Copper Applications Lightning protection and robust grounding essential for steeples, roof structures A Case Study A Tale of Two Churches Photo curtesy of Richmond Times-Dispatch The near-total destruction of Richmond, Virginia’s historic St. James Episcopal Church by a 1994 lightning strike is believed to have resulted when the strike hit the ungrounded, copper-clad steeple, from which energy traversed the wooden roof structure, setting it ablaze, rather than being directed safely to earth. An alternative explanation sees the strike initially contacting a distribution transformer behind the structure. www.copper.org www.copper.org
