Current PSI format: the Louisiana Electrical Statewide Contractor exam contains 100 questions, a four-hour time limit, and a 70% minimum passing score. The examination is open book and currently uses the 2023 National Electrical Code, OSHA construction safety material and Ugly's Electrical References.
What Is the Louisiana Electrical Statewide Contractor Exam?
The Louisiana Electrical Statewide examination is the contractor trade exam connected to the state's Electrical major classification. It measures whether a qualifying party can apply electrical-code rules, trade knowledge, installation requirements, calculations, construction safety standards and approved reference materials under a strict time limit.
The current PSI outline contains 100 questions. Six categories each contain 10 questions, which means those six high-volume subjects make up 60% of the current examination. That makes them a smart place to concentrate your early contractor exam prep.
Exam answer: 100 questions, 240 minutes, 70% minimum passing score, open book, 2023 NEC, OSHA 29 CFR Part 1926 and Ugly's Electrical References.
Licensing answer: Louisiana contractor licensing is handled through the Louisiana State Licensing Board for Contractors. Electrical projects exceeding the state's current electrical-project threshold require the appropriate commercial contractor license.
The exam is broader than basic code lookup. Candidates should prepare for services, feeders, branch circuits, grounding and bonding, conductors, raceways, overcurrent protection, special occupancies, motors, transformers, lighting, signs, communications and safety.
This page combines information from 3 primary authority groups and 7 visible secondary research groups. Current PSI and Louisiana licensing information controls when older commercial exam-prep pages show different exam numbers.
