There is no minimum burial depth required for a grounding electrode conductor. Question: Is the conductor connecting the two ground rods (between the electrodes) required to be continuous, without a splice? Can the grounding electrode conductor be run from the service, through the intersystem bonding terminal and down to the first ground rod if it is continuous, without a splice?

Ufer Ground or Concrete Encased Electrodes. Originally, Ufer grounds were copper electrodes encased in the concrete surrounding ammunition bunkers. In today’s terminology, Ufer grounds consist of any concrete-encased electrode, such as the rebar in a building foundation, when used for grounding, or a wire or wire mesh in concrete.

21/01/2009 · I recently inspected a job where a 3phase main panels neutral and ground where tied together and then the grounding couductor went to the grounding electrode. The subpanel was only fed with 4 wires with no grounding conductor but they ran a grounding

ing electrode and the grounding electrode at the service main shows that some current will flow through the earth but the earth is not part of the effective ground-fault current path. The effective ground-fault current path is intended to help remove dangerous voltage from a ground fault by opening the

(2) If the building or structure served has no intersystem bonding termination or has no grounding means, as described in 800.100(B)(2) or (B)(3)(1), to any one of the individual grounding electrodes described in 250.52(A)(7) and (A)(8) or to a ground rod or pipe not less than 1.5 m (5 ft) in length and 12.7 mm (1∕2 in.) in diameter, driven ...

interconnection of the lightning protection system grounding electrodes and other grounded media shall be in the form of a ground loop conductor. 4.14.3 This interconnection shall include all building grounding electrode systems including lightning protection, electric service, communication, and antenna system grounding electrodes.

Grounding electrode conductor connections are an important part of any electrical safety system. These connections ensure the path to ground through any of the grounding electrodes identified in Section 250.52(A). At a recent training session, several questions came up about grounding electrode conductor connections to electrodes.
