Was just replacing the fuse in my hair dryer and shouldn’t there be a wire connected to the earth prong?

1. Not if it’s double-insulated, as I understand it. When there’s no possibility of any electric shock, an earth lead is not required.

2. They don’t need one since hair dryer is usually fully insulated

3. Some devices are [double insulated](https://www.intersafe.co.uk/what-does-class-i-and-class-ii-mean-when-it-comes-to-pat-testing/) (Class 2), so don’t need an earth.

4. Quite often the third pin is now only there to open the shutters on the outlet, no extra earth needed

5. It’s fake anyway, I once looked inside an earth wire and there was no earth in there, just metal.

6. Double isolated, doesn’t need earth

7. What have you done that requires replacing the fuse in your hairdryer?

8. Bojack Fuseman? What is this, a crossover episode?

9. either double insulated or some american products sometimes just get british plugs on them and they dont have grounding so

10. Er – is that a 13A fuse?

    (hard to tell if it’s brown or red – though I’d expect a black 5A fuse.)

11. Double Square= Double Insulated – no need for Earth.

12. Is the top pron plastic? That’s the easiest way to check if something has an earth wire.
    As the others have said, it doesn’t actually need one.

13. Not always, no.
