The minimum wire size for a 30Amp breaker is typically 10 AWG for copper wire and 8 AWG for aluminum wire, according to the National Electrical Code (NEC). This wire size is necessary to safely carry the amount of current without overheating.
AWG # 6 copper or AWG # 4 aluminum
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.
For a 50 amp breaker, you should use a wire size of at least 6 AWG for copper or 4 AWG for aluminum conductors to ensure the wire can handle the current safely and meet safety codes and standards. It is important to consult the local electrical code requirements and consider factors such as wire length and insulation type when selecting the appropriate wire size.
For a 100 amp service, a common feeder wire size would be 2 AWG (American Wire Gauge) copper or 1/0 AWG aluminum. These sizes are appropriate for handling the current capacity needed for a 100 amp electrical service. It is important to consult with a licensed electrician or local building code requirements to ensure the proper wire size for your specific installation.
AWG # 8 copper
AWG # 8 copper.
The minimum wire size for a 30Amp breaker is typically 10 AWG for copper wire and 8 AWG for aluminum wire, according to the National Electrical Code (NEC). This wire size is necessary to safely carry the amount of current without overheating.
AWG # 6 copper or AWG # 4 aluminum
A 100 amp service requires that you use AWG 4 copper wire or AWG 2 aluminum wire.
AWG #4 copper.
Service wire required is AWG # 3/0 copper.
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.
Service entrance wire should be AWG #3 copper.
AWG # 6 copper
For a 50 amp breaker, you should use a wire size of at least 6 AWG for copper or 4 AWG for aluminum conductors to ensure the wire can handle the current safely and meet safety codes and standards. It is important to consult the local electrical code requirements and consider factors such as wire length and insulation type when selecting the appropriate wire size.
Use AWG #1 copper service entrance wire and #4 copper ground wire.
