I have done a lot of electrical work. NEC electrical code article 210.12(A), installing an AFCI breaker is required in all single-phase and 15 to 20 amp circuits with a 120V supply. This rule applies to the area of the kitchen, most rooms of a house, and hallways. Bathrooms are required to have GFCI outlets and AFCI breakers are not required. Also, you can install a GFCI outlet on a circuit with a GFCI breaker. The NEC doesn’t encourage this practice however.
