DRAINAGE PLANE  A. All penetrations are adequately protected with butyl flashing tape or correctly sized rigid type flashing panels and flanged components and adequately supported by the sheathing.  B. Electrical wires should be sealed from the bottom and top with butyl flashing tape.  C. When installed, flashing panels or flanged components are sealed to the sheathing on the sides and top.  D. All flashing tape is pressed flat, provides a tight seal around the flashing panel and covers any fasteners penetrating the flashing panel. Install additional seam tape where required per manufacturer installation instructions.  E. Horizontal trim pieces and ledger boards attached through the water-resistive barrier (WRB) have drip caps sealed to the sheathing and turned up or down at the ends.
