Recreational Vehicle (RV) Technician Practice Test

When making a 120V AC connection to a screw, the wire should be wound around the screw post connection in which direction?

1. Counterclockwise

2. Clockwise

3. Either direction is acceptable

4. In a zigzag pattern

The correct answer is: Clockwise

When making a 120V AC connection to a screw, the wire should be wound around the screw post connection in a clockwise direction. This is because when the screw is tightened, it will pull the wire tighter against the post, ensuring a secure and stable connection. Winding the wire in a clockwise direction allows the screw to clamp down on the wire effectively, helping to prevent the wire from becoming loose over time, which is crucial for safe and reliable electrical connections. The technique of winding in this manner also adheres to common electrical practices, as most electricians are trained to make connections that tighten in the same direction as the winding of the wire. This helps maintain a consistent methodology in wiring practices, promoting safety and efficiency in electrical installations. Moreover, connections that are consistently made in this way can minimize the risk of accidental disconnection or short circuits, contributing to overall electrical system integrity.
