Working on a project where we installed a ground ring around the building, from there to the ground buss and metal framing of MCC. From there with a green ground wire to various electrical enclosures ground buss to the metal can.
The engineer says we need to install a panel grounding electrode to the MCC, VFD, PDP tied to site ground.
Is what we did meet the requirements of NEC, article 250?
