7

If commercial power ground exists, bond telephone ground to power ground as a safety measure.

8

Using a Megger-type ohmmeter, measure the main cable shield resistance to ground rods. The resistance must
be 5

Ω

or less.

9

If the resistance requirement is not met, ground the main cable shield every 2,000 ft (610 m).

Figure 6.

Grounding for Pole-mounted Unit

If the main feeder cable’s shield is bonded to the stub’s shield, the green insulated or
bonded stub shield wire should be disconnected from the metal card cage base. This is
recommended to reduce service affecting noise from being injected into the doubler
circuits from circulating ground loop currents, and to help inhibit corrosion.
