Minimum ground wire size

The DSL lines coming into the Stinger MRT can be subject to lightning surges. These
must be discharged to ground through an adequate ground wire. An adequate
ground wire presents a resistance of approximately 0.02ohms to a surge of 500 amps.
The gauges shown in Table D-4 are appropriate for the wire lengths indicated:
Table D-4. Stinger MRT minimum ground wire sizes
Length
0 to 10 feet (0m to 3.05m)
10 to 25 feet (3.05m to 7.62m)
25 to 50 feet (7.62m to 15.24m)
50 to 100 feet (15.24m to 30.48m)
Lucent Technologies does not recommend a ground wire greater than 100 feet long.
