When tightening a terminal screw connection with the splice wire, the end of the splice wire should pass around the screw in the same direction as the screw is turned, so that

• 1. The wire will act as a locknut

• 1. Any pull on the wire will tighten the screw

• 1. The wire will not turn off

• 1. The screw can be removed more easily
