring is a means by which a consumer of electric energy can operate his items of electrical equipment as and when he wishes. The wiring extends from the consumer's terminals, where it is connected to the electricity supply mains, to the various outlet points such as ceiling roses and wall sockets. The term fixed wiring is often used to distinguish the wiring serving the fixed outlet points from flexible wiring such as that attached to appliances, familiarly known as leads.
Electric Wiring includes cables as well as the equipment to control and protect. The cables are made up of conductors insulation, and occasionally mechanical protection.
The primary function of a conduit is to transmit the electric current, and it's thus made up with a material that offers minimal obstruction to electricity like the copper and aluminum. The conductor typically takes the form of one wire or several wires (known as strands) that are in contact with one with each.
The main function for insulations is to stop the current from flowing out of the conductor in areas where it is not needed to flow. Therefore, a material that provides a very resistant flow of current is employed to create the insulation, for instance, polyvinyl chloride (p.v.c.) or magnesia (mineral).
