Before designing, routing, or installing a down conductor, note that:

  • Use only smooth curves in the installation. The minimum bending radius is 2 cm (0.8 in). The magnetic forces of a lighting current straighten sharp corners - if the material is strong enough to remain in one piece.
  • Never bend the conductor backwards! All routing must be in angles of less than 90º, preferably less than 45º.
  • Make no loops of excess cable! The magnetic forces generated by the lightning current can shred a cable loop into pieces.
