A power circuit uses a cable having three different wires.
To which wire should the switch and fuse be connected ?

Explanation

To determine to which wire the switch and fuse should be connected in a power circuit with three different wires, we can follow these steps:

### Step 1: Identify the Wires
In a typical power circuit, there are usually three types of wires:
- **Live Wire (Phase Wire)**: This wire carries the current to the load.
- **Neutral Wire**: This wire carries the current away from the load and completes the circuit.
- **Earth Wire (Ground Wire)**: This wire is used for safety purposes and prevents electric shock by directing any fault current to the ground.
