Book updated Apr 2024. The focus of low voltage exams are always on power limited systems such as fiber optic, voice, data, cable TV and satellite...etc. In Georgia, it is the Georgia Construction Industry Licensing Board that administers low voltage work licensing. There is a Division of Low Voltage Contractors, with exams available at different levels. We create these self-practice test questions referencing NEC established technical standards (as well as a little bit of state specific licensing/OSHA requirements) currently valid in the trade. Each question comes with an answer and a short explanation which aids you in seeking further low voltage related technical information.
