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.
What else can I help you with?
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 wire should be used for outlets?
For outlets, it is recommended to use 12-gauge wire for 20-amp circuits and 14-gauge wire for 15-amp circuits.
What is the amp rating of NM wire?
The ampacity or amp rating of all wire is rated by the size of the wire. NM (non-metallic sheathing) wire is no different. In household wiring 14 gauge wire must go on a 15 amp breaker/ 12 gauge goes on a 20 A and 10 gauge goes on a 30 Amp.
What is the recommended wire size for a 20 amp breaker?
The recommended wire size for a 20 amp breaker is typically 12-gauge wire.
What is the appropriate wire size for a 20 amp circuit?
The appropriate wire size for a 20 amp circuit is typically 12-gauge wire.
What is the recommended wire size for a 20 amp circuit?
The recommended wire size for a 20 amp circuit is typically 12-gauge wire.
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.
What gauge wire is used on a 20 amp breaker?
AWG 12.
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 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 is the recommended wire size for a 220v 20 amp circuit?
The recommended wire size for a 220v 20 amp circuit is typically 12-gauge wire.
