According to 250.20 (B) of the 2024 NEC alternating-current (AC) systems of 50 volts to 1000 volts must be grounded which means referenced to earth. This is accomplished through a properly installed grounding electrode system.

My understanding is that "ground" means that the node can and should be tied to the earth. "Common" implies an arbitrary voltage reference with no connotation about its voltage relative to earth. One might have multiple commons in a schematic, but earth is earth.
WebElectrical Grounding is defined as the process of transferring the immediate discharge of electricity directly to the Earth with the help of a low-resistance wire. Electrical grounding was invented as a safety system to help prevent people and equipment from accidentally coming in contact with electrical hazards.
