Open Book Test

The Delaware Residential Electrician examination is an open-book, timed test. Candidates may use authorized references while following the testing provider’s current requirements for approved titles, editions, highlighting, permanent tabs, notes, inserts, calculators, and other materials.

An open-book format does not eliminate the need for thorough preparation. Candidates have three hours to complete 60 questions. Electrical calculations, unfamiliar Code provisions, and long reference searches can consume valuable testing time, making book familiarity and an organized search method important parts of exam preparation.

The NFPA 70: National Electrical Code, 2020 supports examination questions involving residential services, feeders, branch circuits, conductor ampacity, grounding and bonding, overcurrent protection, wiring methods, equipment, appliances, motors, special installations, and communication systems.

The American Electrician’s Handbook, 17th Edition supports preparation involving electrical theory, formulas, calculations, conductor properties, materials, equipment, motors, controls, testing procedures, and practical electrical knowledge.

Develop a repeatable reference-search process while completing the course. Begin by identifying the main subject and key terms in the question. Decide whether the problem is primarily a National Electrical Code question, an electrical calculation, or a general electrical-knowledge question. Select the appropriate reference, use the index or table of contents, and review the complete applicable section.

When using the National Electrical Code, read article titles, scope statements, definitions, exceptions, table headings, footnotes, and cross-references carefully. The correct answer may depend on conductor material, insulation rating, wiring method, dwelling type, equipment rating, connected load, environmental condition, or another detail provided in the question.

When using the handbook, identify the relevant formula, theory, diagram, table, or equipment discussion. Track units carefully and verify that the final result matches the type of answer requested. A correct formula can still produce an incorrect answer when values are entered improperly or units are not converted correctly.

Authorized references may be prepared using highlighting, underlining in pen, and permanent tabs. Handwritten notes, moveable tabs, repositionable notes, photocopied inserts, and unauthorized study materials are not permitted in the testing room. Candidates should review the current examination instructions before preparing or bringing reference books.

Licensing Steps

The Delaware Board of Electrical Examiners regulates Residential Electrician licenses. Applicants must complete the professional licensing process and receive Board approval before taking the Delaware Residential Electrician examination.

1. Create or access a DELPROS account. Delaware professional licensing applications are submitted through the state’s online licensing system.
2. Apply for the Residential Electrician license. Complete the application and provide the personal, training, employment, experience, examination, and licensing information requested by the Board.
3. Select the applicable qualification pathway. Applicants must document qualifying electrical experience under approved supervision or completion of a residential apprenticeship program approved by the Board.
4. Gather employment documentation. Experience verification may need to be completed by the licensed electrical professional who supervised the qualifying work.
5. Provide apprenticeship records when applicable. Applicants using the apprenticeship pathway must submit the documentation requested by the Board.
6. Arrange for license verification when required. Verification may be required from jurisdictions where the applicant currently holds or previously held an electrical license.
7. Submit additional records as directed. The Board may request supporting forms or third-party documents before completing its review.
8. Receive Board approval to test. The application and supporting records must be approved before the candidate may register for the examination.
9. Register with the testing provider. Follow the examination registration and scheduling instructions provided after approval.
10. Prepare the authorized references. Confirm that the books, tabs, highlighting, calculator, and other materials comply with the current examination rules.
11. Take the Residential Electrician examination. Bring the required identification and follow all testing-center procedures.
12. Complete remaining licensing requirements. The Board must receive the passing examination result and determine that all licensing requirements have been satisfied before issuing the license.

Applicants should begin collecting supporting documentation early. Employment verification, apprenticeship records, and license verification from another jurisdiction may require action by supervisors, employers, training programs, or licensing authorities.

This online exam prep course does not include Application Service or submission of the Delaware licensing application. Candidates remain responsible for documenting their qualifications, paying applicable government and testing fees, obtaining approval, and completing all licensing requirements.

State Requirements

Delaware requires individuals performing regulated electrical services to hold the appropriate professional license. The Residential Electrician classification authorizes qualifying residential electrical work within the scope established by Delaware law.

Applicants must document more than 4,000 hours of full-time electrical experience under the supervision of a licensed Limited Electrician or Master Electrician, or successfully complete a residential apprenticeship program approved by the Delaware Board of Electrical Examiners.

All Residential Electrician applicants must pass the Delaware Residential Electrician examination. Holding a residential electrical license from another jurisdiction or possessing an apprenticeship completion certificate does not eliminate the Delaware examination requirement.

Experience documentation should establish qualifying supervision and describe the electrical work performed. Relevant residential experience may include services, feeders, branch circuits, cables, raceways, receptacles, switches, lighting, appliances, grounding, bonding, overcurrent protection, motors, controls, testing, maintenance, alteration, and repair.

The Delaware Board determines whether an applicant’s experience, apprenticeship records, examination results, license verifications, and supporting documentation satisfy the licensing requirements. Completing an online exam prep course does not replace any application, experience, apprenticeship, examination, or professional licensing requirement.

A Delaware Residential Electrician license is issued to an individual. An electrician planning to operate a contracting business may also need entity registration, a Delaware business license, tax accounts, insurance, permits, inspections, and other state or local credentials.

Professional licensing, business licensing, electrical permits, inspections, and local registrations may involve separate agencies and processes. Candidates should understand the difference between qualifying for an individual professional license and establishing a business that is legally authorized to operate.
