Correct answer to question 4034
- C: GFCI protection, with a listed Class C SPGFCI permitted
Explanation
In the 2026 edition the HVAC exception to 210.8(F) expires September 1, 2026, so the outlet needs GFCI protection, and a listed Class C special purpose GFCI is permitted for listed HVAC equipment. Note: under the Texas adoption, TDLR extended the HVAC exception without an expiration date, so this outlet would not need GFCI in Texas.
