How big of breaker do you use for 115 volt?
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.
What size breaker should be used for a TNIA-10 wire?
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.
How big of a single pole breaker can you put on 12-2 wire?
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.
What is the smallest copper wire size permitted by the national electric code for a 20 amp single phase electrical circuit?
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.
Can you use a 40amp breaker on your 220v welder with 12-3 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.
