Conduit Wiring: Advantages and Disadvantages

wiring electrical system conduit safety installation

This page covers the basics of conduit wiring along with its pros and cons. It outlines the benefits and drawbacks of using conduit wiring in electrical systems.

What is Conduit Wiring?

Conduits serve as protective pathways for electrical wiring within an electrical system. They are typically manufactured from materials like plastic, metal, or fiber, and can be either rigid or flexible depending on the application.

Conduit installations must adhere to standard regulations to ensure safety and functionality. For workshops and public buildings, conduit wiring is often considered the best and most desirable wiring system due to the enhanced protection and safety it offers, particularly against fire hazards.

Types of Conduits

Here are the common types of conduits used:

  • Class A Conduit: Constructed from a thin layered steel sheet of low gauge.
  • Class B Conduit: Made from a thicker steel sheet of high gauge.

Materials Used in Conduit Wiring

The following materials are commonly used in conduit wiring installations:

  • GI (Galvanised Iron) wire
  • Elbow
  • Coupling
  • VIR or PVC insulated cables
  • Lock nut
  • Clip
  • Junction Box

Benefits (Advantages) of Conduit Wiring

Here’s a list of the advantages of using conduit wiring:

  • Safe: Provides a high degree of protection for electrical wires.
  • Better appearance: Offers a cleaner and more organized look compared to other wiring methods.
  • No risk of fire: Significantly reduces the risk of electrical fires.
  • No risk of damage to cable insulation: Protects the wiring from physical damage that could compromise the insulation.
  • Safe from humidity, smoke, steam, etc.: Provides excellent protection against environmental factors.
  • No risk of shock: Minimizes the risk of electric shock.
  • Long lasting: Conduit systems are typically durable and have a long service life.

Drawbacks (Disadvantages) of Conduit Wiring

While conduit wiring offers many benefits, it also has some disadvantages:

  • Expensive: Conduit systems generally have higher material and installation costs compared to other wiring methods.
  • Installation is not easy: Installing conduit requires specialized skills and tools, making it more complex than other wiring methods.
  • Not easily customizable: Modifying or expanding a conduit system can be challenging.
  • Hard to detect faults: Locating faults within a conduit system can be more difficult compared to open wiring systems.
