Exam Details

Delaware electrical licensing examinations are administered by ProV for the Delaware Division of Professional Regulation. The Delaware Board of Electrical Examiners must approve a candidate before the candidate can sit for the required examination. After approval, candidates receive examination registration information from ProV and schedule the examination through the testing provider.

The Delaware Master Electrician examination is computer-based, open book, and timed. The current Delaware master electrician exam description lists 80 questions and 3 hours of testing time. Delaware requires a minimum score of 75 percent to pass the electrical licensing examination.

The Delaware Master Electrician examination outline includes general electrical knowledge, plan reading, equipment for general use, wiring and protection, wiring methods and materials, motors and controls, special conditions, special equipment, special occupancies, and communication systems. These subject areas require candidates to understand both practical electrical work and NEC-based code requirements.

The master electrician exam is designed around the work of a person licensed by the Board to plan, estimate, lay out, perform, or supervise the installation, erection, or repair of electrical conductors, ducts, raceways, conduits, machinery, apparatus, devices, or fixtures used for lighting, heating, or power in a structure. This broad scope makes structured preparation especially important.

Delaware states that electrical examinations are based on the most up-to-date National Electrical Code adopted in Delaware. This product is based on the 2026 National Electrical Code and includes the NEC 2026 paperback for current-code study, code navigation practice, and advanced electrical preparation.

Open Book Test

The Delaware Master Electrician examination administered by ProV is open book. Candidates may use authorized reference materials during the exam. The exam is still timed, so candidates should know how to move through the code book and other approved references efficiently before test day.

Open-book testing does not remove the need for preparation. Candidates who are unfamiliar with the NEC may spend too much time searching for articles, tables, definitions, and exceptions. A stronger approach is to practice regularly with the code book before the exam, learn the structure of major NEC articles, and build confidence finding information under time pressure.

Reference materials are subject to testing provider rules. Candidates should prepare approved books in a clean and compliant way before the examination. Study guides and calculation practice materials are valuable for preparation, but only authorized references are allowed in the testing room. Students should match their exam-room materials to the current Delaware and ProV instructions for the license examination they are scheduled to take.

The National Electrical Code 2026 paperback included in this combo helps students develop the habits needed for open-book exam performance. Students can practice locating service rules, feeder and branch-circuit requirements, wiring methods, equipment rules, motor requirements, special occupancy provisions, communication system rules, and calculation-related tables. Repeated practice helps reduce wasted time and improves confidence during timed testing.

Licensing Steps

Delaware master electrician candidates begin by applying through DELPROS, the Delaware Professional Regulation Online Services system. Applicants create or log into a DELPROS account and begin the application for the license type they are pursuing. Delaware allows Master and Limited Electrician applicants to apply by examination or by reciprocity, depending on whether they hold a current electrical license of the same type from another state, U.S. territory, or the District of Columbia.

For examination applicants, the Board of Electrical Examiners must approve the candidate before the exam can be taken. The application requires the state application, fee, and supporting documentation. Examination applicants must submit proof of experience. The experience requirement depends on the license type and whether the applicant completed a registered or approved apprenticeship program.

For the Delaware Master Electrician license, applicants who have not completed a registered or approved apprenticeship program must document six years of full-time experience, or four years of full-time experience under a Master Electrician and an official transcript showing two years of technical training. Applicants who completed a registered or approved apprenticeship program and are applying for a Master, Limited, or Special license submit a copy of the Certificate of Completion of Apprenticeship.

Experience after June 30, 2012, obtained in Delaware must have been earned while the applicant was licensed as an Apprentice Electrician or Journeyperson Electrician. Verification of employment forms may be required from each employer, and documentation must show qualifying full-time experience under appropriate supervision.

After the Board approves the application, the candidate receives exam registration information from ProV. The candidate then schedules the examination appointment. Delaware testing options include traditional in-person testing and online testing through Examroom when available through the testing provider’s system.

After passing the examination, Master and Limited Electrician applicants must submit proof of general liability insurance of at least $300,000. The license cannot be issued until the Board office receives proof of insurance and validates that all licensure requirements have been met.

State Requirements

Delaware requires a professional electrician license to perform electrical services or electrical work. The Board defines electrical services or electrical work as activity covered by the National Electrical Code as adopted by the Delaware State Fire Commission. The licensing system includes apprentice, residential, journeyperson, master, limited, master special, and limited special categories.

The Delaware Master Electrician license is the advanced general electrical license category. A master electrician may plan, estimate, lay out, perform, or supervise electrical installation, erection, and repair work involving conductors, raceways, conduits, machinery, apparatus, devices, and fixtures for lighting, heating, or power in a structure.

Master Electrician applicants must meet Delaware’s experience or education pathway, submit the required application and documentation through DELPROS, receive Board approval, pass the required examination, and provide proof of general liability insurance of at least $300,000 before the license is issued. Applicants must also provide state or jurisdiction licensure verification from each jurisdiction where they currently hold or have ever held a license.

Delaware also recognizes specialty categories. Master Electrician Special areas include electric signs, elevators, HVAC, primary distribution systems, pools, and refrigeration. Limited Electrician Special areas include HVAC and pools. Candidates should select the license class that matches the scope of work they intend to perform.

Test Information and Study Materials

A strong Delaware Master Electrician study plan should combine NEC reading, trade-topic review, calculation practice, and timed reference navigation. The exam includes 80 questions across multiple subject areas, so candidates should avoid studying only one topic. A balanced routine helps build readiness across general electrical knowledge, plan reading, wiring methods, wiring protection, equipment, motors, special conditions, special equipment, special occupancies, and communication systems.

General electrical knowledge should include electrical theory, circuit behavior, basic calculations, conductor characteristics, equipment ratings, safety awareness, and practical field concepts. Master-level candidates should be able to connect these fundamentals to NEC rules and real installation conditions.

Wiring and protection is a major study area. Students should review services, feeders, branch circuits, overcurrent protection, grounding and bonding, conductor protection, disconnecting means, panelboards, and related NEC rules. These topics often require candidates to interpret the question carefully and determine which code article or table applies.

Wiring methods and materials require steady code navigation practice. Students should review raceways, cables, boxes, fittings, conductors, insulation types, support requirements, fill requirements, environmental conditions, and installation limitations. Many exam questions in this area test whether the candidate can identify the correct wiring method or recognize when a particular installation condition changes the rule.

Motors and controls are also important for master electrician preparation. Candidates should review motor branch circuits, overcurrent protection, overload protection, disconnects, controllers, conductors, and basic control concepts. Motor questions may require both code lookup and calculation ability.

Electrical calculations should be practiced repeatedly. Students should work on load calculations, conductor ampacity, voltage drop concepts, raceway fill, box fill, motor calculations, overcurrent protection, service and feeder sizing, grounding conductor sizing, and equipment rating questions. A dependable calculation process helps reduce mistakes: read the question carefully, identify the topic, locate the controlling rule or table, set up the calculation, solve it, and check whether the question asks for a minimum, maximum, adjusted value, or final selection.

The 2026 Electrician Calculations Study Guide supports this part of preparation by helping students focus on the math side of electrical exam readiness. Many calculation mistakes happen because the candidate uses the wrong table, skips a condition in the question, rounds too early, or chooses an answer before confirming what the question is asking. Consistent practice helps improve speed and accuracy.

The 2026 Delaware Master Electrician Study Guide supports broader exam-topic review. Master electrician questions often require candidates to connect several concepts at once. A question may involve wiring method, overcurrent protection, conductor sizing, equipment requirements, special occupancy rules, or communication system knowledge. Organized study materials help students move through these topics with a clearer plan.
