What color wire is typically used for attaching to the circuit breaker?

• A. Green
• B. White
• C. Black or red
• D. Blue

Answer: (C)

The standard practice in electrical wiring is to use black or red wires when attaching to the circuit breaker. These colors are designated for hot wires, which carry electricity from the breaker to the load. Hot wires are vital for providing power, and their identification with these colors helps ensure safe and accurate connections in electrical systems. Green wires are utilized for grounding, while white wires are typically reserved for neutral connections. Blue wires are less common and could be used for specific applications, but they do not serve the primary role of connecting to a circuit breaker in general residential or commercial wiring scenarios. Use of black or red wires at the circuit breaker aligns with established electrical codes and practices, making it essential for safety and functionality in electrical systems.
