Grounding
Grounding and bonding and the difference between the two.
Grounding (or earthing) is the deliberate or accidental connection of a person or object to electrical earth (virtually zero volts).
Grounding and bonding are often used together but they are different so its best to understand the difference.
Bonding is a deliberate joining of conductive materials to ensure a consistent voltage.
Bonding to electrical earth is used extensively to ensure that all conductors (person, surface and product) are at the same electrical potential. When all conductors are at the same potential no discharge can occur. Theoretically all conductors could be at a 1,000 Volts and no discharge would occur but since earth is readily available it is used in virtually all cases.
Note: Grounding and bonding only applies to conductors.
