• Special Occupancies: 4 questions
• Communication Systems: 3 questions

General electrical knowledge is the largest individual category. Candidates should be prepared to apply electrical theory, formulas, calculations, conductor relationships, load concepts, equipment characteristics, and practical trade knowledge. The American Electrician's Handbook and Ugly's Electrical References can support this preparation by providing technical explanations, formulas, tables, and field-oriented electrical data.

Wiring and protection and wiring methods and materials account for 30 questions. These areas require strong familiarity with services, feeders, branch circuits, grounding and bonding, overcurrent protection, conductors, cables, raceways, boxes, fittings, conductor ampacity, adjustment factors, correction factors, box fill, raceway fill, securing and supporting, and protection from physical damage.

Motors and controls represent seven questions. Preparation should include motor full-load current tables, conductor sizing, branch-circuit protection, overload protection, disconnecting means, controllers, feeder calculations, transformer rules, and the application of general NEC requirements to motor circuits.

Plan-reading questions may require candidates to interpret electrical symbols, equipment schedules, panel information, circuit designations, conductor routes, installation details, and project conditions. Master electrician preparation should include the ability to connect plan information with the code requirements that apply to the installation.

With 80 questions and three hours available, candidates have an average of approximately two minutes and fifteen seconds per question. Some questions may be answered quickly, while detailed calculations and reference searches may require more time. Timed practice with all three approved references can help candidates build an efficient testing routine.

Open Book Test

The Delaware Master Electrician examination is an open-book, timed test. Candidates may use the approved references identified for the exam when the books comply with ProV’s preparation and inspection rules.

The approved exam-room references are the American Electrician's Handbook, 17th Edition; National Electrical Code, NEC, 2020; and Ugly's Electrical References, 2020. Candidates are responsible for bringing their own approved books to the testing appointment.

References may be prepared before test day using highlighting, underlining in pen, and permanent tabs. Permanent tabs should be securely attached and should not be easily removable. Organized tabs can help candidates move efficiently to important NEC articles, handbook chapters, formulas, motor tables, conductor information, and calculation sections.

Handwritten notes are not allowed in any portion of an approved reference. Moveable tabs, temporary tabs, and Post-it notes are not permitted. Photocopied documents cannot be added to a reference book, and photocopied versions of approved books are not accepted.

Test-preparation study guides and practice examinations are not approved exam-room references. Candidates may not share books or add highlighting, underlining, notes, or markings during the examination.

All references are inspected by the ProV test administrator before the candidate enters the testing room. A book that does not meet the published requirements may be rejected. Prepare each reference carefully before the appointment and remove handwritten notes, loose pages, temporary markers, and unauthorized inserts.

Open book does not mean that answers can be found without preparation. Candidates need to know how each reference is organized, which book is most likely to contain the answer, and where important tables and rules are located. Efficient reference selection can prevent unnecessary searching and protect valuable testing time.

State Requirements

A Delaware Master Electrician is licensed to plan, estimate, lay out, perform, or supervise the installation, erection, and repair of electrical conductors, ducts, raceways, conduits, machinery, apparatus, devices, and fixtures used for lighting, heating, or power in a structure.

Applicants applying by examination must meet the experience requirements established by the Delaware Board of Electrical Examiners. An applicant who completed a registered or approved apprenticeship program may submit the Certificate of Completion of Apprenticeship as proof of experience.

An applicant who has not completed an approved apprenticeship program must document six years of full-time electrical experience under appropriate supervision. Another pathway allows four years of full-time experience under a Master Electrician together with an official transcript showing two years of technical training.

Employment verification should identify the employer, supervising electrician, dates of employment, full-time experience, and the electrical work performed. When an applicant cannot obtain the required Verification of Employment form, the Board may consider W-2 records and a written explanation. Acceptance of alternate proof is determined by the Board.

Electrical experience obtained in Delaware after June 30, 2012 must have been earned while the applicant held the appropriate Apprentice Electrician or Journeyperson Electrician license for the experience to receive credit.

All Master Electrician applicants must submit proof of at least $300,000 in general liability insurance. The applicant’s name must appear on the insurance document, even when coverage is provided through an employer. Candidates may take the examination before submitting the insurance record, but the license cannot be issued until acceptable proof is received.

Applicants holding a current Master Electrician license issued by another state, territory, or the District of Columbia may apply through reciprocity. Additional experience documentation may be required depending on whether the other jurisdiction’s licensing standards are considered substantially similar to Delaware’s standards.

Delaware Master Electricians are also subject to continuing education requirements for license renewal. Active Master Electricians completing a full renewal period must complete the required approved continuing education, including National Electrical Code-related education when applicable.
