South Carolina electrician exam prep
South Carolina licenses electrical contractors, not journeymen. The Contractor’s Licensing Board licenses commercial electrical contractors (the electrical classification of the Mechanical Contractor license) and the Residential Builders Commission licenses residential electricians. PSI gives both trade exams, open book on the 2023 or 2020 NEC until July 1, 2027 and the 2023 NEC after that, each alongside a separate Business Management and Law exam.
