The size of the main breaker depends on the maximum current rating of the 10 gauge wire and the load it will be powering. Typically, a 10 gauge wire is rated for a maximum current of 30 amps. Therefore, a 30 amp main breaker would be suitable for running 10 gauge wire. However, it is important to consult local electrical codes and consider the specific load requirements before making a final determination.
