Final answer:
A ground fault circuit interrupter (GFCI) is essential for outdoor receptacles to prevent electrical hazards by quickly detecting and stopping current leakage.
Explanation:
A ground fault circuit interrupter (GFCI) is required for outdoor receptacles according to NEC article 210.8(A)(3). GFCIs prevent shock by detecting loss of current to unintentional paths, enhancing electrical safety. By quickly interrupting the circuit upon detecting a ground fault, GFCIs play a crucial role in preventing electrical hazards.
