NEC Grounding
NEC Grounding
(OP)
Can someone please advise where in the NEC does it state that a customer's ground have to bond with the utility's? Our facility is receiving 12kV distribution voltage and was informed from our utility that we have to utilize their system neutral as a bond to our equipment ground.






RE: NEC Grounding
But regardless of what is in the NEC, you probably will have to meet the utility requirements unless you can show the requirements violate the NEC.
You actually want to connect to the utility ground. It helps reduce your ground resistance and is generally a good idea.
