Exam Details

The Delaware Master Electrician examination is part of the professional licensing process administered through the Delaware Board of Electrical Examiners. Candidates applying by examination must complete the appropriate licensing application and receive approval before scheduling the test.

The examination contains 80 questions, and candidates are allowed three hours to complete it. The timed format requires candidates to balance direct-answer questions, calculations, code research, plan interpretation, and final review.

The 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.

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

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

Equipment for General Use includes five questions. This subject 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. Preparation should address branch circuits, feeders, services, load calculations, conductor ampacity, overcurrent protection, grounding, bonding, disconnecting means, panelboards, and service equipment.

Wiring Methods and Materials also includes 15 questions. Candidates should review conductors, raceways, cable assemblies, boxes, fittings, enclosures, support methods, securing requirements, wet locations, exposed work, concealed work, permitted uses, prohibited uses, and protection from physical damage.

Motors and Controls includes seven questions. Study should include motor conductors, full-load current tables, 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 dedicated National Electrical Code articles supplement or modify general installation requirements.

Communication Systems includes three questions. Candidates should review cable installation, separation from power conductors, grounding, bonding, system requirements, and the organization of the applicable NEC articles.

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 three books included in this package support preparation for the open-book examination. Highlighting and tabs can make selected subjects easier to recognize and help candidates move between major sections more efficiently.

An open-book examination still requires substantial preparation. The reference materials contain extensive technical information, and candidates cannot depend on researching every question from the beginning. Strong preparation combines electrical knowledge, calculation ability, code familiarity, and efficient reference navigation.

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

A productive navigation strategy 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 direct candidates to articles addressing raceways, cable assemblies, boxes, fittings, conductor installations, or environmental conditions.

The American Electrician’s Handbook supports theory, calculations, motors, transformers, controls, equipment, testing, troubleshooting, and practical electrical applications. Ugly’s Electrical References supports quick review of formulas, calculations, conductor information, motor data, and common field references.

Highlighted passages should always be read in context. Definitions, exceptions, table notes, conditions, and nearby provisions may change how a rule applies. Highlighting is a navigation aid and should not replace reading the complete requirement.

Tabs are most effective when candidates practice using them before exam day. Timed navigation exercises can help candidates learn where major subjects are located and improve their ability to move between the three books.

Candidates should review the current testing rules before bringing references into the exam. Requirements may address highlighting, tabs, handwritten notes, loose paper, inserts, removable markers, photocopied materials, calculators, and other test-day items.

Licensing Steps

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

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

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

Gather the supporting documents required for the selected pathway. These 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 supporting documentation 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. After approval, the testing provider supplies registration and scheduling instructions.

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

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

After passing the examination, complete any remaining documentation, insurance, payment, or administrative requirements associated with license issuance. Passing the examination alone does not issue the professional license when 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 services include work 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 information through DELPROS. Missing records or incomplete documentation may delay Board review and examination authorization.

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

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

After passing the examination, applicants must complete any remaining requirements before the license can be issued. Examination success is only one part of the licensing 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 of those 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 business registration, entity formation, tax accounts, insurance, and other operational approvals.
