Wiring is not a duck soup. Period. If you are among those freebies, who want to do wiring just because their neighbors are doing it, you are on a wrong trail. Wiring is a very serious subject and it’s better to get some information about basicelectrical wiring before you step into it. Any gaffe can burn down your beautiful house in a few minutes. It is a common fact that people get confused when they are cabling for the first time. Gathering some information about circuits, wires and electrical grid is very essential when you plan to do wiring yourself.
Basic House Wiring
Follow Local Electrical Code
If proper precautions are not taken, electricity can be fatal. Follow the local codes and regulations regarding residential wiring have been put in place. They are framed to protect you.
Components of Basic House Wiring
There are three basic components of basic electric wiring. These are - service entry, branch circuit and panel board.
The point in the house where the electrical service goes from the main grid into the home is called as ‘service entry’. Service entry is considered as a critical point in basic electrical wiring. You must make sure that the entry lines are at least ten feet above the ground and inaccessible from the window. It should be free of obstructions like tree branches. The service entry should be installed in the right way that water cannot penetrate the accent point.
A panel board is considered to be the control centre when it comes to electrical wiring. Whenever you install a new electronic device in your house or planning to do some additional wiring, you should be checking the panel board to ensure the electricity is cut off when the electrician starts working. Panel board is the device where you should install new breakers when you are doing a wiring remodeling in your home.
The isolated areas of the home where the panel board directs the electrical currents are called branch circuits. Due to the functioning of branch circuits, one can turn off the power in one section of the house, say kitchen, when rest of the house is in operational mode. The electrician should understand how the branch circuits works to get the basic wiring in home done.
Electric wire colour coding:
Before you can make electrical connections, you must first know what type wire to use for the installation, what color wire is needed for the application, and what is the proper size wire to handle the load of the circuit. For electricians, wire colors mean everything. They identify whether the wire is a hot, neutral, or a ground wire.
Having the right sized wire to handle the ampacity flowing through it is just as important. The size of wire also varies, depending on which type of wire you are installing. By following these steps, you'll be installing electrical circuits the right way and have a safer home because of it.
Electrical Wire Markings
Electrical wires have markings stamped or printed on the outside sheath of the cable. These markings tell what type and size of wire that you have. But looking deeper, the color of the wires inside of the sheath, like in type NM cable, will reveal that different color wires serve different purposes.
Black wires are always used for hot wires. These wires may feed a switch or outlet and are often used as switch legs. Never used a black wire for a neutral or ground connection.
Red wires are also used for hot wires, switch legs (like to a ceiling fan), and are the second hot wire in 220-volt installations. Another useful application is the interconnect wire between twohardwired smoke detectors.
Blue and Yellow Wires
Blue and yellow wires are used as hot wires. These wires are usually pulled in conduit. The blue wires are generally used for travelers in three-way and four-way switch applications. They also are used as switch legs to things like lights...
