Whatever electrical application you’re about to embark upon, it’s important that you understand what types of wire or cable you’ll be using. A very popular choice for various uses is the 3 core cable. These are cables that include three separate conductors, for three different purposes of transporting electrical power.
For instance, if you choose to use a 1.5mm 3 core flex cable, it will have three individual wires inside the main cable sheathe. One of those wires is used for live power, the other is for neutral and the third conductor in the 3 core cable is for groud (or earth) applications.
To understand what this means for electrical wiring projects, it may help to view the above information in perspective of other types of wires. Unlike the 3 core wire, a 2-core cable has one less conductor. Its components include just two conductors. So, while a 10mm 3 core armoured cable will have live, neutral and earth (or ground), a corresponding 2-core version of this same cable does not have the ground conductor. It only comes with live and neutral conductors.
