Branch Circuits & WiringQuestion 125 of 521
A 125-volt, 20-ampere receptacle installed in the unfinished portion of a dwelling basement used for storage or a work area requires what protection?
a.AFCI only
b.GFCI
c.No protection
d.Isolated ground
Explanation
Section 210.8(A)(5) requires GFCI protection for receptacles in unfinished basement areas not intended as habitable rooms, such as storage and work areas, because of the damp concrete environment. AFCI alone does not provide shock protection; 'no protection' and an isolated ground do not satisfy the rule.
