Building wiring is one of the most critical stages in the installation of a residential project. Even the smallest mistake at this stage can lead to significant costs, rework, and even serious hazards such as fire. Contrary to popular belief, wiring is not just about installing some wires and conduits; it encompasses a set of standardized consumable materials, each of which plays a crucial role in the safety and final quality of the project.<\/p>\n

In a proper wiring project, the amount of material used depends entirely on the layout, floor area, type of usage, location of switches and outlets, and even the interior architectural style. Therefore, knowing which materials are used in building wiring and their average consumption helps to:<\/p>\n

    \n
  • \n

    Estimate project costs more accurately<\/p>\n<\/li>\n

  • \n

    Prevent over-purchasing or shortages of materials<\/p>\n<\/li>\n

  • \n

    Execute the project according to engineering standards<\/p>\n<\/li>\n

  • \n

    Improve the quality of wiring and reduce future maintenance needs<\/p>\n<\/li>\n

  • \n

    Better manage the budget during renovation or new construction<\/p>\n<\/li>\n<\/ul>\n

    In many buildings, electricians estimate material usage \u201cblindly\u201d based on experience, while for an 80-square-meter house, the exact quantity of wire, conduit, boxes, and junctions can be calculated. Knowing this information is also very important for homeowners, as electrical work is usually priced as a lump sum without details. By knowing the actual material consumption, you can monitor quality and prevent extra costs.<\/p>\n

    In this article, we first introduce all the consumable materials used in building wiring, then examine the standard consumption per square meter, and finally calculate material consumption for 60, 80, 100, and 150-square-meter houses. This is the most precise and comprehensive guide for homeowners, supervising engineers, electricians, and interior designers to make professional and standard material estimates for their projects.<\/p>\n

    2. Complete Classification of Electrical Materials in Buildings<\/h2>\n

    Various materials are used in building wiring, each with a specific role and application. Proper classification not only helps with accurate cost estimation but also makes the execution safer and more standard. The categories are explained in detail below:<\/p>\n

    2.1. Wires and Cables<\/h3>\n

    a) Flexible Wire (Stranded)<\/strong><\/p>\n

      \n
    • \n

      Flexible wires are highly versatile, ideal for complex paths (e.g., inside small ducts, bends, or corrugated conduits).<\/p>\n<\/li>\n

    • \n

      Common sizes for residential wiring: 1\u00d71.5 mm\u00b2 (lighting), 1\u00d72.5 mm\u00b2 (outlets), 1\u00d74 or 1\u00d76 mm\u00b2 (for higher-power circuits such as air conditioning systems).<\/p>\n<\/li>\n

    • \n

      Advantages: good conductivity, easy installation, better adaptability to narrow channels.<\/p>\n<\/li>\n<\/ul>\n

      b) Solid Wire<\/strong><\/p>\n

        \n
      • \n

        Solid wires have a fixed diameter and are used for short, simple routes or areas with few bends.<\/p>\n<\/li>\n

      • \n

        They are an economical choice for low-load circuits that do not require high flexibility.<\/p>\n<\/li>\n<\/ul>\n

        c) Power Cables<\/strong><\/p>\n

          \n
        • \n

          Usually multi-core (e.g., 3\u00d72.5 mm\u00b2, 3\u00d74 mm\u00b2), used for circuits with multiple phases or high current (e.g., air conditioners, pumps, ventilation systems).<\/p>\n<\/li>\n

        • \n

          Power cables must be selected according to insulation quality and conductor capacity to prevent excessive heating in long runs.<\/p>\n<\/li>\n<\/ul>\n

          d) Telephone, Network, and Antenna Cables<\/strong><\/p>\n

            \n
          • \n

            Telephone cable: usually 2\u00d72 or more, for telephony inside the building.<\/p>\n<\/li>\n

          • \n

            Network cable: Cat5e, Cat6, or Cat6a for internal network systems (internet, computers, IP cameras).<\/p>\n<\/li>\n

          • \n

            Antenna cable: usually RG6 or RG59, used for television signal distribution.<\/p>\n<\/li>\n<\/ul>\n

            \n

            2.2. Electrical Conduits and Ducts<\/h3>\n

            Conduits and ducts protect wires and cables from mechanical damage, heat, or construction conditions.<\/p>\n

            a) Heat-Resistant Corrugated Conduit<\/strong><\/p>\n

              \n
            • \n

            • \n

              Common diameters: 13, 16, 20, 25 mm depending on the number of wires inside.<\/p>\n<\/li>\n

            • \n

              \u201cHeat-resistant\u201d indicates higher thermal tolerance, suitable for areas near panels or junction boxes.<\/p>\n<\/li>\n<\/ul>\n

              b) PVC Electrical Conduit<\/strong><\/p>\n

                \n
              • \n
