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.
In a 200 amp service panel, the ground wire is typically a bare copper wire or green insulated wire. It is connected to the ground bar within the panel. Make sure to consult the manufacturer's instructions or a licensed electrician for guidance specific to your installation.
The ground wire in a two or three conductor #12 cable is a #14 bare ground wire.
For a 200 amp service, you would typically use a 4/0 AWG copper wire for the grounding wire running between the meter box and the service panel. This size is suitable for carrying the necessary current and providing proper grounding protection for the electrical system.
For a 20 amp circuit, a 12-gauge copper ground wire is typically recommended. This wire size can safely handle the current and provide proper grounding for the circuit.
