Correct answer to question 7020
- C: A noncombustible nonmetallic faceplate with nonmetallic screws, or GFCI protection
Explanation
An exception to 404.9(B) covers replacements where no grounding means exists. The switch then needs a nonmetallic, noncombustible faceplate with nonmetallic screws, or the circuit must be GFCI protected.
