It depends upon the distance, but typically a short to medium run (0-50 feet) of 12 gauge can carry 20 amps safely. There are charts that list the gauge of wire and the length of runs that can carry amperages safely. For instance, a 12 gauge wire run 150 feet can only carry 15 amps safely instead of 20. The longer the run, you need to drop a gauge as a general rule.
In the United States and according to the NEC, 12 gauge COPPER wire cannot be placed on any breaker larger than 20 amps. There are exceptions to this regarding motors, but I'm guessing this isn't a motor question. Beyond motors, there are no exceptions to this rule.
Voltage isn't a consideration in most cases because if you just go to a store and ask for wire, what they usually sell you is THHN insulated wire that is rated 600 volts. So long as the voltage rating is at or above any voltage contained in the same conduit or wireway, it is acceptable.
Typically 20 amps in residential and most commercial applications.
A #14 copper conductor with a insulation factor of 60,75 or 90 degrees C is rated at 15 amps.

What size hot wire do you need for a 1900 watt amp?
A 12 gauge wire can support a load of approximately 2200 watts.
Is it safe to use 10 gauge wire on a 20 amp breaker for a microwave?
No, 10 gauge wire requires the use of a 30 amp breaker. A 20 amp breaker is only used on 12 gauge wire.
Can you use 14-3 wire on a 20amp breaker?
No. A 20 amp breaker needs 12 gauge wire.
What is the wire size required for 1800 watts for lamps?
14 gauge will handle it with a 15 amp breaker. If you use 12 gauge use a 20 amp breaker.
What size circuit breaker for GFCI circuit in a normal size bath?
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.
What size hot wire do you need for a 1900 watt amp?
A 12 gauge wire can support a load of approximately 2200 watts.
What is the amp rating of NM wire?
The amp rating of NM (Non-Metallic) wire varies depending on the gauge of the wire. For example, a 14-gauge NM wire typically has an amp rating of 15 amps, while a 12-gauge NM wire has an amp rating of 20 amps. It is important to consult local building codes and regulations to determine the appropriate wire gauge and amp rating for specific applications.
Can you go from a 14 gauge to 12 gauge wire?
it is not recommended because the 14 gauge wire is not capable of carrying the same amount of load as the 12 gauge wire which could result in a fire.
If your fuse box supports 20 amp fuses can you replace one current 15 amp fuse with a 20 amp fuse?
The purpose of a fuse it to protect the wire that goes to the load. A 15 amp fuse protects a #14 gauge wire. A 20 amp fuse protects a #12 gauge wire. To answer your question if the wire size is #12 coming from the 15 amp fuse now then it can be upped to 20 amp fuse. If it isn't then you are taking the risk of overloading the #14 wire with a 20 amp fuse. This can lead to insulation failure of the #14 wire, overheating with the possible outcome of a fire breaking out somewhere in the circuit.
What gauge wire is used on a 20 amp breaker?
AWG 12.
What size wire in a 40 amp 12 volt circuit?
Use 8 gauge wire.
Is it safe to use 10 gauge wire on a 20 amp breaker for a microwave?
No, 10 gauge wire requires the use of a 30 amp breaker. A 20 amp breaker is only used on 12 gauge wire.
What gauge wire for 30 amp at 12 ft?
A #10 copper wire with an insulation rated at 90 degree C has a rating of 30 amps. Over the distance of 12 feet, there is no appreciable voltage drop that will effect the load.
What is stronger holding current load a 12 gauge wire or a 14 gauge wire?
The lower gauge number is always a thicker wire which can carry more current.
What is a wire gauge and what is it's use?
wire gauge is used to determine the size of the wire to be installed based on the amperage draw of whatever is being hooked up on the receiving end. ie 14 gauge is for a 15 amp circuit, 12 gauge is for a 20 amp circuit, 10 gauge 30 amp etc. to get specific amp draw ratings on a particular gauge of wire look at a current National Electric code book or ugly book.
Can 13 gauge wire be connected to a 20 amp breaker?
No, it is not recommended to connect 13 gauge wire to a 20 amp breaker. The wire gauge should match the amp rating of the breaker to prevent overheating and potential fire hazards. In this case, a 20 amp breaker should be used with at least 12 gauge wire.
Could 12 gauge wire is used on a 20 amp circuit at 120V?
Yes.
