β 10y agoFor a 12-gauge wire, typically a 20 amp breaker is used for general household wiring. However, always refer to local electrical codes and consult with a licensed electrician for specific requirements based on the application and load.
Depends on the wire size used in the circuit. If you use AWG # 14 wire you must use a 15 amp breaker. If it is wired with AWG # 12 wire then you use a 20 amp breaker. If a AWG # 10 wire is used then a 30 amp breaker is required. The breaker protects the wiring from overheating so you must use the proper size breaker for the wire used.
The breaker size for a TNIA-10 wire depends on the maximum current carrying capacity of the wire, which is typically indicated on the wire's packaging or in its specifications sheet. You should select a breaker that is rated slightly higher than the wire's maximum current capacity to ensure safety and avoid overloading the wire. It is recommended to consult with a qualified electrician for specific guidance on breaker sizing for your installation.
You can use a 20-amp single pole breaker for 12-2 wire. This is the standard size breaker for 12-gauge wire in residential applications.
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.
No, it is not safe to use a 40-amp breaker on a 220V welder with 12-3 wire. The wire size should match the breaker size to prevent overheating and potential fire hazards. In this case, a 30-amp breaker should be used with 12-3 wire for a 220V welder.

The size breaker you use is determined by the size wire used in the circuit. If you use AWG #12/2 wire then use a 20 amp breaker. If you use AWG # 14/2 then use a 15 amp breaker.
A typical home entertainment system may require a 15-amp circuit breaker. It's important to ensure the total power consumption of all components does not exceed the amp rating to prevent overloading the circuit. It's recommended to consult an electrician for proper sizing and installation.
Use 15 amp breaker with 14 gage wire or 20 amp breaker with 12 gage wire. Either way will work just fine.
You can use a 20-amp single pole breaker for 12-2 wire. This is the standard size breaker for 12-gauge wire in residential applications.
For typical residential house wiring 12 AWG wire is required for a 20 Amp breaker. If you change out the breaker for a 25 A breaker you would have to rewire the circuit with 10 AWG. In that case you could up the breaker to 30 Amps. All outlets and switches should be rated at the same voltage and current as the breaker.
A #12 aluminium conductor with an insulation factor of 75 or 90 degrees C is rated at 15 amp. Therefore the largest size breaker to protect that wire will be a breaker rated at 15 amps.
A 1500 watt bathroom exhaust fan heater should be connected to a 15 amp breaker to ensure proper protection against overloads. This is calculated by dividing the wattage (1500 watts) by the voltage (typically 120 volts for residential circuits) to determine the amperage (12.5 amps in this case, which you would round up to the nearest standard breaker size).
Look on the heater and see what amps it is pulling. That will determine the wire size and breaker size. It must be on a dedicated circuit. 15 amps = AWG # 14 wire with 15 amp breaker 20 amps = AWG # 12 wire with 20 amp breaker 30 amps = AWG # 10 wire with 30 amp breaker 40 amps = AWG # 8 wire with 40 amp breaker
It is not the number of bulbs that you worry about. It is the wire size that is your concern. If the circuit is wired with AWG 12/2 wire then use a 20 amp breaker. If it is wired with a AWG 14/2 wire then use a 15 amp breaker. You are protecting the wiring with the correct size breaker.
Use a 20 amp fuse or breaker.
