  1. A “Ufer” ground is slang for what the National Electrical Code (NEC) addresses as a concrete-encased grounding electrode. The term “Ufer” does not appear in the Code, but many in the industry use it. Ufer is the name of the engineer who created it as a solution to significant grounding problems discovered by the U.S. military.
