Study the 2017 numbering
Most current study material is written for the 2020 or 2023 NEC, which renumbered rules you will look up on this exam:
| Topic | 2023 NEC (not on the G exams) | 2017 NEC (your exam) |
|---|---|---|
| Conductor ampacity table | Table 310.16 | Table 310.15(B)(16) |
| Conductor types and insulation | Table 310.4(1) | Table 310.104(A) |
| Dwelling GFCI receptacles | All 125–250 V receptacles in the listed locations | 125 V, 15 and 20 A receptacles in the listed locations |
| Dwelling general lighting load (3 VA per ft² in both) | 220.41 | Table 220.12 |
Practice with a 2017 code book, and learn where each table lives in it.
How to study
- Start with the biggest areas. Wiring methods, branch circuits and services are about half the exam.
- Learn the 2017 tables by location. Ampacity, conductor properties and box fill come up again and again.
- Practice the small areas too. Feeders, control devices and motors are only a few questions each, but quick points if you know where to look.
