Connecticut E-2 Unlimited Electrical Journeyperson • PSI • 80 Questions • 210 Minutes
Prepare for the Connecticut Journeyman Electrician Exam with a study plan covering electrical theory, the National Electrical Code, raceways, conductors, electrical services, feeders, branch circuits, grounding, bonding, motors, fire alarms, photovoltaic systems, overcurrent protection, and jobsite safety.
The official Connecticut license is the E-2 Unlimited Electrical Journeyperson credential. The license is regulated by the Connecticut Department of Consumer Protection, commonly called DCP, and the Electrical Work Examining Board.
The E-2 examination is administered by PSI Services LLC. The official bulletin lists 80 questions and 210 minutes, or three and a half hours, to complete the test.
To pass, candidates must answer at least 56 questions correctly. That equals the required passing score of 70%.
Connecticut's E-2 examination is open book. Candidates are responsible for bringing their own approved reference materials.
Important codebook distinction: The current PSI bulletin lists the 2020 or 2023 National Electrical Code, or the corresponding NEC Handbook, as approved references. The 2026 NEC is not currently listed as an approved exam-room book.
Contractor Exam Preps offers Connecticut Journeyman Electrician study packages based on the 2026 NEC. These products support electrical learning, code navigation, calculations, and exam-style practice, but the included 2026 NEC should not be treated as an approved E-2 testing reference unless PSI updates its rules.
The 2026 Connecticut Journeyman Electrician Ultimate Combo includes a Connecticut study guide, electrical calculations workbook, 2026 NEC with tabs, flash cards, and online study resources.
The store also offers a 2026 Connecticut Journeyman Electrician Super Combo and a Connecticut Journeyman Study Guide and NEC Combo.
For licensing, the standard E-2 pathway involves completing a registered apprenticeship or at least four years of approved equivalent training and experience.
Connecticut DCP's equivalent-training application specifies 8,000 on-the-job hours and 720 classroom hours. Its broader license-type chart lists 576 related-instruction hours for E-2 apprenticeships. Candidates should verify the requirement applicable to their exact training route with DCP.
One more important distinction: E-2 is a journeyperson license, not an electrical contractor license. The separate E-1 Unlimited Electrical Contractor credential involves additional qualification and contractor examinations.
This guide covers E-2 exam topics, approved books, code-reference rules, licensing qualifications, study products, a six-week plan, and the difference between journeyperson and contractor authority.
Important Connecticut E-2 electrician update: The official Unlimited Electrical Journeyperson examination contains 80 questions, allows 210 minutes, and requires 56 correct answers to pass. The exam is open book with candidate-supplied approved references. The current PSI bulletin permits the 2020 or 2023 NEC or NEC Handbook, not the 2026 NEC included in many newer study packages. Permanent tabs and highlighting prepared before the exam are allowed under PSI rules. DCP's equivalent-training application requires 8,000 work hours and 720 classroom hours, while the general apprenticeship license-type chart shows 576 related-instruction hours. Confirm your specific eligibility pathway directly with DCP.
A Connecticut E-2 Journeyperson Electrician is an electrical professional licensed to perform unlimited electrical work while employed by a properly licensed electrical contractor.
The official state title is E-2 Unlimited Electrical Journeyperson.
The term Journeyman Electrician is still widely used by electricians, training schools, employers, and people searching for electrical licensing information.
Connecticut's E-2 classification covers the electrical work defined by state law, subject to the conditions of the license.
Licensed journeyperson electricians may install, maintain, troubleshoot, repair, and replace electrical systems within their authorized scope.
That work can involve service equipment, branch circuits, feeders, wiring methods, circuit breakers, panels, receptacles, lighting, motors, grounding, and bonding.
Electricians must also understand important safety practices, equipment ratings, and the requirements of the National Electrical Code.
For example, installing a new panelboard is not simply a matter of connecting wires to circuit breakers.
The electrician must evaluate conductor sizes, available space, equipment ratings, grounding, bonding, and other installation conditions.
The E-2 examination measures whether candidates understand these requirements well enough to apply them in different situations.
