![]() If you’re installing a circuit breaker in your home, it’s crucial to use the right size of wire. The minimum wire size for a 30 amp circuit is 10 gauge, while thicker wire is recommended for more stable current supply. ![]() The size of the wire you use to run a 30 amp breaker depends on the load it is carrying. What size wire do I need to run a 30 amp breaker? Using wire smaller than eight gauge could cause a circuit overload, which is dangerous and may cause property damage. When using wire for your circuit, you should follow the 80 percent rule: any load you put on it must be at least 80 percent of the breaker’s amp rating. However, it shouldn’t be used with wire smaller than ten gauge. You can use thicker wire, but that’s more expensive and harder to install through conduits.Ī thirty amp breaker can handle eight-gauge wire. This limit can cause problems with certain devices, and that’s why it’s important to use the proper wire size for this circuit. However, it is essential to understand that a circuit breaker can only handle 30 amps of current. You should not use smaller wire sizes, as this could result in a fire. A minimum wire size of 10 gauge is adequate for this circuit, and a slightly thicker wire is also safe. Wire size is a very important aspect of a 30-amp circuit, and it varies according to the current load that it is carrying.
