There are different types of wirings used for connecting the loads to the mains, which can be used for house electrical wiring as well as industrial electrical wiring.

Some of these are discussed below. Electrical Wiring is an important part of a building, be it a residential building individual houses or apartmentslarge commercial spaces office buildings or industries factories. There are several methods and systems of Electrical Wiring, which are used for lighting and other power circuits. The type of Electrical Wiring plays a major role in the overall cost of the installation. So, it is very important to understand what type of Electrical Wiring Systems are suitable for a particular job.

Irrespective of the type of Wiring and the choice of Wire, the Electrical Wiring System should be able to protect against regular mechanical wear and tear under normal operating conditions.

Usually, the type of wire determines the Electrical Wiring Systems or at least their classification. In this, porcelain, wood or plastic cleats are fixed to walls or ceilings at regular intervals, i. PVC insulated cables are taken through the holes of each cleat and hence, the cleat supports and holds the wire.

This is an inexpensive method of wiring and is used for temporary installations. Therefore, it is not suitable for home electrical wiring and also it is an outdated method.

In this, cable is run through a wooden casing having grooves. The wood casing is prepared in such a way that it is of a required fixed length with parallel grooves that accommodates the cables. The wooden casing is fixed to the walls or ceiling with screws. After placing the cables inside the grooves of casing, a wooden cap with grooves obsa jireenya placed on it to cover the cables.

This is also a cheap wiring system, but there is a high risk of fire in case of short circuits. In this, insulated wires are run through the straight teak wooden battens. The wooden battens are fixed on the ceilings or walls by plugs and screws. The cables are fitted onto the battens by using tinned brass link clips.Below are a few of the most noteworthy changes that have been incorporated into the NEC.
