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.
A #14 wire will do fine for grounding a 20 amp device. That is the size of the ground wire in a 2 conductor # 12 wire building cable.
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.
The ground wire in a two or three conductor #12 cable is a #14 bare ground wire.
AWG # 10 wire on 30 amp circuit.
For a 30 amp circuit, a 10 gauge copper wire is typically recommended for the ground wire. This ensures proper grounding and safety within the electrical system.
For a 100 amp service panel, typically a #8 copper wire or a #6 aluminum wire is recommended for grounding purposes. It's important to follow local electrical codes and regulations when selecting the correct size of the ground wire. It's always a good idea to consult with a licensed electrician for specific guidance based on your individual circumstances.
