Wire: A wire is a single conductor, that the material is most commonly being copper or aluminium. The wire is used to carry electricity to bear the mechanisms load to transmittelecommunications signals. Mostly wires are used for heating jewellery, clothing, automotive or any industrial manufactured parts like pins, bulbs and needles. There are different types of wires serving different purposes. Most commonly used wires for household electrical wiring is copper and aluminium wires.
Cable: The cable is two or more insulated wires wrapped in one jacket. These cables are classified by the number of conductors it’s made up from. A cable is used for power transmission for telecommunications signals or to carry electricity.The three most commonly used cables for communications are twisted pair, coaxial and fibre optic cables. Among them, twisted pair Ethernet cable is the most commonly used cableto connect routers or modems to computer.
The fixing wiring which runs through the walls or ceiling between the fixture and the power supply is known as cables whereas wires are used to connect portable appliances such as lamps, charger etc. This is easy to understand the difference between wires and cable.Let us understand in detail about core cables.
A detailed study of lighting and power cables:
To use lights and appliance, we need to connect then to the main power supply. Cables come in different sizes; the size refers to the cross-sectional area of the cores. This will vary depending on the amount of current flowing through them. Cables are flat with curved sides and have two to four cores within them like 2 core cables and 3 cores cables and many more. Let us discuss the different types of cables and their typical applications.
Single-phase power cables:
Two cores cables and earth cables:This cable will connect the consumer unit to the power outlet sockets and carries the electricity to appliances which are plugged into the socket. The cable has three cores that is the live core, a neutral core and the earth core. The live and neutral cores are insulated and carry the current to and from the socket.
Three core flex cable: This type of cable is used to connect appliances such as lamps and other extensions cables to the power socket. The flex cable has three cores being live core, earth core and neutral core.
Two core flex cable: This type of cable is used to connect small appliances which are double insulated and need no earth. The cable has only two core being live and neutral. As this is a 2 core cable it can be of circulator shape.
Safety is very important, if your installation of wires and cable is not proper, it could lead to accidents.Before you start any electrical project that includes wiring and cabling, you need to obtain permission from your local building inspector to avoid such situation. Make sure you use appropriate wires or cables suggested by them based on your needs.
