When making a 120V AC connection to a screw, the wire should be circled around the screw post connection in a _________ direction.

When connecting a 120V AC wire to a screw, the wire should be wrapped around the screw post connection in a clockwise direction. This technique ensures that as the screw is tightened, the wire is pulled tighter against the terminal rather than unwinding. The clockwise direction provides a secure connection, as the screw’s motion will effectively hold the wire in place.

Choosing the clockwise direction is particularly important for maintaining good electrical contact and reducing the risk of the connection loosening over time due to vibrations or thermal expansion and contraction within the electrical system. A proper connection helps to prevent electrical hazards, including arcing or overheating, which could arise from a loose or inadequate connection.
