The roof ring ground system, a Central Office grounding plate, and
building structural steel are examples of valid earth ground
points. If the mounting plate cannot be bolted to a valid earth
ground, or if the mounting plate is to be installed in a nonmetallic
junction box, bolt the mounting plate to a point within 4.6 meters
of the valid earth ground.
