What is the minimum wire gauge required for residential lighting circuits?

• A. #12 AWG
• B. #14 AWG
• C. #10 AWG
• D. #16 AWG

Answer: (B)

The minimum wire gauge required for residential lighting circuits is indeed #14 AWG (American Wire Gauge). This size is commonly used for general lighting and receptacle circuits in residences because it can safely carry a load of up to 15 amperes. Using #14 AWG wire ensures that the circuit can handle typical lighting loads without overheating. It's essential to select the appropriate wire gauge to prevent potential fire hazards and ensure the electrical system is efficient and safe. In addition, the National Electrical Code (NEC) outlines the specifications for wiring in residential applications, supporting the use of #14 AWG for lighting circuits. This gauge strikes a balance between flexibility for installation and the ability to adequately handle the expected electrical loads without risk.
