Abstract
Abstract A connector for mounting on a vertical main frame has an elongate body portion containing a protector field and an elongate jumper field extending along one side. The connector is mounted on the frame member by a bracket which mounts the connector so that the body portion extends at an angle to the plane of the main frame. With an appropriate angle, a useful space is provided between connectors, for access, while removal and replacement of protector modules, and entire connectors, is readily available. One particularly appropriate angle is about 53°, while another is about 70°, although these can vary. A test field can also extend along one side, adjacent to the jumper field.
