Ernie— I don't see anyone responding to your question and I think that possibly they don't understand the question or some of the terms you are using. I've been in the trade for 45+ years and I thought I understood quite a bit about code and I don't know what you are asking. Hope I'm not the only one. Maybe you could either elaborate or re-word the question or give us more details.
Static Line : Definition A Grounded wire at the Very top of the Pole intended to protect lower conductors from lighting. Impedience Grounding is grounding thur a Neutral Ground Resister.(Limits fault current to ground) see 250.186. My Question : Static line can it be used as a grounding conductor as 250.4 (A) 5 requires. I Know it can't be used as a Neutral.But as a Ground?? Its refered as a Static line on the prints. This apply to a 13.8 & a 4.16 over head & underground Customer owned Feeder.
250.184 Solidly Grounded Neutral Systems. Solidly grounded neutral systems shall be permitted to be either single point grounded or multigrounded neutral. ""For systems over 1000 volts, the Code permits solidly grounded neutral systems that are either single-point grounded or multigrounded systems. For the 2005 Code, 250.184 was reorganized, and new requirements for the installation of single-point grounded systems were added. Circuits supplied from a single-point grounded system are required to have an equipment grounding conductor run with the circuit conductors, and this conductor is not to be used as a conductor for continuous line-to-neutral load.""
