This design offers sufficient gutter space on sides to allow through wiring and easy lug connection. All enclosures are furnished with hinges, stainless steel quad lead cover bolts and are provided with NEMA 4 gasketing. All covers are removable for clear access to breakers and gutter space. The compact design of rectangular housings permits close grouping on switch racks and other structures. No additional space is required for cover removal except from the front.
