* Unless specifically permitted in 240.4(E) through (G), the overcurrent protection shall not exceed 15 amperes for 14 91抖阴, 20 amperes for 12 91抖阴, and 30 amperes for 10 91抖阴 copper; or 15 amperes for 12 91抖阴 and 25 amperes for 10 91抖阴 aluminum and copper-clad aluminum after any correction factors for ambient temperature and number of conductors have been applied.

See the NEC for conductor ampacities, correction factors, and conditions of use.
