DE Electrician study guide
DE Electrician · Work through your exam, one topic at a time.
The Delaware Electrician credential is issued by the Delaware Division of Professional Regulation, the Department of State agency whose stated mission is "to credential qualified professionals to ensure the protection of the public's health, safety, and welfare." Electrician appears on the Division's published list of professions and is grouped under its Construction category, alongside trades such as Plumbers, HVACR, Home Inspectors, and Elevator Mechanics. The credential is aimed at electricians who perform or supervise electrical work in Delaware and who must therefore hold a state-issued license rather than rely on local registration alone. Because the Division publishes the Electrician profession page, applications, renewals, and license verification all run through its online system, DELPROS. Candidates should treat that profession page, the Guide to Information, and the DELPROS instructional videos as the authoritative sources for application steps, renewal, and status checks. The DE Electrician study guide has 4 sections and about 1,735 words.

This domain covers Delaware's licensing statute, Board rules, license scope, and the permitting and inspection environment in which electricians work. The Delaware exam tests the state's own licensing statute and rules, not just the NEC.
432 words, about 2 min02Electrical Theory and Principles
This domain tests the physical math behind code rules: Ohm's law, power, series and parallel circuits, AC reactance and impedance, power factor, three-phase relationships, transformers, and voltage drop. Expect calculation items and concept items that ask why a conductor, overcurrent device, or neutral behaves as it does.
481 words, about 2 min03National Electrical Code Application
This domain tests code navigation and application: finding the correct article, applying definitions and exceptions, and performing code calculations. The exam assumes a current NEC edition; local amendments can change the answer, so read the question's jurisdiction.
