Under what circumstances would you install an antishort bushing and what steps are involved in the installation?
What will be an ideal response?
Whenever a connection is made in an outlet box or a switch box using armored cable, it is necessary to cut the metal armor back 6 to 8 inches from the end of the cable. To prevent any damage to the conductors, a fiber bushing must be inserted between the steel armor and the wires at the point where the armor is cut. Installation involves three steps: 1) Cut armor and slide it off; 2) Insert bushing between paper wrapper and armor; and 3) Untwist conductors and tear off paper close to bushing.
