   What is a 3 core cable?

   • What is a 3-Core Cable? A 3-core cable consists of three conductive wires, typically copper, each insulated by its own layer and then enclosed together within an additional outer insulation. The three cores typically represent the live, neutral, and earth wires, making these cables ideal for grounded electrical applications.

   The Cable sizes for domestic lighting circuits is usually 1mm or 1.5mm twin and earth cable (aka two core and earth). In most cases 1mm should be fine but depends on how many lights are on the circuit and how long the cable run is. If quite a few are required or the cable run is over a long distance, then 1.5mm cable should be used to cope with sup...

   As we have established above, how you identify electrical cable size is through the size of wire it houses e.g. 1.5mm cable houses 1.5mm wire. In most instances, the size of cable should be printed on the sheath, but if not you will need to calculate the diameter of the wire to determine its size, which means working out the area of a circle e.g. t...

   Different cables and flexes are used for different jobs because they are thicker and can carry more current and have more, or less resistance. Resistance can be thought of as electrical friction and the wires in the cable or flex will absorb some of the energy in the current, allowing a little less to reach the target than was sent. High energy use...
