Connecticut E-2 journeyperson electrician exam: format, NEC edition and fee
Connecticut's Department of Consumer Protection (DCP), through Occupational Licensing, licenses E-2 unlimited electrical journeypersons, and PSI runs the exam. These facts come from PSI's Electrical Trades bulletin (updated 2/4/2026) and PSI's test listing, read on 9 November 2026. Connecticut sets its own rules and can change them, so confirm with DCP and the bulletin before you book.

Which NEC edition to bring
The E-2 reference list allows the National Electrical Code or the NEC Handbook, in the 2020 or the 2023 edition. The bulletin also says code questions are based only on the edition of the code book that is listed, and this list names both. NFPA's adoption table shows Connecticut on the 2020 NEC with state amendments, with a move to 2023 underway and no effective date set. Ask PSI or DCP which edition your questions are written to before you buy a book. Most skills carry over between editions, but section numbers can move, so practice your lookups in the edition you will bring. The open-book rules guide shows how other states' book rules compare.

What it covers
The E-2 outline lists sixteen areas by item count: General Electrical Knowledge; Service, Feeders and Branch Circuits; Grounding and Bonding; Conductors and Cables; Raceways and Boxes; Special Occupancies and Equipment; Electrical Power; Motors; Low Voltage; Lighting; Illuminated Signs; Fire Detection and Alarm Systems; Safety Information; Overcurrent Protection; High Voltage; and Photovoltaics. Raceways and Boxes is the largest, at 8 items. The bulletin adds that 1 to 10 unscored experimental items may appear, and that questions may draw on trade knowledge and general industry practice.
Besides the NEC, the E-2 reference list names OSHA's construction standards (29 CFR 1926), Ugly's Electrical References (2020 or 2023), NFPA 72 (2013 edition), the National Electrical Safety Code (2012 edition) and two photovoltaic titles. Each NEC area falls into one of the twelve in our journeyman exam outline.
How our practice exam fits
Our practice exam is written to the 2023 NEC, one of the two editions the bulletin lists. It is 100 questions in 240 minutes, longer than Connecticut's 80 in 210, and like Connecticut's journeyperson exam it has no law and rules section. Connecticut gives photovoltaics, fire alarm and high voltage their own items, while our outline folds solar PV into special occupancies and fire alarm into low-voltage systems and does not cover the NESC, so give those extra time. It is not Connecticut's exam. If you do not pass, the bulletin gives you 30 minutes at the end of the exam to review the items you missed, at no charge. See the journeyman exam guide for how other states compare.
