A brief bit of googling:
"One of the most misunderstood and confused concept is difference between
Bonding,
Grounding and
Earthing. Bonding is more clear word compare to Grounding and Earthing, but there is a micro difference between Grounding and Earhing.
Earthing and Grounding are actually different terms for expressing the same concept.
Ground or earth in a mains electrical wiring system is a conductor that provides a
low impedance path to the earth to prevent hazardous voltages from appearing on equipment. Earthing is more commonly used in Britain, European and most of the commonwealth countries standards (
IEC, IS), while Grounding is the word used in North American standards"
