- 3-core cables --> three wires inside them each with a core of copper and a plastic coating
- Live wire (brown) --> alternates between positive and negative charge
- Neutral wire (blue) --> 0 V
- Earth wire (green and yellow) --> protects wiring and safety, prevents wire and shocks. It is attached to the metal casing and if something goes wrong, it touches it and it carries the electricity to the earth
Wiring:
1. right coloured wire connected to each pin and firmly screwed in
2. no bare wires showing inside plug
3. cable grip fastened tightly over cable outer layers
4. thicker cables --> less resistance so they carry more current
Features:
1. metal parts --> copper or brass because they're good conductors
2. case, cable grip and cable insulation --> rubber or plastic because they're flexible and good insulators
^^^ keeps the electricity flowing where it should
