Exam Details

The Delaware Limited Electrician examination is administered through the state’s approved testing provider as part of the licensing process overseen by the Delaware Board of Electrical Examiners. Applicants must receive Board approval before scheduling the examination.

The examination contains 70 questions, and candidates are allowed three hours to complete the test. A minimum score of 75 percent is required to pass Delaware electrical licensing examinations.

The exam covers General Electrical Knowledge, Equipment for General Use, Wiring and Protection, Wiring Methods and Materials, Special Equipment, and Communication Systems. These areas require candidates to combine practical electrical experience with technical knowledge and code interpretation.

General Electrical Knowledge may involve voltage, current, resistance, power, alternating current, direct current, series circuits, parallel circuits, conductors, transformers, loads, and common electrical calculations. Candidates should understand the principles behind the formulas rather than relying only on memorization.

Equipment for General Use may include switches, receptacles, luminaires, appliances, heating equipment, transformers, generators, capacitors, motors, controllers, and other commonly installed devices. Candidates should know which NEC article applies to each equipment category.

Wiring and Protection is a major exam area. Preparation should include branch circuits, feeders, services, conductor ampacity, overcurrent protection, grounding, bonding, disconnecting means, service equipment, panelboards, and load calculations.

Wiring Methods and Materials is also heavily represented. Candidates should review conductors, raceways, cable assemblies, boxes, fittings, enclosures, support methods, securing requirements, wet locations, concealed installations, exposed installations, and protection from physical damage.

Special Equipment questions may require candidates to apply dedicated NEC articles beyond the general wiring rules. Communication Systems may involve cable installation, separation from power conductors, grounding, bonding, and system-specific requirements.

The examination is computer based and timed. Candidates should develop a pacing strategy that allows time for direct-answer questions, calculations, code research, and final review.

Open Book Test

The Delaware Limited Electrician examination is an open-book test. Candidates may use approved printed reference materials under the current rules established by the examination provider.

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

An open-book format does not eliminate the need for study. The references contain extensive technical material, and candidates cannot expect to search every question from the beginning. Efficient performance requires electrical knowledge, subject recognition, and familiarity with the books.

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

A practical search method begins by identifying the main subject of the question. Branch-circuit requirements may lead to Article 210. Feeder questions may involve Article 215, while 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, boxes, fittings, or conductor installations.

The American Electrician’s Handbook supports questions involving electrical theory, calculations, equipment operation, motors, transformers, controls, testing, troubleshooting, and practical field applications. Candidates should practice deciding which reference offers the most direct path to the answer.

When locating a rule, candidates should read the surrounding material. Definitions, exceptions, table notes, conditions, and related sections may affect how a provision applies. A single sentence may not contain the complete requirement.

Timed reference-navigation practice is recommended. Select a subject, identify the appropriate book, locate the relevant section, and confirm the answer. Repeating this process can improve speed, accuracy, and confidence.

Candidates should review current examination rules before test day. Testing requirements may address permitted tabs, highlighting, handwritten notes, inserts, loose paper, removable markers, calculators, identification, and other materials.

Licensing Steps

Begin by reviewing the Delaware electrician license classifications and confirming that the Limited Electrician license matches the electrical work you plan to perform. Delaware regulates several electrician classifications, each with its own qualifications and scope.

Create an account through Delaware Professional Regulation Online Services. Electrician applications are submitted through the DELPROS licensing system.

Select the appropriate application pathway. Applicants seeking Master or Limited Electrician licensure may apply by examination or reciprocity, depending on their qualifications and current licensing status.

Gather the supporting records required for the application. Documentation may include employment verification, experience records, education information, current license verification, or other materials requested by the Delaware Board of Electrical Examiners.

Submit the completed application and supporting documents through DELPROS. The Board reviews the application to determine whether the applicant qualifies for examination authorization or another available pathway.

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

Schedule the Delaware Limited Electrician examination and review the current candidate information. Confirm the test date, testing method, identification requirements, permitted references, calculator rules, and examination procedures.

Prepare with the American Electrician’s Handbook and the 2020 National Electrical Code. Review electrical theory, calculations, wiring methods, grounding, bonding, protection, equipment, and reference navigation.

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

After passing, complete any remaining requirements shown in DELPROS. Applicants for Master and Limited Electrician licenses must submit proof of liability insurance of at least $300,000 before the license can be issued.

The Board office may require time to receive and process the official examination score. The license is issued after the Board confirms that the applicant has completed all applicable requirements.

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 activities covered by the National Electrical Code as adopted by the Delaware State Fire Commission.

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

The Limited Electrician license has a defined scope. Candidates should understand the work permitted under the classification and should not assume that it provides the same authority as a Master Electrician or another license type.

Applicants must submit complete and consistent information. Missing employment records, incomplete documentation, or conflicting application details may delay Board review or examination approval.

The Board must approve examination candidates before they schedule the test. The examination provider administers the test but does not decide whether an applicant meets Delaware’s licensing qualifications.

Applicants using reciprocity must provide the documentation required for the Board to evaluate their current license from another jurisdiction. The Board determines whether the other jurisdiction’s standards satisfy Delaware requirements.

After passing the examination, applicants must complete all remaining licensing requirements. Passing the test alone does not automatically issue the license when insurance, documentation, fees, or other items remain outstanding.

Active Delaware Limited Electricians are subject to continuing education requirements. During a full renewal period, active Limited Electricians must complete ten 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 to address business formation, registration, taxation, insurance, and other operational requirements.
