Giải thích
Section 210.8(F) requires GFCI protection for outdoor outlets that supply dwelling equipment rated 150 V or less to ground and 60 A or less, including many HVAC condenser units. AFCI and surge protection do not address the outdoor shock hazard, and 'no protection' does not meet the rule.
