Question: Where I am located the ufer consists of the required amount of rebar encased and it is then turned up to extend through the basement floor, on the interior of the building, for us to attatch to at a later date. Does the connection to that rebar need to be encased in concrete or can it be exposed in the unfinished basement area? 250.52 A 3 1 makes no mention of this but 250.52 A 3 2 says metallic components. clamps I guess, must be encased when the #4 is the electrode.
Connections to the rebar "turned up" do not need to be encased.250.52(A)(3)(1) states the Electrode shall be of sufficient length to connect to grounding terminals of the equipment and to extend into the concrete floor or foundation at least 300 mm (12 in.).
250.52(A)(3)(2) states Metallic components of the concrete encased electrode, such as reinforcing steel, steel forms, metal lath, etc., shall be electrically connected to one another to provide a continuous electrical path.Hope this helps. Flag for review
