When installing a circuit breaker, you size the breaker based on the wire size. The breaker should be matched to the ampacity of the wire to ensure proper protection against overloads and short circuits. The device being controlled by the breaker is not a determining factor in sizing the breaker.
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.
It is not recommended to connect a 14 gauge wire to a 12 gauge wire on a 20 amp breaker, as this can create a safety hazard. It's important to match the wire gauge to the circuit breaker rating to prevent overheating and potential fire hazards. It would be best to run a continuous 12 gauge wire for this circuit.
With a 15 A breaker you need 14 Gauge wire. Normally you would only put 8 outlets on a 15 A circuit. If you have the option you shoudl consider a 20 A circuit, use 20A receptacles and 12 gauge wire. Comment: The question was on a homeowners electrical exam. My answer was also 14 gauge however, the tester said the answer was 12 ga. I thought maybe there was something special about the 10 outlets. For example, 10x180 VA per outlet/120V = 15 A which is right at the limit for 14 ga but would be 75% for the 12 ga wire.
I think you mean either what is the correct size or minimum wire size needed when a branch circuit is protected by a 20 A breaker. The size is 12 American Wire gauge (AWG). 14 AWG is used for 15 A circuit and 10 AWG for a 30 A breaker. The lower the gauge the larger the cross-section of the wire.
Normally it is a 20 amp using AWG 12/2 gauge wire. But it really depends on what size wire is on that circuit. If it is white AWG 14 gauge then use a 15 amp breaker. If it is yellow AWG 12 gauge then use a 20 amp breaker.

The recommended wire size for a 20 amp breaker is typically 12-gauge wire.
A 30-amp circuit breaker is typically suitable for 10-gauge wire.
Use AWG # 6 wire.
For a 30 amp breaker, you will need a wire that is at least 10 gauge in size.
The recommended wire size for a 30 amp circuit is typically 10 gauge wire.
The recommended wire size for a 40 amp breaker is typically 8 AWG (American Wire Gauge).
The recommended wire size for a 35 amp breaker is typically 8 AWG (American Wire Gauge) for copper wire.
Yes but there are two stipulations, one that the join or splice must be made in a junction box that is accessible and has a removable cover and the second stipulation is that the breaker that is supplying the power can not be larger that the smallest conductor. In this case no breaker larger that a 20 amp breaker as #12 wire is only rated at 20 amps..
