DBPR's reference list, effective February 2026, says it in one line under NFPA 70: "2023 edition. Effective August 21, 2027, the 2026 edition will be used for the exam." So for every Florida electrical exam booked through August 20, 2027, the book is the 2023 NEC, and the answer key was written from it.
That matters because the internet has moved on. The 2026 NEC came out, the code-change videos came out with it, and a candidate who studies from a 2026 guide will walk in with a handful of confidently wrong answers. I wrote our bank from the 2023 text page by page and kept every place the two editions disagree. This is the short list.
What changes on August 21, 2027
Not just the NEC. The same reference list moves NFPA 72 from 2019 to 2025, NFPA 780 from 2017 to 2026, the OSHA regulations from the July 2020 edition to 2025, the Florida Contractors Manual from 2021 to 2025, and the NTC Blue Book from 2020 to 2025. If your exam date is after August 20, 2027, every book on the desk changes. If it is before, none of them do.
Where a 2026 study guide gets the 2023 exam wrong
Load calculations live in Article 220. The 2026 edition moved them to Article 120 in Chapter 1. On the 2023 exam, a dwelling load calc is 220.82, the range table is 220.55, the EV charging load is 220.57. Tab Article 220, in the middle of the book.
EV charging (Article 625). The 2023 text has no emergency shutoff requirement and no 125 percent rule for attachment plugs. The 625.43 disconnect is required only above 60 amperes or above 150 volts to ground. 220.57 sizes the EVSE load at 7,200 VA or the nameplate, whichever is larger. Newer guides add rules that are not in the 2023 book.
Pools (Article 680). 680.26(B) equipotential bonding is solid copper only; the 2023 text does not admit copper-clad steel. 680.5(B) covers equipment not over 60 amperes, single or three phase. The 680.14 wiring-method list has no liquidtight flexible metal conduit.
PV and interconnection (690 and 705). 690.9(D) is about transformers; there is no "PV" marking rule for overcurrent devices. 690.7(D) has no rounding allowance. 705.11 has no distance rule for the overcurrent device (that is Article 230 Part VII), and 705.13 and 705.28 rely on an energy management system per 750.30.
Emergency systems (700). 700.12(C) is duration, 700.12(D) is generators, 700.12(H) is unit equipment. 700.10(D)(2) accepts 2 inches of concrete. Article 701 has no surge-protection rule; 760.33 does exist.
Marinas (555). 555.5 is 250 volts (600 under engineering supervision). 555.13 is solid copper, 8 AWG minimum, to the panelboard bus. Marina demand factors are Table 220.120, referenced from 555.6.
Temporary installations (590). The lettering is 590.4(B) feeders, (C) branch circuits, (D) receptacles, (E) disconnects, (F) lamps with no LED exception, (G) splices, (J) support.
Chapter 7 numbering. The 2023 low-voltage articles are 722, 724, 725, 726 and 760. There is no 720, 721, 723, 742 or 772. 722.135(E) is the substitution table.
Every question in our bank that touches one of these carries its 2023 section and, in the source notes, the 2026 reference it will map to when the exam changes. When August 2027 comes, the content is re-verified against the 2026 text before the switch, and the badge on every page says which edition you are reading.
What to do with this
Buy or borrow the 2023 book. Tab Article 220. Ignore any change video dated 2025 or later until your exam is booked after August 20, 2027. And if you are not sure which side of the date you will land on, book the exam first and then choose the book.
