        Building Wire

        Building Wire Electrical building wire refers to the cables or wires that transmit electrical power within a building or a structure. These wires are an essential component of an electrical system as they connect electrical devices, outlets, and fixtures to the main power source. Sparky Direct supplies building wires made of copper that are insulated with a protective PVC covering to prevent electrical shock and damage from environmental factors such as moisture and heat.

        Our building wires are designed to meet specific Australian electrical codes and safety standards and come in various sizes, usually measured in gauge or cross-sectional area.

        • 2.5mm², 4mm², 6mm², 10mm² and 16mm²

        How is Building wire rated?

        The size of the wire determines its ampacity, which is the maximum amount of electrical current that the wire can safely carry. Voltage drop must be considered when selecting the correct size building wire. Voltage drop refers to the reduction in voltage that occurs as electrical current flows through a conductor, such as a building wire. This is due to the resistance of the conductor, which converts some of the electrical energy into heat, causing a drop in voltage. The voltage drop increases with the length of the conductor and the amount of current flowing through it.

        In Australia, what do the colours on the building wire represent?

        Building wires are colour-coded to identify their function, with black wires commonly used for neutral, red wires for active, and green-yellow wires for the earth. The correct installation and use of building wires are crucial for the safety and proper functioning of an electrical system. Connecting electrical cables to a power source should be done by a licensed electrician or a qualified electrical contractor. This is because the process involves handling voltages, which can be dangerous and potentially lethal.

        Common building wire accessories:

        • Heat shrink is used when protecting the cable
        • Lugs are used to connect building wire to a busbar
        • Cable connectors are used to join building wire
        • Lube is used to pull cable through conduit easily

        Common tools used to work with building wire.

        A practical use case for Building Wire.

        During the installation of power and light points in a unit block in Sydney, we followed standard procedures. Firstly, all the deep junction boxes were installed into the ceilings and the wall boxes into the walls at the correct height. Rigid conduits were installed, and all the junction and wall boxes were linked to create a robust electrical infrastructure.

        After the concrete floors and ceiling were poured, we removed the lids to the junction boxes and used a pull-through snake to pull the building wire through the conduits. Building wire proved to be a more suitable choice than TPS in this case because it has a thinner diameter, which allowed for more cables to be run in the same conduits.

        Building wire is an electrical wire used for power and lighting installations in the construction industry. Its design includes a robust insulation layer that ensures durability in harsh environmental conditions. The wire's slender diameter makes it a popular choice for installations where multiple cables must be run through conduits.
