The correct choice is that the stripped lead should be looped in a clockwise direction when installing a conductor on a side-wired device. This technique is essential for ensuring that the connection is secure and reliable. When the conductor is looped clockwise, it follows the natural motion of tightening the screw on the terminal. As the screw is turned to tighten, it pulls the conductor tighter against the terminal, minimizing the risk of it becoming loose over time due to vibration or thermal expansion.

In contrast, if the conductor were looped in a counter-clockwise direction, tightening the screw could inadvertently push the loop away from the terminal instead of securing it, potentially leading to a poor connection, increased resistance, or even arcing, which could cause a failure of the device or create a safety hazard. Therefore, consistent looping in the clockwise direction enhances both the safety and effectiveness of electrical installations.
