Which line should always be connected to the silver screw on a 120v outlet?

• A. Ground line
• B. Hot line
• C. Neutral line
• D. Return line

Answer: (C)

The correct answer is the neutral line, which should always be connected to the silver screw on a 120v outlet. In standard electrical wiring for outlets, the silver screw is designated for the neutral wire. The purpose of the neutral wire is to provide a return path for electrical current back to the power source. Understanding the role of the neutral wire is crucial for safe electrical installation and compliance with electrical codes. The neutral wire completes the circuit by carrying current away from the device back to the panel, which is why it is connected to the silver screw. Properly wiring the outlet ensures that devices operate safely and effectively while minimizing the risk of electric shock or fire hazards. Each screw color on an outlet serves specific functions: the gold screw is typically for the hot wire, while the green or bare screw is for the ground connection. Identifying and using these connections correctly is essential for maintaining safety in electrical installations.