Connecticut generally requires completion of a registered apprenticeship or acceptable equivalent experience and training.
The state's equivalent-training application identifies 8,000 hours of practical electrical work and 720 classroom hours.
The general DCP trade-license chart lists 8,000 practical hours and 576 related-instruction hours for E-2. Because the published state pages differ, applicants should follow the requirement confirmed for their individual application by DCP and the Connecticut Department of Labor apprenticeship program.
Applicants using equivalent training must provide acceptable proof of education, detailed work history, and employer documentation.
Electrical fieldwork and classroom instruction are both important. The worksite teaches how systems are installed, while classroom instruction helps explain the rules and calculations.
Passing the E-2 examination is an important part of the licensing process, but it does not automatically grant the license.
The applicant must satisfy the state's qualifications and complete the required DCP process.
Another important distinction is that E-2 license holders must perform covered electrical work while employed by a properly licensed contractor.
The E-2 credential is not the same as an E-1 Unlimited Electrical Contractor license.

Use the 2020 or 2023 NEC for questions that require the currently approved code language.
The 2026 NEC can be useful for studying newer electrical concepts, but do not assume the wording and numbering are identical across editions.
The Connecticut Journeyman Electrician and Calculations Combo offers general technical review and electrical math practice based on the 2026 code.
For the actual E-2 exam, make sure your reference practice also includes the specific approved NEC edition and any additional references you plan to bring.
Connecticut's E-2 examination covers electrical services, conductors, raceways, grounding, motors, and photovoltaics. Understanding how these systems connect can help make code questions easier to solve.
Educational diagram only. Actual installation must follow the applicable electrical code.
Follow these eight steps to prepare for the E-2 examination and Connecticut licensing process.
Review the Unlimited Electrical Journeyperson scope of work and confirm you need the E-2 exam.
Gather proof of your registered apprenticeship or qualifying equivalent work experience.
Check the exact education requirement for your pathway, including DCP's 720-hour equivalent-training standard.
Complete the correct licensing application and receive examination eligibility.
Obtain a 2020 or 2023 NEC and any other approved books you plan to use.

Connecticut's E-2 Unlimited Electrical Journeyperson license authorizes the holder to perform electrical work defined by state law while employed by a properly licensed contractor.
Electrical work may involve residential, commercial, and industrial installations.
Journeyperson electricians commonly install, maintain, troubleshoot, and repair electrical equipment, branch circuits, feeders, panels, wiring methods, lighting, and related systems.
The work may also include motors, controls, grounding, bonding, and other equipment within the licensed scope.
An electrician must understand the safe installation of conductors, the correct selection of overcurrent protection, and the requirements for approved wiring methods.
For example, choosing an undersized conductor can lead to overheating. Incorrect grounding or bonding can create serious safety problems.
That is why these subjects are included in the E-2 examination.
Connecticut also tests photovoltaic systems, fire detection, illuminated signs, and other specialized electrical topics.
Being licensed as an unlimited electrical journeyperson requires knowledge beyond a single type of installation.
However, the E-2 license does not provide the independent authority of an unlimited electrical contractor.
The Connecticut DCP scope description states that an E-2 license holder performs electrical work only while employed by a properly licensed contractor.
Electricians who want to operate their own electrical contracting business should review the E-1 Unlimited Electrical Contractor classification.
Connecticut generally requires two years as an unlimited licensed journeyperson or at least six years of approved equivalent experience and training to qualify for the E-1 examination.
The contractor-level process also includes a Business and Law examination.
These requirements help distinguish an experienced electrician performing electrical work from a business owner who takes responsibility for electrical contracting operations.
E-2: Unlimited Electrical Journeyperson.
Employment condition: Work while employed by a properly licensed contractor.
E-1: Unlimited Electrical Contractor.
