Flange connections provide a direct connection to low voltage switchgear, transformer enclosures and other electrical equipment. Cut out details, dimensions and drilling plans are provided with the customer drawings and it is the responsibility of the switchgear manufacturer to provide the opening, drill fixing holes, connecting hardware and busbar risers in their equipment. For proper coordination between the busbar system and the equipment, detailed drawings, including switchgear phase rotation, must accompany the order. Standard fl anges can be off set to the left or right of the section as required.
