Article 590 is short and almost every item is a number (90 days, 150 V, 10 ft, 3 months, 600 V, 10,000 A) or a which-receptacles-get-GFCI rule. Written from the 2023 text (the Florida edition; 2023 section numbers throughout — 590.1 scope, 590.2 all wiring installations, 590.3 time constraints, 590.4 general, 590.5 listing of decorative lighting, 590.6 GFCI, 590.7 guarding, 590.8 overcurrent devices).
