First, talk about the principle of electrical shock. We feel electrical shock when a current go through our body. If there is a different voltage between 2 points in your body so the current will go between them. In your case, let say the equipment is not grounding and touching a voltage, therefore there is a different voltage between your equipment and earth, if 1 part of your body touch your equipment and other part of your body touch the earth so there is a path of current go through these 2 points and you get shock. If the equipment is grounding, there is no different voltage between the equipment and earth therefore no current between these 2 points, no shock.

The main point of grounding equipment is protect electrical shock to people in case your equipment conduit a voltage.

TT, TN are grounding for both electricity system and equipment.

IT is grounding equipment only.
