Hello.
Question is in regards to grounding at a residential house. There is an Intersystem Bonding Termination (basically a connection node) next to the meter, that is connected to the grounding electrode(s). Conductors are terminated to it from 2 communication systems, the meter base, and from a liquid propane tank. There is no conductor from the main circuit breaker panel to the grounding system. Though the neutral and ground bus bars are bonded at the main circuit breaker panel, and of course the neutral is connected back to the meter base. I did not get to look inside the meter since it was locked by the utility company and they were not on site. I believe the ground conductor is connected to the neutral inside the meter. My question is, is this an acceptable configuration of grounding the electrical system? Being that there is no designated ground conductor from the circuit breaker panel to the grounding electrode, only the neutral conductor. Also, where in the NEC can I find wording to support this configuration? For context, we want to make sure the liquid propane tank is grounded correctly to the electrical system for surge/lightning protection. There is no disconnect panel or any other circuit breaker subpanels in this system; conductors are from the serving transformer to the meter base, to the main circuit breaker panel, then out to the loads.
Please let me know if I need to clarify anything further.
Many Thanks,
Doug
