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.
Gauge Wiring is made up of cables and associated protection. Conductors, insulation, and sometimes mechanical protection are all part of cables. Conductors are used to carry current. They are made of materials that resist the flow of electricity, such as aluminum or copper. Conductors are usually composed of one wire or a group (known as strands), that come in contact with one another.
The mechanical protection can be in the form of an integrated overall sheath made of metal or insulation material, or it may be contained within a conduit, trucking, or duct. Each core is made up of two or more insulated conductors that are encapsulated in a cable and protected by mechanical protection.
What is called a system of wiring will depend on the type of protection that was used. The most common types of wiring are p.v.c. The p.v.c. sheathed cables, insulated cable within conduits (either nonmetallic or metallic), and mineral-insulated metal shielded cables.
