I have existing switchboard outside building with incoming utility and grounding electrode approximately 10 to 20 feet from building. From the switchboard I have one feeder going into Panel A inside building about 180 feet from existing switchboard.
Do I need to have ground electrodes at Panel A inside building per Nec 2014 Article 250.32?
