Grounding and Bonding Toolbox
Bonding is simply a matter of taking all of the electrical and metallic masses in a facility and connecting them with conductors, bringing them to the same electrical potential. The primary reason for bonding is personnel safety, so someone touching two pieces of equipment at the same time does not receive a shock by becoming the path of equalization if they happen to be at different potentials.
Grounding is a matter of bringing the bonded equipment mass to the potential of the surface of the earth which it occupies. The purpose of grounding and bonding is to protect you from the danger of electric shock. Grounding and bonding achieves this by ensuring that when an electric fault occurs, the potential of the metal parts of enclosures will be maintained at a safe value with respect to earth and/or the fault will cause the system to be disconnected by a protective device.
