Earth Ground Location Guidelines
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 m of the valid earth ground.
