210.23(A)(1) Loads Permitted for 10-Ampere Branch Circuits
A 10-ampere branch circuit shall be permitted to supply one or more of the following:
1. Lighting outlets,
2. Dwelling unit exhaust fans on bathroom or laundry room lighting circuits,
3. A gas fireplace unit supplied by an individual branch circuit

210.23(A)(2) Loads Not Permitted for 10-Ampere Branch Circuits
A 10-ampere branch circuit shall not supply any of the following:
1. Receptacle outlets
2. Fixed appliances
3. except as permitted for individual branch circuits
4. Garage door openers
5. Laundry equipment

210.23(B) 15- And 20-Ampere Branch Circuits
A 15- or 20-ampere branch circuit shall be permitted to supply lighting outlets, lighting units, or other utilization equipment, or any combination of them, and shall comply with 210.23(B)(1) and (B)(2).
Exception: The small-appliance branch circuits, laundry branch circuits, and bathroom branch circuits required in a dwelling unit(s) by 210.11(C)(1), (C)(2), and (C)(3) shall supply only the receptacle outlets specified in that section.<\/span><\/em>

210.23(B)(1) Cord-and-Plug-Connected Equipment Not Fastened in Place
The rating of any one cord-and-plug-connected utilization equipment not fastened in place shall not exceed 80 percent of the branch-circuit ampere rating.

210.23(B)(2) Utilization Equipment Fastened in Place
The total rating of utilization equipment fastened in place, other than luminaires, shall not exceed 50 percent of the branch-circuit ampere rating where lighting units, cord-and-plug-connected utilization equipment not fastened in place, or both, are also supplied.

210.23(C) 30-Ampere Branch Circuits
A 30-ampere branch circuit shall be permitted to supply fixed lighting units with heavy-duty lampholders in other than a dwelling unit(s) or utilization equipment in any occupancy. The rating of any one cord-and-plug-connected utilization equipment shall not exceed 80 percent of the branch-circuit ampere rating.

210.23(D) 40- And 50-Ampere Branch Circuits
A 40- or 50-ampere branch circuit shall be permitted to supply cooking appliances that are fastened in place in any occupancy. In other than dwelling units, such circuits shall be permitted to supply fixed lighting units with heavy-duty lampholders, infrared heating units, or other utilization equipment.

210.23(E) Branch Circuits Larger Than 50 Amperes
