Electrical Wiring Classification-A Must Read Comprehensive Article

Electrical Wiring Classification
Today we will talk about the types of wiring system or Electrical Wiring Classification. The wiring system is a method by which we transport electricity from the electric meter or power supply to various installed appliances via wires.

These are some basic factors to be considered while selecting wiring system:

  • Initial Cost
  • Durability
  • Appearance
  • Mechanical Protection
  • Safety From Fire
  • Accessibility
  • Life

Electrical Wiring Classification:

Electrical Wiring Systems are classified into four types, as given below:

  1. Cleat Wiring System
  2. Casing-Capping Wiring
  3. Batten Wiring
  4. Conduit Wiring

Casing Capping Wiring System is sub-divided in two types:-

  1. Wooden Casing-Capping
  2. PVC Casing-Capping

In the same way, Conduit Wiring System is further sub-divided into two types:

  1. Surface Conduit Wiring (installed inside the wall surface)
  2. Concealed Conduit Wiring (installed outside the wall surface, also known as underground wiring)


Cleat Wiring System:

It is a temporary wiring in which wires are laid from one place to other through cleats. As shown in the picture, there are two parts: one is the upper cleat and the other is lower cleat and there are 2 or 3 recesses for passing wire in between the cleats.

At first, the lower cleat is screwed to the wall, then wires are seated in recesses and then the upper cleat is screwed over the lower cleat.

Types of Cleats: There are two types of Cleats (Double passage cleat and triple passage cleat)

Caution: The difference between two cleats in wiring must not be more than 60cm.

This type of wiring is done over the wall surface and it is not even much good in appearance.  Generally, this system is not used in homes. It is used for temporary requirements. For example: in marriage, party, construction work etc.

Batten Wiring System:

In this wiring, the wires are laid over Wooden Battens to spread from one place to other. At first, wooden battens are installed in the required places and then wires are clipped on them as shown in the given picture. This wiring is also not so good in appearance.

Casing-Capping Wiring System:

Next system of wiring is Casing-capping wiring which is being used at large scale nowadays. In this wiring, wires are carried from one place to other through the casing and then capping is done over casing as shown in the picture. The lower part is called casing and the upper part is called Capping.

Casing-Capping is also further divided into two types:

  • Wooden Casing-Capping
  • PVC Casing-Capping

Nowadays, PVC casing-capping is being mostly used.

In this wiring, at first, a diagram is made by drawing lines on places where wires are needed to be placed. Then Casing is screwed over those lines and capping is done after placing wires in the casing.

Conduit Wiring System:

Now let’s talk about Conduit Wiring. In this, wires are carried from one place to other through pipes. These pipes may be made up of iron or PVC.  Conduit wiring is also of two types:

  • Surface Conduit Wiring (Pipes are placed over the surface of walls through clamps and the wires are drawn through them)
  • Concealed Conduit Wiring (Pipes are placed under the surface of walls during the construction work of building and the wires are drawn after construction)

Conduit Wiring is considered to be the best and the most reliable wiring system, so being used at the most.

So this was my complete detail on Electrical Wiring Classification. I hope you enjoyed reading this article.
