I have a cellular tower site with 5 meters, 1 for local service (lighting) and 4 for future operators.
I have a 50 kva transformer in a pole at the front of the property where the meters are located and the tower site is about 100 yards away.
I have to ground at the meter location according to the POCO and besides the transformer is grounded as well. At the tower we have a complete grounding system designed for the lightning arresters. Less than 1 ohm. There is a structure at the tower site for a main breaker for each of the 5 services.
I bond the neutral to the ground electrode at the meters but do I install 4 cables for each service and keep the neutral isolated at the tower site? Or may I just install three cables and reconnect the neutral to ground at the tower site.
Is there a matter of grounding conductor length that allows me to do this?
Best regards to all
