This drawing is for lightning protection system details including air terminal bases, roof conductors, and down lead test links. I’ve included several typical earth pit sections, concrete housing plans, and a huge variety of exothermic welding connections for copper tape and rods. It covers vertical and horizontal layouts for parapet walls and rooftops, incl. tapered steel poles and air rods. These details could be useful in industrial plant electrical design or large-scale commercial rooftop planning.
