Abstract
A post-mounted device for mounting over an electrical transformer output post extends through an orifice in a wall of the electrical transformer with the post-mounted device having a body positioned on a first side of the wall and a cover positioned on a second side of the wall, with fasteners used to clamp the wall between the body and the cover. The post-mounted device includes a portion that restricts pivotal motion of the cover relative to the wall and a gasket provided in this portion seals the cover against the wall. The cover also includes a stepped cylindrical opening at an end of the cover opposite from the end of the cover that seals against the wall, with the stepped cylindrical opening containing a gasket in its smaller diameter portion for radially sealing against the output post, and a stepped spacer that is partially contained within the smaller diameter portion and partially contained within the larger diameter portion of the stepped cylindrical opening. Elastic washers are provided within the larger diameter portion of the stepped cylindrical opening in the cover in order to provide a compressive load against the stepped spacer.
