A ball is wired if it was placed there by the opponent and cannot see all parts of at least one ball. The striker must be able to strike the ball with all parts of his mallet face and not have an obstructed swing. If a wiring contact is not take in the first turn when it arises the player becomes responsible for that ball's position. In a wiring decision only balls upon which the wired ball is live are considered. If the next ball to play is 3-ball dead it is considered to be open to a ball for the purposes of a wiring decision.
All balls are relevant in a wiring decision.
