I have been required to provide a ground for a new telephone service. I understand it needs to be a #6 and attatched to the grounding electrode, but the trailer's main disconnect is mounted on a pole where the utility mounted the service. The main bonding jumper is installed there, my question is can I drive another ground rod at the trailer and attatch it to the equipment grounding bar in the panel at the trailer or just provide them with a #6 to attatch to? I looked at 250-32(D) would this apply?