Future advancement: Additional experience and contractor examinations may be required.
| Classification | License Type | Purpose or Exam Requirement |
|---|---|---|
| E-2 | Unlimited Electrical Journeyperson | Unlimited electrical work while employed by a properly licensed contractor; E-2 trade examination. |
| E-1 | Unlimited Electrical Contractor | Contractor-level authority with additional qualification, trade exam, and Business and Law exam. |
| C-6 | Limited Electrical Journeyperson | Limited electrical work within the C-6 classification. |
| L-2 | Limited Electrical Journeyperson | Electrical line work within the applicable scope. |
| L-6 | Limited Electrical Journeyperson | Work within the state's corresponding limited classification. |
| PV-2 | Limited Solar Journeyperson | Solar-related electrical work within the approved scope. |
| T-2 | Limited Electrical Journeyperson | Telecommunications-related electrical work within the classification. |
| E-2 PSI Exam | Journeyperson Trade | 80 questions, 210 minutes, 56 correct to pass. |
| E-1 PSI Exam | Contractor Trade | 100 questions, 240 minutes, 70% passing. |
| Business and Law | Contractor Examination Portion | 50 questions, 120 minutes, 70% passing. Not required for E-2 journeyperson licensing. |
E-2: Unlimited electrical journeyperson credential.
E-1: Unlimited electrical contractor credential.
Business and Law: Required for contractor applicants, not E-2 applicants.
Exam prep warning: Choose E-2 materials if that is the license you are applying for.
8,000 Qualifying Hours
E-2 Electrical Licensing
Connecticut DCP
Experience: 8,000 qualifying electrical work hours.
Equivalent-training classroom standard: 720 hours according to DCP's specific application instructions.
General apprenticeship chart: Lists 576 hours, so applicants should confirm the requirement applicable to their program and pathway.
License issuance: Passing PSI does not automatically satisfy all state requirements.
Use this schedule to cover Connecticut's sixteen official subjects, approved NEC references, electrical calculations, and open-book time management.
The Connecticut E-2 Unlimited Electrical Journeyperson exam can be challenging because it covers many electrical systems, rather than just the type of work an electrician performs most often.
Candidates must answer 80 questions in three and a half hours.
At least 56 correct answers are needed to pass.
The examination is open book, which means approved references are available. However, you still need to understand how to find and apply the correct rules.
The largest subject is Raceways and Boxes, with eight questions.
General Electrical Knowledge, Services and Feeders, and Conductors and Cables each contain seven questions.
These four categories total 29 questions.
Grounding and Bonding, Overcurrent Protection, and Photovoltaics add another six questions each.
This makes code navigation, wiring methods, and electrical calculations important skills.
Solar electrical systems deserve particular attention because Photovoltaics accounts for 7.5% of the exam.
Fire Detection and Alarm Systems also appears in the official outline, even though many electricians do not regularly work with fire alarms.
Practicing unfamiliar subjects can help you avoid losing easy points.
The approved reference list includes more than the NEC. Candidates can use specified editions of OSHA regulations, Ugly's Electrical References, NFPA 72, photovoltaic texts, and the National Electrical Safety Code.
Knowing which reference contains the answer can make the difference between a quick lookup and several minutes of searching.
Another challenge is the difference between newer study materials and the exam's current reference rules.
Many 2026 electrician packages teach from the 2026 NEC, while Connecticut currently lists the 2020 or 2023 NEC for E-2 testing.
Code changes can affect wording, article structure, or specific requirements. Always prepare with the edition that will be allowed on your examination date.
Practice timed questions until you can recognize the type of problem and locate the correct NEC article quickly.
With careful preparation, the exam becomes more manageable.
An open-book test is still a test. The trick is to know where to look before the clock reminds you how quickly three and a half hours can disappear.
PSI arrival: At least 30 minutes before the examination.
Identification: Valid government-issued identification with a matching registration name.
Calculator: Silent, nonprinting, nonprogrammable calculator.
References: Candidate-supplied and approved by PSI.
Passing: 56 correct answers out of 80.
Contractor Exam Preps offers Connecticut-specific Journeyman Electrician study guides, calculations books, NEC study sets, flash cards, and online practice.
The following packages are based on the 2026 NEC for educational preparation. The included 2026 NEC is not currently listed as an approved Connecticut E-2 exam-room reference.
