Delaware Master Electrician

One computer exam from Prov: 80 questions in 3 hours, open book, and you need 75% (60 correct). General Electrical Knowledge is the largest area at 19 questions, then Wiring and Protection and Wiring Methods and Materials at 15 each and Motors and Controls at 7. The references are the NEC, the American Electrician’s Handbook and Ugly’s Electrical References. That is 2.25 minutes a question, so tab your code book well.

Knowledge of residential, commercial and industrial work and one of: six years of full-time experience under a licensed master electrician; 8,000 hours under a master plus 576 hours of related instruction, shown by a registered apprenticeship completion certificate from any state; or four years under a master plus two years of technical training (24 Del. C. § 1408(a)(1)). The experience must be finished before you test. The application fee is $203 and Prov’s exam fee is $100 per attempt.

Proof of at least $300,000 in general liability insurance, filed with DPR as a service request, before the license is issued and at every renewal. A master electrician may plan, lay out, perform or supervise electrical work for lighting, heating or power in any structure.

The Board licenses, by reciprocity, an electrician in good standing from a state whose licensing standards are substantially similar to Delaware’s. From a state whose standards are not similar, you need at least five years of practice after licensure (24 Del. C. § 1409). Maryland in turn accepts Delaware master licenses obtained by exam.

The 2023 NEC. Delaware’s Board of Electrical Examiners says all electrical exams are based on the most up-to-date NEC adopted in Delaware, and the State Fire Prevention Commission adopted the 2023 NEC effective January 1, 2026, with no state amendments. Prov’s last public bulletin, from June 2025, lists the 2020 NEC because that was Delaware’s code then; check the reference list in the bulletin Prov emails you. Every question here cites the 2023 section.

Yes, every Delaware exam is open book and timed. Prov’s bulletin lists the NEC and the American Electrician’s Handbook (17th edition) for both exams, and Ugly’s Electrical References for the master exam. You may highlight, underline in pen and add permanent tabs. Handwritten notes, sticky notes, movable tabs, photocopies and study guides are not allowed. Bring a simple four-function calculator.

No. The State Fire Prevention Regulations adopt the 2023 NEC as published; the only NFPA codes they modify are the fire, flammable liquids, motor fuel, fuel gas, LP-gas and life safety codes. Local inspectors enforce it through electrical inspection agencies the Board approves.

No. Prov’s Delaware bulletin lists no law or business area for either exam and no state law book among the references. Every question is on the NEC, electrical theory and plan reading.

Apply for the license through DELPROS. Once the Board approves you, DPR emails you and Prov sends a registration email within one to two weeks with the Candidate Information Bulletin (check your spam folder). Schedule online at provexam.com/scheduler with your DELPROS application ID, or call Prov at (866) 720-7768. You can test at a Prov site in Wilmington, Newark or Dover, at any other Prov center, or at home through Examroom on weekdays.

You need 75%, a higher bar than most states’ 70%. Prov scores the exam as soon as you finish and reports the result to DPR. If you fail, wait at least seven days to retest; Prov sets no attempt limit on the electrical exams. After two failures within 10 points of passing, you can pay for a 90-minute review of the questions you missed.

DPR can take up to two weeks to receive your score. Masters and limited electricians also submit proof of at least $300,000 in general liability insurance. You can postpone the license fee and insurance for up to 12 months after the exam; after that the Board requires you to test again (24 Del. C. § 1408(f)).

Every two years, with continuing education finished by June 30 of the renewal year. Masters need 10 hours of Board-approved CE, 5 of them on the NEC from the second renewal on; journeypersons need 5 hours on the NEC (24 DE Admin. Code 1400-8.0). Someone licensed less than a year owes no CE at the first renewal. A late renewal costs 50% more.

Neither the Board nor Prov publishes pass rates for Delaware’s electrical exams.
