Use a Megger-type ohmmeter to measure the main cable shield resistance to ground rods. The resistance must
be 5
W
or less.

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

Grounding for Pole Mounted Unit
If the main feeder cable’s shield is bonded to the stub’s shield, the green insulated or bonded
