The answer becomes clearer when we look at the three roles wiring must fulfill: hot, neutral, and ground. These three components work in tandem to distribute power throughout your home, as well as help maintain electrical safety.
What are the three wires in a household electrical connection?
- The electric power line enters our house through three wires- namely the live wire, the neutral wire and the earth wire.
- To avoid confusion we follow a colour code for insulating these wires.
- The red wire is the live wire, and the black wire is neutral.
- The earth wire is given green plastic insulation.
What do the 3 wires do?
The plug contains three wires – the live, neutral and earth wires. In a plug, the live wire (brown) and the neutral wire (blue) are the two wires that form the complete circuit with a household appliance.
Live, neutral and earth mains wires.

What is 22 gauge wire used for?
Here at SparkFun, we typically use 22 AWG wire for prototyping and breadboarding. When using a breadboard or PCB, solid core is perfect because it fits nicely into the holes. For other prototyping/building involving soldering, the stranded core is #1, just be sure not to let too much current run through a single wire.
Which wire is used for wiring nowadays?
For household wiring, the material is either copper or aluminium (or copper-sheathed aluminium), although aluminum is not really used anymore. It can be stranded wire or solid metal conductor and in most cases, it is insulated, using a non conductive plastic coating.
