Code Change Summary: New code section. GFCI protection is now required for outdoor “outlets” at dwellings.
An “Outlet”, according to the NEC Article 100 definition, is a point on the wiring system at which current is taken to supply utilization equipment.
Many people make the mistake of thinking that only receptacles can be “outlets”. A receptacle is one kind of outlet, but so is a hard-wired connection such as a smoke detector, or a surface mounted luminaire, or even the point on an outdoor air conditioner system where the circuit connects to the disconnecting means supplying the AC unit.
In the 2020 NEC, all outdoor “outlets” for dwellings, other than lighting, electric snow-melting, deicing, or pipeline heating, that are supplied by single-phase branch circuits rated 150 volts to ground or less, 50 amperes or less, shall have ground-fault circuit-interrupter protection for personnel. This is a big change!
Example: A 240V, single phase, outdoor, dwelling unit air conditioner has two ungrounded conductors that are each 120V to ground and 240V phase to phase. If this air conditioner is rated 50 amps or less, then GFCI protection is now required for the “outlet”. How about an outdoor well pump?
This code change came as a result of a child’s death. On August 3, 2007, a 12-year-old child jumped over a chain link fence and landed on the adjacent AC condenser unit. The condenser had an electrical ground fault which caused the unit's metal housing to become electrified. The child was fatally electrocuted when he made contact simultaneously with both the condenser and the metal fence.
