Electrical wiring is a process of connecting different accessories for the distribution of electrical energy from the supplier to various appliances and equipment at home like television, lamps, air conditioners, etc.

Let us look at the different types of electrical wiring that are used in domestic properties.

5 Different Types of House Electrical Wiring Systems

  1. Cleat Wiring

This wiring comprises of PVC insulated wires or ordinary VIR that are braided and compounded. They are held on walls and ceilings using porcelain cleats with groves, wood or plastic. It is a temporary wiring system, therefore making it unsuitable for domestic premises. Moreover, cleat wiring system is rarely being used these days.

  1. Casing and Capping Wiring

It was quite popular in the past but it is considered obsolete these days due to the popularity of the conduit and sheathed wiring system. The cables used in this electric wiring were PVC, VIR or any other approved insulated cables. The cables were carried through the wooden casing enclosures, where the casing was made of a strip of wood with parallel grooves cut lengthwise for accommodating the cables.

  1. Batten Wiring

This is when a single electrical wire or a group of wires are laid over a wooden batten. The wires are held to the batten using a brass clip and spaced at an interval of 10 cm for horizontal runs and 15 cm for vertical runs.

  1. Lead Sheathed Wiring

Lead sheathed wiring uses conductors which are insulated with VIR and are covered with an outer sheath of lead aluminum alloy which contains about 95% lead. The metal sheath gives protection to cables from mechanical damage, moisture and atmospheric corrosion.

  1. Conduit Wiring

There are two types of conduit wiring according to pipe installation:

  • Surface Conduit Wiring

When GI or PVC conduits are installed on walls or roof, it is known as surface conduit wiring. The conduits are attached to the walls with a 2-hole strap and base clip at regular distances. Electrical wires are laid inside the conduits.

  • Concealed Conduit Wiring

When the conduits are hidden inside the wall slots or chiseled brick wall, it is called concealed conduit wiring. Electrical wires are laid inside the conduits. This is popular since it is stronger and more aesthetically appealing.

Here are some Advantages and Disadvantages of Concealed Conduit Wiring System


  • It is a safe wiring system
  • Safe from chemical effects, humidity and other external factors
  • No risk of shock
  • It is aesthetically appealing
  • No risk of wear and tear, fire or damaged cable insulation
  • Quite reliable
  • Renovations can be easily performed as you can replace old wires easily


  • Expensive as compared to surface conduit wiring
  • Changing the location of switches or appliances is difficult
  • Installation is complex
  • Hard to find defects in the wiring
  • Adding additional conduit in future is a tedious task

When the wiring is not done properly or isn’t maintained well, it may lead to dangerous situations such as electrical fires. Therefore, it is important that you take a lot of care while installing electrical wires and cables.
