requirements of Clause 6.2. To facilitate electrical bonding to ground of the shield(s), a continuous
uninsulated, uncoated or metal coated, solid or stranded, copper conductor (drain wire) may be placed in
contact with the shield(s). Uncoated copper drain wires shall not be used when aluminum-faced tape is
used as a shield.
