Exam Details

The Delaware Master Electrician examination is administered as part of the licensing process overseen by the Delaware Board of Electrical Examiners. Applicants pursuing licensure by examination must receive approval before scheduling the test with the approved examination provider.

The examination contains 80 questions, and candidates are allowed three hours to complete it. The passing score for Delaware electrical examinations is 75 percent.

The exam outline covers 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.

General Electrical Knowledge includes 19 questions. Preparation should address voltage, current, resistance, power, alternating current, direct current, single-phase systems, three-phase systems, transformers, electrical loads, conductor properties, power factor, and common formulas.

Plan Reading includes four questions. Candidates may need to interpret electrical symbols, panel schedules, equipment locations, conductor sizes, feeder routes, one-line diagrams, circuit information, project notes, dimensions, and installation details.

Equipment for General Use includes five questions. This category may involve switches, receptacles, luminaires, appliances, heating equipment, generators, transformers, capacitors, storage batteries, and other commonly installed electrical devices.

Wiring and Protection includes 15 questions. Candidates should prepare for branch circuits, feeders, services, load calculations, conductor ampacity, overcurrent protection, grounding, bonding, service equipment, panelboards, and disconnecting means.

Wiring Methods and Materials also includes 15 questions. Study should include conductors, raceways, cable assemblies, boxes, fittings, enclosures, supports, securing requirements, wet locations, exposed installations, concealed installations, permitted uses, prohibited uses, and protection from physical damage.

Motors and Controls includes seven questions. Candidates should review full-load current tables, motor conductors, overload protection, short-circuit and ground-fault protection, controllers, disconnecting means, control circuits, and multi-motor installations.

Special Conditions, Special Equipment, and Special Occupancies each include four questions. These areas require candidates to recognize when a dedicated NEC article adds to or modifies a general electrical rule.

Communication Systems includes three questions. Preparation should include cable installation, separation from power conductors, grounding, bonding, and the applicable communication-system requirements.

Open Book Test

The Delaware Master Electrician examination is an open-book test. Candidates may use approved printed reference materials during testing under the examination provider’s current rules.

The American Electrician’s Handbook, 17th Edition; the National Electrical Code, NEC, 2020; and Ugly’s Electrical References are the three references included in this package. Candidates should prepare with the exact editions identified for the examination.

An open-book exam still requires substantial preparation. Eighty questions must be completed within three hours, which limits the amount of time available for researching each answer. Candidates should understand the electrical subject first and then use the appropriate book to confirm the code rule, formula, table, or technical detail.

The National Electrical Code is organized into chapters, articles, parts, sections, tables, and annexes. Candidates should become familiar with its table of contents, index, Article 100 definitions, exceptions, informational notes, cross-references, and commonly used tables.

A productive navigation method begins by identifying the main subject of the question. Branch-circuit questions may lead to Article 210. Feeder questions may involve Article 215. Service questions may require Article 230. Grounding and bonding questions commonly lead to Article 250.

Motor questions may involve Article 430, while transformer questions may require Article 450. Wiring-method questions may lead to articles covering raceways, cable assemblies, conductors, boxes, fittings, or specific environmental conditions.

The American Electrician’s Handbook is useful for electrical theory, calculations, motors, transformers, controls, testing, equipment operation, troubleshooting, and practical field applications. Ugly’s Electrical References can provide quick access to formulas, conversions, conductor data, and motor information.

Candidates should practice selecting the correct book before beginning a search. A code-installation question will usually begin with the NEC. A theory or equipment-operation question may be easier to research in the handbook. A quick formula, conversion, or field value may be found efficiently in Ugly’s Electrical References.

Reference material should always be read in context. Definitions, exceptions, table notes, conditions, and related sections may affect the answer. Candidates should avoid relying on one isolated sentence without reviewing the complete provision.

Before testing, candidates should review the current rules for book preparation. Requirements may address permanent tabs, highlighting, handwritten notes, removable markers, loose paper, photocopies, inserts, calculators, and other permitted or prohibited materials.

Licensing Steps

Begin by reviewing the Delaware Master Electrician license requirements and confirming that this classification matches your experience, qualifications, and intended scope of work.

Create an account through Delaware Professional Regulation Online Services and begin the Master Electrician application. Delaware professional license applications are submitted through the DELPROS system.

Select the appropriate application pathway. Master Electrician applicants may apply by examination or reciprocity, depending on their current licenses, education, experience, and qualifications.

Gather the supporting documentation required for the selected pathway. This may include employment verification, experience records, education information, current license verification, and other materials requested by the Delaware Board of Electrical Examiners.

Submit a complete application and all required documents through DELPROS. The Board reviews the application to determine whether the applicant qualifies for examination authorization or reciprocity consideration.

Applicants pursuing licensure by examination must receive Board approval before scheduling the test. After approval, the examination provider supplies registration and scheduling instructions.

Prepare with the listed references. Review electrical theory, calculations, plans, wiring methods, grounding, bonding, protection systems, motors, controls, equipment, special occupancies, special conditions, and communication systems.

Schedule and complete the Delaware Master Electrician examination. Candidates should confirm identification requirements, testing procedures, permitted references, calculator rules, and appointment details before the test date.

After earning the required passing score, complete any remaining licensing requirements. Master Electrician applicants must provide proof of liability insurance of at least $300,000 before the license can be issued.

The Board office must receive the official examination score and confirm that all application requirements have been completed. Passing the examination alone does not automatically issue the license when documentation, insurance, fees, or other requirements remain outstanding.

State Requirements

Delaware requires individuals performing regulated electrical services to hold the appropriate professional electrician license unless a specific legal exemption applies. Electrical work includes activities covered by the National Electrical Code as adopted in Delaware.

The Delaware Board of Electrical Examiners regulates Master, Limited, Master Special, Limited Special, Journeyperson, Residential, and Apprentice Electrician licenses.

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

Applicants should submit complete, accurate, and consistent records through DELPROS. Missing employment information, incomplete documentation, or conflicting application details may delay review or examination authorization.

The Delaware Board of Electrical Examiners determines whether an applicant meets the requirements for examination and licensure. The testing provider administers the examination but does not decide whether an applicant qualifies for a Delaware license.

Applicants using reciprocity must submit the documentation required for the Board to evaluate the current license held in another jurisdiction and compare the licensing requirements with Delaware standards.

After passing the exam, applicants must complete all remaining licensing requirements before the license can be issued. These may include insurance documentation, fees, or additional materials requested through the application process.

Active Delaware Master Electricians are subject to renewal and continuing education requirements. During a full licensing period, active Master Electricians must complete 10 hours of approved continuing education. Beginning with the second renewal, five hours must relate to the National Electrical Code.

A Delaware professional electrician license is separate from a business license. Individuals planning to operate an electrical contracting company may also need to address business registration, entity formation, taxation, insurance, and local operational requirements.
