What is an In-situ ground electrode? pick three of the most correct examples a "Rebar Surface; area of Rebar below 900mm is to be not less than 0.4m2 if rebar is 85.5mm in diameter, what is the minimum length L= Area/[3. 14x(D/1000)]; 0.4/[3.14 x (12.5/1000)); = 10.2 m" b. "Steel Piling: Surface area of piling below 600mm is to be not less than 0.2m2; if the piling is 450mm in width, what is the minimum length; L= Area / width/1000) = 0.2/(450/1000) = 0.44 m" c. Water Piping (600mm below finished Grade & 3m in Length) d. "Rebar Surface area of Rebar below 600mm is to be not less than 0.4m2 if rebar is 12.5mm in diameter, what is the minimum length L= Area/[3.14x(D/1000)); 0.4/[3.14 x (12.5/1000)); = 10.2 m" Oe." Steel Piling; Surface area of piling below 900mm is to be not less than 0.4m2; if the piling is 850mm in width, what is the minimum length; L= Area / (width/1000) = 0.2/(450/1000) = 0.44 m" Of. Water Piping (900mm below finished Grade & 3.1m in Length)
