What's on the Connecticut E-2 Journeyperson Exam?
The Connecticut E-2 exam has 80 scored questions in 3.5 hours, and you need 70% (56 correct) to pass. It is open book, and PSI allows the 2020 or the 2023 NEC. The counts below are from PSI's Electrical Trades candidate bulletin, updated February 2026.
The outline
| Content area | Questions |
|---|---|
| Raceways and Boxes | 8 |
| General Electrical Knowledge | 7 |
| Service, Feeders, and Branch Circuits | 7 |
| Conductors and Cables | 7 |
| Grounding and Bonding | 6 |
| Overcurrent Protection | 6 |
| Photovoltaics | 6 |
| Special Occupancies and Equipment | 5 |
| Motors | 5 |
| Fire Detection and Alarm Systems | 5 |
| Safety Information | 5 |
| Electrical Power | 4 |
| Lighting | 3 |
| Low Voltage | 2 |
| Illuminated Signs | 2 |
| High Voltage | 2 |
| Total | 80 |
Two things stand out. Photovoltaics is 6 questions, as many as grounding or overcurrent protection, and fire detection and alarm systems is 5. Both are worth more here than on most journeyman exams. The E-1 contractor exam uses the same 16 areas with 100 questions.
Where each area lives in the NEC
PSI does not map its areas to NEC articles. This is where you will find the rules.
- Raceways and Boxes: Articles 300, 312, 314 and the raceway articles (342 to 362), with Chapter 9 conduit fill.
- Service, Feeders, and Branch Circuits: Articles 210, 215, 220, 225 and 230.
- Conductors and Cables: Article 310 ampacity tables and the cable articles (320 to 340).
- Grounding and Bonding: Article 250.
- Overcurrent Protection: Article 240.
- Photovoltaics: Articles 690 and 705, plus 706 for energy storage.
- Special Occupancies and Equipment: Chapters 5 and 6.
- Motors: Article 430 (and 440 for air-conditioning equipment).
- Fire Detection and Alarm Systems: Article 760, plus NFPA 72 (2013 edition), which is on the reference list.
- Electrical Power: Articles 445, 450 and 480, and emergency and standby systems (700 to 702).
- High Voltage: Article 490 and the over-1000-volt parts of Articles 110, 225, 230, 240, 250 and 300.
- Lighting, Low Voltage and Illuminated Signs: Articles 410, 725 and 800, and 600.
- Safety Information: OSHA's construction standards, 29 CFR 1926.
- General Electrical Knowledge: Articles 90, 100 and 110, Chapter 9, and circuit theory.
What you can bring
The exam is open book, and you bring your own references: the 2020 or 2023 NEC (or either Handbook), 29 CFR 1926, Ugly's Electrical References, NFPA 72 (2013), Dunlop's Photovoltaic Systems, the 2012 National Electrical Safety Code and Convert Your Home to Solar Energy. PSI also warns that some questions test trade knowledge and general industry practice beyond the books.
How to study
- Pick one edition and know it. PSI allows both, and Connecticut's code is still the 2020 NEC. If you bring the 2023 book, learn where it moved the rules, such as the renumbered load-calculation tables in Article 220.
- Don't skip PV. Six questions on Articles 690 and 705 are as many as overcurrent protection. Practice PV source-circuit current, conductor sizing and the interconnection rules.
- Tab permanently. Highlighting, underlining and margin notes are allowed, and permanent tabs are allowed; sticky notes are not.
- Use the fire alarm questions. Article 760 power-limited and non-power-limited circuit rules are quick lookups if you know where they are.
Practice for the exam
Our Connecticut E-2 practice test draws from all 16 areas in the same proportions, and every explanation cites the 2020 NEC section. For test-day logistics, see the Connecticut E-2 exam day.
