What wire size is required for a branch circuit with 10 outlets and a 15 amp breaker?

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.

What is the minnimum size equipment grounding conductor required by the NEC for a branch-circuit protected by a 50-ampere rated circuit breaker?
The minimum size equipment grounding conductor required by the NEC for a branch circuit protected by a 50-ampere rated circuit breaker is 10 AWG copper or 8 AWG aluminum.
How many oulets in a 15 amp breaker circuit?
Branch circuit loading In Canada the CEC states that there shall be not more than 12 outlets on any 2-wire branch circuit. These outlets shall be considered to be rated at not less than 1 amp per outletWhere the connected load is known, the number of outlets shall be permitted to exceed 12, provided that the load current does not exceed 80% of the rating of the over current device protecting the circuit. For example on a 15 amp breaker, 15 x 80% = 12 amps, hence the standard of 12 outlets on any 2-wire branch circuit.On a 20 amp breaker, 20 x 80% = 16 amps. So from a 20 amp breaker this allows 16 outlets on a 2-wire branch circuit as long as the outlets are not considered to be rated at less than 1 amp per outlet.The definition of an outlet is a point in the wiring installation at which current is taken to supply utilisation equipment. What this means is that if a light switch and a fixture outlet were on the same 2-wire branch circuit they would be subtracted from the maximum count of 12 receptacle outlets on the circuit which would leave 10.If the light fixture draws 3 amps plus the switch outlet, then the total circuit outlet count would be reduced to 8 receptacle outlets (12 – 3 – 1 = 8).On a standard specification home most electricians will wire one circuit per room, the outlet count usually never reaches the maximum of 12 outlets.
How many lighting outlets are permitted on a branch circuit?
The National Electrical Code typically allows a maximum of 12 lighting outlets on a 15-amp branch circuit and 16 lighting outlets on a 20-amp branch circuit. However, these numbers can vary based on local code requirements, so it's important to check with your local authority having jurisdiction.
What causes the main breaker to trip from a fault current from a twenty amp branch circuit?
A fault current on a twenty amp branch circuit can cause the main breaker to trip due to the higher-than-normal flow of electricity, which exceeds the circuit's capacity. This could be caused by a short circuit (abnormal connection between conductors) or a ground fault (unintended connection between a conductor and ground). The main breaker detects this overload and trips to prevent overheating and potential fire hazards.
What is the purpose of a branch circuit?
To supply power to all electrical devices in a house, apartment, condominium, etc. A branch circuit is connected to the circuit breaker panel which is usually found in a closet or a cupboard
Is a circuit breaker required on every branch circuit?
yes

How are Branch circuit protected?
Branch circuits are protected by the circuit breaker found in the electrical panel. Each circuit should have its one breaker. The breaker should be rated to protect the insulation of the wire, so you can determine the breaker size based on the circuit conductor size Example #14-2 should be protected by a 15 amp breaker

What type of circuit breaker is required for a 240 v branch circuit?
the circuit breaker used will be miniature circuit breaker(MCB) maily used in homes.Answer for USA, Canada and countries running a 60 Hertz supply service.A two pole circuit breaker is used for a load of 240 volts. It is sized, according to the load amps of the device, to protect the wires that supply the load current.
How many lighting outlets are permitted on a branch circuit?

What is the difference between a run and a circuit?
run in a electrical system means a wiring & conduit runs coming from Panel Board Circuit Breaker to its branch circuit loads in a circuit. while circuit is a designated number of branch breaker in a panel board where power load was individual connected.
What are the main parts of a household circuit?
One main part of any household branch circuit is its circuit breaker. It is designed to protect the electrical circuit from damage caused by current overloads or short circuits. It is designed to disconnect the electrical flow within a few milliseconds if it detects certain electrical faults. Then, to be able to provide power to the appliances and lights in the house, there must be fixed outlets and socket outlets supplied by the various branch circuits. Nothing can be provided with electrical power unless there is a main breaker panel to contain all the separate circuit breakers and also to provide the house with a main power on-off switch.
