What’s on the Journeyman Electrician cheat sheet
- Wiring Methods & Materials (~22%) — EMT, NM cable, and RMC support rules by article, plus the small-conductor breaker caps and Article 300 general requirements.
- Branch Circuits & Conductors (~18%) — ampacity from Table 310.16, conductor sizing, and conduit fill (53/31/40%) and box-fill counting (314.16).
- Overcurrent, GFCI/AFCI & Devices (~16%) — the 240.4(D) small-conductor rule, continuous-load 125% sizing, and where GFCI and AFCI protection is required.
- Services & Grounding (~21%) — minimum 100 A dwelling service, the 83% dwelling allowance, and grounding vs. bonding with GEC/EGC sizing.
- Theory, Feeders & Load Calcs (~23%) — Ohm's law and power, the 1.732 three-phase factor, voltage drop, and dwelling demand factors (3 VA/sq ft).
How to use it in your final week
- Lock in the calculation shortcuts first — Ohm's law (E = I × R), P = E × I, and the 1.732 (√3) three-phase multiplier — since calculations and conductor sizing move your score the most.
- Rehearse the fill numbers until they're reflexive: conduit fill is 53% for one conductor, 31% for two, 40% for three or more; box fill counts each device yoke as two and all grounds together as one.
- Read the grounding-vs-bonding block the night before — GEC caps at 6 AWG copper to a rod and 4 AWG copper to a Ufer, EGC is sized by breaker rating (Table 250.122).
- Pair each review pass with a short timed practice set so open-book code lookup feels fast and routine on exam day.

It condenses the NEC facts examiners lean on most: Ohm's law and power formulas, the 1.732 three-phase factor, ampacity and the small-conductor breaker caps, conduit fill and box-fill percentages, grounding versus bonding, and the demand factors for dwelling load calcs — grouped by the domains that carry the most weight.
No — most journeyman exams are open-book on the NEC itself, but outside notes and prep sheets are not permitted at your seat. Use this sheet to cram beforehand and to tab your own code book fast; confirm the allowed references and NEC edition with your state board.
It is built on the National Electrical Code (NFPA 70) and flags where article numbers shifted between the 2017, 2020, and 2023 editions. Because states adopt the code on a lag, always verify which edition your jurisdiction has adopted before you test.
