Q. In a larger remodel, a bathroom and bedroom are added together and the existing panel will not accept an arc-fault breaker. The electrician installs a panel to accept an arc-fault breaker as
supplementary protection. Can this circuit be added to the permit without taking out a feeder permit as well as new circuit? 210.12
A Yes. The question specified that this was one circuit with supplementary overcurrent protection, to accommodate an AFCI. Be advised that a permit may be modified anytime until final inspection.
See OAR 918-309-0000(2). (May 1, 2003 Tri-County Code Forum; approved by state electrical code chief for statewide application)
Q. Article 210.12 (B) requires all outlets in bedrooms to be on an arc-fault circuit, including switches that operate devices out of bedroom area (Christmas lighting outlets and security lights
on exterior). Most of the time, these switches are in the master bedroom or master bedroom closet. If closet is off the master bath, and the master bath is separated from the master bedroom by a
door, are they required to be on an -arec-fault circuit? (The switches are not in the bedroom.)
A. Refer to Article 210.12 (B). If the outlet is installed in the bedroom or on the bedroom branch circuit, AFCI protection is required.
