An aluminum air terminal is positioned within two feet of each outside corner atop the mechanical unit, connected to an aluminum main conductor routed with adhesive cable fasteners spaced at three feet maximum. The conductor path maintains a horizontal or downward trajectory to avoid upward loops, with minimum eight-inch bend radii and ninety-degree minimum bend angles. An adhesive aluminum base is adhered directly to the top of the unit. An aluminum bonding plate secures the conductor at the base of the unit, and all penetrations are sealed with silicone sealant.
LIGHTNING CABLE SHALL REMAIN IN A HORIZONTAL OR DOWNWARD PATH AVOIDING "U" & "V" POCKETS (DOWN & UP). NO BEND OF A CONDUCTOR SHALL FORM AN INCLUDED ANGLE OF LESS THAN 90 DEGREES OR HAVE A RADIUS OF BEND LESS THAN 8 INCHES.
