An underground concrete ductbank profile measuring one foot four inches wide by ten inches high contains three conduits arranged with specific spacing. A three-inch neutral ground conductor conduit and a three-inch spare conduit sit on the lower level with three and a half inch typical spacing from edges, while a one and a half inch current transformer wiring conduit is positioned above them. A legend defines the conduit designations for the neutral ground conductor, spare, and current transformer wiring.
