Joseph - earthing IS the protection. No way around reality.

No, it is not THE protection it is one protection, but not the one in
question.

Earthing or grounding is very important from the standpoint of human
safety from an insulation failure, but we are talking about surge issues and
protection of the equipment from a short, but very high voltage spike. That
voltage is measured between the neutral and the power and does not involve
the "ground" While under normal operation the ground and the neutral are
the same potential, there are times they are different.

Sorry you can't seem to see or understand the difference.
