No, low-voltage wire should never be used for 120V applications. It’s not rated to handle the higher voltage or current, which can lead to overheating, insulation failure, or fire hazards. Always choose wire that is properly rated for 120V systems, such as NM-B (Romex) or THHN conductors that meet NEC and UL safety standards. Using the correct wiring ensures both code compliance and long-term electrical safety.
