Where to Find Branch Circuits in the Code
Article 210: Branch Circuits
Article 210 covers the requirements for electrical distribution system conductors. It contains basic rules for defining required branch circuits, the locations of lighting and receptacle outlets and switches, and maximum loading and overcurrent protection for branch circuits, including ground-fault circuit interrupters (GFCIs) and arc-fault circuit interrupters (AFCIs).
I. General Provisions (210.1 Through 210.12)
Part I covers all branch circuits in all occupancies, including multiwire branch circuits, ground-fault circuit interrupters (GFCIs), and arc-fault circuit interrupters (AFCIs).
II. Branch-Circuit Ratings (210.19 Through 210.25)
Part I covers ampacity and overcurrent protection of branch-circuit conductors. Content includes ampere ratings of outlet devices, permissible branch circuits of different ampere ratings, continuous and noncontinuous loads, and common area branch circuits.
III. Required Outlets (210.50 Through 210.70)
Part III covers outlets required for dwelling units; guest rooms or guest suites; show windows; and heating, air-conditioning, and refrigeration equipment, as well as lighting outlets required in dwelling and other units.
