Types of Wiring Systems

Hello friends, in today’s article we will look at the types of electrical wiring and discuss in detail the different methods of wiring.

What is Electrical Wiring?

Definition: Electrical Wiring is nothing but the process of combining all the lights, fans, televisions, motors running in our house and arranging the wire properly, and bringing it to the distribution board is known as electrical wiring.

Methods of Electrical Wiring Systems w.r.t Taking Connection:

Wiring is a system in which we can easily operate all the appliances in the house from the meter through the distribution system. This wiring can be done in two ways.

The two methods of wiring system are as follows:

  • Joint Box system or Tee system.
  • Loop-in the system.

#1. Joint Box or Tee or Jointing System:

Joint Box or Tee or Jointing System

To operate any of these devices under the Tee system or joint box system we take it jointly from the middle of the wire and give it to the tool or device that we cut into the wire is inside the cut box. Therefore less wire is used in this system.

This system does not require a large amount of wire, so the cost of this system is relatively low. But the money that is saved is used to buy a box so the equation of this matter of money becomes the same. This system is suitable for temporary installations and is inexpensive.

#2.Loop-in the System:

Loop-in system

This system is widely used in the market. In this system lights, fans, and any other device are connected in parallel. So that the power received by this system is received by each device individually. When new power is required on a light or switch, it is connected from board to board without giving any cut in the wire as opposed to the joint box system.

This one circuit is carried from board to board through series. Until the last board of this series arrives. In this system, the phase or line conductor is looped inside the switchboard or box. In any condition these wires should not be separated from each other otherwise the circuit of the front circuit will open and will not work.

Advantages of Loop-In Method of Wiring:

The advantages of the Loop-In Method are as follows:

  • It is easy to locate the fault. Because the circuit of the wire is obtained from board to board.
  • Combined boxes are no longer needed to save money.
  • In an in-loop system, no joint of wire is pressed into concealed.
Disadvantages of Loop-In Method of Wiring:

The disadvantages of the Loop-In Method are as follows:

  • The longer the wire in this system, the greater the voltage drop across the line.
  • Looping – usually becomes difficult in switches and lamp holders.

Types of Electrical Wiring Systems:

The types of internal wiring used in the market are as follows:

  • Cleat Wiring.
  • Lead Sheathed or Metal-Sheathed Wiring.
  • Wooden Casing and Capping Wiring.
  • Batten Wiring (CTS or TRS).
  • Conduit Wiring.

Types of wiring used depending on pipe installation.

  • Surface or Open Conduit Type.
  • Recessed or Concealed or Underground Type Conduit.

#1. Cleat Wiring:

Cleat Wiring

This wiring system uses VIR (Vulcanised Indian Rubber) or PVC (Polyvinyl chloride) wire. This wire is braided and compounded on walls or ceilings using porcelain clays.

This wire can be weatherproof. This is usually configured when wiring. At present this wiring is not used for home. This is because it is temporary wiring. It is used especially in temporary military campuses or festival-related pavilions.

Advantages of Cleat Wiring:

The benefits of Cleat Wiring are as follows:

  • The Cleat Wiring system is simple and easy to install.
  • The wiring underneath is obviously in the open air. So if there is a defect in a wire or cable, it can be repaired easily and quickly.
  • Improvements in the wiring can be easily added e.g. alteration and addition.
  • Since the work is in progress, it is used under construction for army camps.

Disadvantages of Cleat Wiring:

The disadvantages of Cleat Wiring are as follows:

  • This wiring is not used permanently as over time it becomes loose between the two clamps i.e. sag falls.
  • This is used at low temperatures only at 250/440 volts.
  • Looks bad compared to another wiring in appearance.
  • Since this wiring is exposed to air it can be damaged by moisture, sunlight, rain chemical, and acidic effect cable.
  • The possibility of electric shock and fire remains.
  • Not long life.
  • This is not used in a space of importance and sensitive space.

#2. Lead Sheathed or Metal-Sheathed Wiring:

This type of wiring allows the conductor. Which is insulated with VIR. It has about 95% lead aluminum alloy in the outer casing which protects the metal casing from moisture, mechanical damage, and atmospheric corrosion.

The entire lead covering is electrically seamless and is attached to the ground at the point of entry to protect against electrolytic action due to leakage and to provide safety if the casing comes alive.

The cable is run on a wooden bat and fixed by link clips just like the TRS wiring.

#3. Wooden Casing and Capping Wiring:

Casing and Capping Wiring

Casing capping This wiring has been used extensively in the past but since the introduction of concealed wiring, the demand for this has been very low. The cables used in this system are VIR (Vulcanised Indian Rubber) or PVC (Polyvinyl chloride) wire.

The cable is carried by enclosures of the wooden or plastic casing. . The cover is made of wood strip or plastic. The parallel groove is cut in the direction of length so that the VIR cable can be easily accommodated. Grooves were made to separate the anti-polarity. Capping (also made of wood or plastic) is used to install and fit wires and cables into the casing.

Advantages of Casing Capping Wiring:

The advantages of Casing Capping Wiring are as follows:

  • Is a strong and long-lasting wiring method.
  • Inexpensive and easy to install the system.
  • Customization in wiring can be done easily.
  • Being fixed in the cover protects from smoke, dust, rain, and steam, etc.
  • Having a cover on the wire does not create a shock-like condition.
  • This can be easily repaired if the phase and neutral slots are separated.

Disadvantages Casing Capping Wiring:

The disadvantages of casing capping wiring are as follows:

  • Maintenance becomes more expensive.
  • Not suitable for weather conditions with high humidity and acidic conditions.
  • The risk of the fire remains high.
  • Content is not easily found in the contemporary Part.
  • Locusts damage wood coverings and capping.
