Q.When installing a single circuit in a newly constructed bedroom, can a minor label be used to set a sub panel with a single 20-amp arc-fault breaker feeding the bedroom?

A. No, the minor labels may not be used for such an installation in new construction. However, in a remodeled bedroom, where the existing panel box is not compatible with AFCI breakers, a small sub panel, limited to 30 amps and two circuits, that will accept an AFCI breaker, can be installed using a minor label.
