Branch Circuits & FeedersCâu 18 / 120
In a dwelling unit, 125-volt receptacles installed within what distance of the outside edge of a sink require GFCI protection?
a.5 feet
b.3 feet
c.6 feet
d.10 feet
Giải thích
The measurement is 6 feet from the outside edge of the sink, taken along the shortest path a cord would follow without piercing a wall or partition. The 3-foot dimension belongs to other rules such as service conductor clearance from openable windows, and 5 or 10 feet are not used for the sink measurement.
