At an agricultural (farm) site, which one of the following locations does not require ground-fault circuit-interrupter protection for all 125V, single-phase, 15A and 20A general-purpose receptacles?

1. an accessible receptacle supplying a dedicated load where a GFCI protected receptacle is located within 3 ft of the non-GFCI protected receptacle
2. areas having an equipotential plane
3. outdoors
4. damp or wet locations
5. dirt confinement areas for livestock

Answer: A

New text at the end of 547.5(G) reads like an exception to the GFCI-protection requirements in agricultural buildings noted in (1) through (4). Dedicated loads include equipment like brooders and incubators, as well as feed mixers, conveyors, and grinders.
