NOTE

TYPES OF WIRING

Wiring refers to the process of connecting electrical components, devices, and equipment together to form a complete electrical circuit. It involves the installation of conductors, cables, and other electrical materials to transmit electrical power and signals within a building, structure, or system.

Types of Wiring

  1. Conduit Wiring: In conduit wiring, electrical conductors are enclosed within metal or plastic conduits. This type of wiring provides mechanical protection to the conductors and enhances electrical safety by preventing accidental contact and damage. Conduit wiring is commonly used in industrial and commercial buildings where durability and protection against physical damage are priorities.
  2. Surface Wiring: Surface wiring involves running electrical conductors along the surface of walls, ceilings, or floors, typically using conduits, cable trays, or raceways for support and protection.

Surface wiring is often used in situations where concealed wiring is impractical or prohibited, such as in retrofitting existing buildings or temporary installations.

  1. Concealed Wiring: Concealed wiring refers to the installation of electrical conductors inside walls, ceilings, or floors, hidden from view. The conductors are typically routed through concealed channels or cavities within the building structure.

Concealed wiring provides a neat and unobtrusive appearance, making it suitable for residential, commercial, and institutional buildings.

  1. Overhead Wiring: Overhead wiring involves the installation of electrical conductors above ground level, typically supported by poles, towers, or other structures.

This type of wiring is commonly used for power distribution, telecommunications, and outdoor lighting in rural and urban areas.
