† Unless otherwise specifically permitted elsewhere in this Code, the overcurrent protection for conductor types marked with an
obelisk (†) shall not exceed 15 amperes for No. 14, 20 amperes for No. 12, and 30 amperes for No. 10 copper; or 15 amperes for
No. 12 and 25 amperes for No. 10 aluminum and copper-clad aluminum after any correction factors for ambient temperature and
number of conductors have been applied.
