Correct answer to question 4004
- A: Yes, laundry area receptacles from 125 through 250 volts are covered
Explanation
The dwelling GFCI rule in 210.8(A) covers 125-volt through 250-volt receptacles on single-phase circuits rated 150 volts or less to ground, and laundry areas are a listed location. A 240-volt dryer receptacle in the laundry area therefore needs GFCI protection.
