Or if you plug the Apple power adapter into a power strip with a circuit breaker.

Now, if only grounded cable outside UK plugs was available more than speaking magical white crows...

The EU plugs are all available with earth. The earthed one only at the end of the extension cord to the power brick. Both included in the box from apple.

Please tell me where you're buying, cause I have yet to encounter an earthed plug included with Apple equipment outside of UK. Only two-pole plugs, on the brick, and getting the long cord with ground wire sometimes requires a wait time.
