When used with AC cable or Greenfield, Anti-Short ® bushings protect the wires from being chafed by the roughs end of the armor at the point of connection. NEC article 333-9 requires their use on AC (armored cable). They are placed between the outer metal armor and the conductors forming a protective shield at the point where the wire is bent during final connection. In the trade, they are referred to simply by their sizes 0 through 8 depending on the size of the cable or Greenfield.
