Because the metal Copper is a very good conductor - of both electricity and heat - copper wire can be used to carry an electric current in an electric circuit.
The electric current consists of a flow of electrons.
Copper wire itself does not produce electricity. However, when copper wire is part of an electrical circuit and connected to a power source such as a battery or generator, it can transfer electricity by allowing the flow of electrons through it.
The size of the ground wire for a circuit is typically based on the size of the circuit breaker protecting that circuit. For a 200 amp circuit breaker, the recommended ground wire size is 4/0 AWG (American Wire Gauge) copper wire. This wire size helps ensure that the ground wire can safely carry any fault currents that may occur in the electrical system.
For a 100A circuit breaker, you typically need a wire size of #2 AWG (American Wire Gauge) for copper conductors or #1/0 AWG for aluminum conductors. It is important to consult the National Electrical Code (NEC) or a qualified electrician to determine the appropriate wire size for your specific installation.
On a 30 amp circuit, you would use a #10 copper ground. The ground never has to be larger than the ungrounded conductors.

If you mean a bare copper wire, that is the "ground" wire.
The recommended wire size for a 125A electrical circuit is typically 2/0 AWG copper wire.
The recommended wire size for a 200A electrical circuit is typically 2/0 AWG copper wire.
For a 60 amp electrical circuit, the appropriate size of copper wire needed is typically 6 gauge.
The appropriate wire gauge for a 100 amp electrical circuit is typically 3 AWG copper wire.
The recommended wire size for a 125 amp electrical circuit is typically 2/0 AWG copper wire.
The recommended wire size for a 75 amp electrical circuit is typically 6 AWG (American Wire Gauge) for copper wire.
The recommended wire size for a 90 amp electrical circuit is typically 4 AWG (American Wire Gauge) for copper wire.
The ground wire in a circuit is typically colored green or bare copper. It is used to safely direct excess electrical current to the ground to prevent electrical shock or damage to the circuit.
The recommended wire size for a 100A electrical circuit is typically 3 AWG copper or 1 AWG aluminum.
Mainly copper for the wire, pvc for the insulation.
The recommended wire size for a 100 amp electrical circuit is typically 3 AWG copper or 1/0 AWG aluminum.
