Which protection is required for 120-volt, 15- and 20-ampere branch circuits supplying receptacle outlets in dwelling bedrooms?
a.GFCI only
b.AFCI
c.Surge only
d.None
Explanation
Section 210.12(A) requires arc-fault circuit-interrupter (AFCI) protection for 120-V, 15- and 20-A branch circuits supplying outlets in dwelling bedrooms and many other living areas. AFCI protects against arcing faults that can start fires. GFCI addresses shock, not arcing; surge and 'none' do not meet the rule.
