How the real exam is built
The real exam: 100 questions across 12 areas in 4 h 15 min. Our timed exams use the same areas and weights.
You need 70% (70 of 100). This is the Electrical Contractor trade exam, the first of the three exams every New Jersey license candidate takes; Alarm Systems and Business and Law are separate exams that we do not cover yet. These are the question counts PSI publishes, and our full-length practice exam draws from each area in the same proportions.

No list of qualifying states is published, so ask the Board at (973) 504-6410.

Frequently asked questions
How is the New Jersey Electrical Contractor exam structured?+
The license takes three PSI exams, all open book with 70% to pass: the Electrical Contractor trade exam (100 questions, 4 hours 15 minutes), Alarm Systems (50 questions, 2 hours 45 minutes) and Business and Law (50 questions, 2 hours 10 minutes). On your first attempt you take all three on the same day. The trade exam weighs grounding and bonding most heavily (16 questions), then motors and controls (12), and 10 each for general electrical knowledge (electrical theory and calculations as well as the NEC’s general rules), raceways and enclosures, and services, feeders and branch circuits.
Does this practice exam cover the Alarm Systems and Business and Law exams?+
Not yet. This product covers the Electrical Contractor trade exam, the 100-question NEC exam. The Alarm Systems exam (NEC, NFPA 72-2022 and the NTC low-voltage and video security handbooks) and the Business and Law exam (NASCLA Contractor’s Guide, New Jersey 2nd edition) are separate, and you need to pass them too. We will add them as modules; until then, study them from their reference books.
Which code edition is the exam on?+
The 2023 NEC, per PSI’s bulletin updated March 5, 2026. New Jersey’s Uniform Construction Code also adopted the 2023 NEC on August 17, 2026 (permits filed under the 2020 NEC are accepted until February 17, 2027), so the exam and the code you work under now match. Code questions follow the listed edition only.
Can I bring my own code book?+
Not for the NEC. PSI provides an unmarked 2023 NEC at the test center, and you may not use your own copy or write in, highlight or tab the one provided. Practice finding sections in a clean book. For the Alarm Systems and Business and Law exams you bring the other references yourself; they may be highlighted and permanently tabbed, but not written in.
What do I need before I can sit the exam?+
You must be over 21 with a high school diploma or equivalent, and have five years in electrical construction right before you apply: a completed four-year U.S. Department of Labor accredited apprenticeship, followed by at least one year (2,000 hours) as a journeyman electrician. Apply to the Board ($100 application fee); once approved, you pay PSI and schedule all three exams.
What if I fail one of the exams?+
You retake only the exam you failed, after a six-month wait. You must pass all three within three attempts; failing a section a third time forfeits your passing scores and you start over on all three. Everything must be passed within five years of your approval date.
What is on the Safety area?+
Three questions. PSI says the exam may include questions on trade knowledge and general industry practice beyond the NEC, so our Safety questions come from OSHA’s construction standard (29 CFR 1926) and NFPA 70E, along with NEC arc-flash marking rules.
Does New Jersey have a journeyman exam?+
PSI’s New Jersey bulletin covers only the three electrical contractor exams. The Board also licenses Class A journeyman electricians, Class B wiremen and Class A electrical apprentices; ask the Board at (973) 504-6410 what those licenses require.
