If you had to ask this question here you need to learn more about your local wiring code re all the items you must use for a new household AC power range circuit.
Serious home fires can result from incorrectly installed new circuits.
So that the new installation is safe and legal - and complies with the terms of your home insurance policy - you must use the correct type and size of cable, the correct type of circuit breaker and the correct type of wall outlet.
From the local wiring code, a licensed electrician will know which size of wire to use because the answer depends both on the current to be carried (amps) and on the length of the run from the breakers on the main supply panel to the place where the outlet for the kitchen range is to be fixed.
For your own personal safety -- as well as your family and anyone else who may use the new range circuit in the future (such as if you sell your home) -- the best advice anyone can give you is call a licensed electrican to do the job. He will be able to advise you about the right wire size for the length of run, the types of breakers (main panel and GFCI), the outlet and anything else which may be necessary for your new range circuit to comply with the wiring codes in your locality (town/state), and he would install them safely for you.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

For a 30 amp circuit, it is recommended to use a wire size of at least 10 gauge copper wire. This wire size is capable of safely carrying 30 amps of current and will help prevent overheating or voltage drops in the circuit. Be sure to consult local electrical codes and regulations before proceeding with the installation.
As a rule of thumb, for circuits of shorter length, 10AWG (copper wire) or 8 AWG (aluminum wire) are matched to 110 volt, single phase, with a load of 30A.
**Bear in mind that the wire gauge required by code may be different in some locations; to ensure you use the correct gauge, consult your local building inspector - the electric company will have contact details.
Voltage Drop.
When a run of wire exceeds a certain distance, the voltage drop is important. Usually, it's not a problem in circuits within a house, but may become an issue when the wire runs to an outbuilding, well, etc.
Excessive voltage drop can cause loss of efficiency in operation of lights, motors, and appliances. To avoid this, choose a wire gauge that minimizes the voltage drop.
The table below gives gauges that are true for copper wire carrying 110 volt, single phase, with a load of 30A, for a maximum of 3% voltage drop.
Length = Gauge
25 ft = 10 AWG
50 ft = 8 AWG
100 ft = 6 AWG
150 ft = 4 AWG
200 ft = 3 AWG
The table below gives gauges that are true for wire carrying 220 volt, single phase, with a load of 30A, for a maximum of 3% voltage drop:
Length = Gauge
25 ft = 10 AWG (copper) or 8 AWG (aluminum)
50 ft = 10 AWG (copper) or 8 AWG (aluminum)
100 ft = 8 AWG (copper) or 6 AWG (aluminum)
150 ft = 6 AWG (copper) or 4 AWG (aluminum)
200 ft = 6 AWG (copper) or 4 AWG (aluminum)

The wire size for a 30 amp breaker is a #10 copper conductor which is rated at 30 amps. The only time a larger size wire will be used on a 30 amp breaker is when the distance to the load is a specific distance away from the distribution supply. The larger size wire is used to over come voltage drop.

What size ground wire is need for a 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.
Have 30 amp double pole need 15 amp 120v?
You can use a 15 amp single pole breaker to convert your 30 amp double pole breaker to 15 amp 120v. Simply replace the 30 amp breaker with the 15 amp breaker in the circuit breaker panel. Make sure to match the wire size in the circuit with the appropriate amperage rating of the new breaker.
What wire size needed for 120 volt 3000 watt load?
AWG # 10 wire on 30 amp circuit.
Can you have a 120v circuit on a 30 amp breaker?
No, electrical code typically requires that circuits be protected by a breaker that matches the wire size. A 30 amp breaker is typically used for circuits with larger wire sizes. For a 120V circuit, a 20 amp breaker is more suitable with appropriate wire size.
Can a 240v 50amp circuit be changed to a 120v 30amp circuit?
No, it is not recommended to downgrade a 240V 50A circuit to a 120V 30A circuit. The wiring and breaker size must match the voltage and amperage requirements of the appliances being used. It is important to consult with a licensed electrician for any modifications to ensure safety and compliance with electrical codes.
How can you push 30 amp breaker to 50 amp?
Not if it's functioning properly. The purpose of a circuit breaker is to shut off power if the circuit exceeds the rated power capacity of the wires. Don't plan to exceed the 30 Amp capacity of your house wiring; the results will be destructive.
What are the standard size circuit breaker amperages?
In North America the standard sizes for breakers are 15, 20, 30, and 40 amps. The 15 amp size breaker is used in general circuit wiring. The 20 amp size breaker is used for dedicated appliance receptacles, hot water tank and baseboard heating. The 30 amp size breaker is used for a clothes dryer. The 40 amp size breaker is used for the electric range.
How do you turn a 30 amp circuit into a 15 amp cicuit?
Replace the 30 Amp Breaker with a 15 Amp breaker.
Is a 2 pole 30 amp circuit breaker equivalent to 30 amp?
Yes.
What size ground wire is need for a 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.
Have 30 amp double pole need 15 amp 120v?
You can use a 15 amp single pole breaker to convert your 30 amp double pole breaker to 15 amp 120v. Simply replace the 30 amp breaker with the 15 amp breaker in the circuit breaker panel. Make sure to match the wire size in the circuit with the appropriate amperage rating of the new breaker.
Can 600v wire works 30 amp fuse?
What size is the wire? AWG 10, 600V is rated for 30 amps. Any AWG less than 6 would also be ok for a 30 amp circuit....
What wire size needed for 120 volt 3000 watt load?
AWG # 10 wire on 30 amp circuit.
What size amp circuit breaker should be used for a gas dryer?
Typical residential electric dryers are on 30 amp circuits, which means 10 gage copper wire. The circuit breaker should match the dryer cord rating, generally 30 amps.
Can you have a 120v circuit on a 30 amp breaker?
No, electrical code typically requires that circuits be protected by a breaker that matches the wire size. A 30 amp breaker is typically used for circuits with larger wire sizes. For a 120V circuit, a 20 amp breaker is more suitable with appropriate wire size.
Can a 240v 50amp circuit be changed to a 120v 30amp circuit?
No, it is not recommended to downgrade a 240V 50A circuit to a 120V 30A circuit. The wiring and breaker size must match the voltage and amperage requirements of the appliances being used. It is important to consult with a licensed electrician for any modifications to ensure safety and compliance with electrical codes.
How do you replace a 15 amp circuit to a 25 amp circuit?
You have to rewire the circuit completely with 10 AWG wire and replace all outlets and switches with devices rated at 25 Amps. Note 25 Amp breaker is an unusual size. 10 AWG will go up to 30 amps, and that would be the way to go.
