The important idea is keeping the shield at a defined electrical reference to minimize noise and potential differences near power equipment. When a shield runs close to power conductors, it can pick up voltages from those conductors through capacitive or inductive coupling. Bonding the shield to the power neutral within a close distance provides a stable reference and a low-impedance path for any induced currents, reducing the likelihood that the shield itself will carry stray voltages or become a noise source for the communications cable.

The recommended distance is 1.83 meters (6 feet). If the shielded run is within 6 feet of power apparatus, bonding the shield to neutral helps keep the shield at the same potential as the power system, improving safety and EMI performance. Distances beyond 6 feet are not covered by this same bonding requirement, which is why the correct choice is 1.83 meters.
