Step 7: Make Electrical Connections

Step 8: Test the Wiring System

Step 9: Cover the Wall Grooves

Let us look at the step-by-step installation procedure of a concealed conduit electrical wiring system.

Step-by-Step Process to Install a Concealed Conduit Wiring System

Step 1: Plan the Electrical Layout

The first step is preparing the wiring layout plan.

What to Include in the Plan

  • Switch locations
  • Socket outlets
  • Light points
  • Fan points
  • Distribution board position
  • Appliance connections

Careful planning helps reduce wiring complications and future maintenance issues.

Step 2: Mark Conduit Routes on Walls

After finalizing the layout, mark the conduit paths on walls and ceilings.

Important Considerations

  • Keep conduit routes straight whenever possible
  • Avoid unnecessary bends
  • Maintain proper spacing between power and communication lines
  • Ensure accessibility for junction boxes

Proper marking improves installation accuracy.

Step 3: Create Wall Grooves

Wall grooves or channels are cut to install the conduits inside the walls.

Common Methods

  • Wall chaser machine
  • Hammer and chisel

Important Tips

  • Avoid cutting structural beams or columns
  • Maintain uniform groove depth
  • Keep grooves large enough for conduit installation

This step prepares the wall for concealed conduit placement.

Step 4: Install Electrical Boxes

Switch boxes, socket boxes, and junction boxes are fixed into the wall openings.

Installation Guidelines

  • Ensure proper alignment using a spirit level
  • Fix boxes firmly with cement or screws
  • Leave enough space for wire connections

Correct box installation improves switch and socket positioning.

Step 5: Lay the Conduits

Now the conduits are installed inside the wall grooves.

Types of Conduits Commonly Used

  • PVC Conduits: PVC conduits are lightweight, corrosion-resistant, and commonly used in residential buildings.
  • Metallic Conduits: Metal conduits provide stronger mechanical protection and are preferred in industrial installations.

Step 6: Pull Electrical Wires Through the Conduits

Once the conduits are secured, electrical wires are pulled through using fish tape.

Common Wire Types

  • Phase wire
  • Neutral wire
  • Ground wire

Important Wiring Tips

  • Follow standard wire color codes
  • Separate lighting and power circuits
  • Avoid overfilling conduits
  • Use wires with proper load capacity

Step 7: Make Electrical Connections

After pulling the wires, connect them to switches, sockets, fixtures, and the distribution board.

Connection Tips

  • Tighten all terminal connections properly
  • Use insulated connectors
  • Avoid loose joints
  • Label circuits if needed

Poor electrical connections can cause overheating and power failures.

Step 8: Test the Wiring System

Before covering the walls, test the entire wiring system.

Common Electrical Tests

  • Continuity test
  • Insulation resistance test
  • Grounding test
  • Voltage verification

Testing helps identify faults before final wall finishing.

Step 9: Cover the Wall Grooves

After successful testing, fill the wall grooves using plaster or cement.

Final Finishing Process

  • Smooth the wall surface
  • Allow proper drying
  • Prepare for painting or finishing

This step completely hides the conduit system inside the walls.
