Downleads or down conductors are The weather of the main conductor procedure that commonly deliver the lightning through the roof level method into the grounding technique. This will involve cable conductor, or experienced steady metal framework of 3/sixteen” thickness or better, or a mix. Reinforcing steel or rebar will not be suitable instead for cable conductor, but Every single cable downlead must be bonded on the structural framing at the top and base of each and every vertical run. All strike termination products should have no less than two paths to ground to separate the lightning together several paths, Hence the smallest building have to have two downleads minimal.
