The focus of low voltage exam is on power limited systems such as fiber optic, voice, data, cable TV and satellite…etc. In North Carolina, one needs to have pre-approval in order to sit for the examination. A separate North Carolina Business and Law exam does not exist, but the relevant information is incorporated into the Low Voltage exam. This product does not cover the business and law material. We create 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. This product focuses on the technical aspect of low voltage works in general. It does not specifically cover fire alarm, satellite or other specific disciplines. You should therefore use this product together with other study resources for the best possible exam prep coverage.
