Electrical Switch Installation Process

Electrical engineering work usually follows the demolition phase. Before starting, customers need to finalize the positioning of all furnishings.

The procedure is as follows:
  1. Positioning: If the project has hired a designer, they will provide a layout for the contractor (If no designer is involved, the contractor will work with the customer directly on-site to determine placements).

  2. Drilling: Drilled holes should typically be both horizontal and vertical.

  3. Concealed Wiring Installation: This involves hidden conduits, so the pipes and junction boxes are concealed within the walls.

  4. Wire Installation.

  5. Filling Wire Holes: After the wiring has been laid, the holes are patched with plaster (Take photos to document the locations for future reference or repairs).

  6. Painting or Tiling.

  7. Faceplate Installation: Installation of switches and sockets. They generally come as single or double sockets and have ratings like 13A/20A. The height should be consistent throughout the installation. Typically, switches are installed at 1300mm from the floor, while floor sockets are placed 200mm off the ground.
