Candidates should prepare for subjects involving voltage, current, resistance, power, alternating current, direct current, single-phase systems, three-phase systems, transformers, conductor properties, electrical loads, power factor, and common electrical calculations.

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 area may involve switches, receptacles, luminaires, appliances, transformers, generators, capacitors, storage batteries, heating equipment, and other commonly installed electrical devices.

Wiring and Protection includes 15 questions. Preparation should include branch circuits, feeders, services, conductor ampacity, overcurrent protection, grounding, bonding, disconnecting means, service equipment, panelboards, voltage limitations, and load calculations.

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 installations, concealed installations, permitted uses, prohibited uses, and protection from physical damage.

Motors and Controls includes seven questions. Study should cover 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 subjects require candidates to recognize when a dedicated NEC article supplements or modifies a general installation rule.

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

Open Book Test

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

The approved references include the American Electrician’s Handbook, 17th Edition; the National Electrical Code, NEC, 2020; and Ugly’s Electrical References. Candidates should prepare with these exact editions and become familiar with the organization of all three books before exam day.

An open-book examination still requires substantial preparation. Eighty questions must be completed within three hours, leaving limited time to search through lengthy references. Strong performance requires electrical knowledge, calculation ability, subject recognition, and efficient book navigation.

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

A productive search 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 covering raceways, cables, boxes, fittings, conductor installations, or environmental conditions.

The American Electrician’s Handbook supports electrical theory, calculations, transformers, motors, controls, conductors, equipment, testing, troubleshooting, and practical field applications. Ugly’s Electrical References provides quick access to formulas, conversions, conductor information, motor data, and commonly used electrical tables.

Candidates should practice choosing the correct reference before searching. A code-installation question will generally begin with the NEC, while a theory or practical equipment question may be better addressed through the handbook. A formula or quick technical value may be easier to locate in Ugly’s Electrical References.

Reference material should always be read in context. Definitions, exceptions, table notes, conditions, and related sections may change how a requirement applies. Candidates should avoid selecting an answer based only on a single line without reviewing the surrounding information.

The current testing rules permit specific forms of book preparation, including highlighting, underlining in pen, and permanent tabs. Handwritten notes, removable tabs, Post-it notes, added photocopies, and photocopied reference books are not permitted. Candidates should review the latest testing instructions before preparing their books.

Licensing Steps

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

Create an account through Delaware Professional Regulation Online Services and begin the 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, professional experience, education, and qualifications.

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

Submit a complete application and all required supporting 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. After approval, Prov provides the candidate with examination registration and scheduling information.

Schedule the Delaware Master Electrician examination and review all test-day requirements. Confirm the appointment details, identification requirements, permitted references, calculator rules, check-in procedures, and testing policies.

Use the online course and approved reference books to prepare. Complete electrical theory review, calculation exercises, NEC navigation practice, plan-reading activities, and timed exam simulations.

Take the examination and earn the required passing score. The official result is reported through the testing and licensing process.

After passing, complete any remaining licensing requirements. Master Electrician applicants must submit 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 requirements have been satisfied. Passing the test 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 provide complete, accurate, and consistent records through DELPROS. Missing documentation, incomplete employment information, or conflicting application details may delay review or examination authorization.

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

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 licensing standards with Delaware requirements.

After passing the exam, applicants must complete any remaining licensing requirements before the license can be issued. This may include insurance documentation, fees, or other materials requested through the licensing process.

Active Delaware Master Electricians are subject to renewal and continuing education requirements. Electrician licenses expire on June 30 of even-numbered years and must be renewed through DELPROS.

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, tax accounts, entity formation, insurance, and other operational approvals.
