摘要: An improved panel board construction is described, including an extruded insulative base pan which slidably engages at least one main-line bus bar and a neutral connector element and which has a plurality of electrical contact points. The base pan also prevents current flow through the base pan between any two of the contact points of the main-line bus bars. A protrusion extending from the base pan having a tortuously formed surface thereon prevents current flow through the base pan. The panel board is provided with interchangeable main-line lugs which may be used to directly contact the main-line bus bars or, alternatively, support a main-line circuit breaker between the lugs and the main-line bus bars. The base pan is symmetrically formed by an extrusion process so that it may be adaptable for use with a variety of panel board sizes simply by shearing the base pan to form the appropriate length.

摘要: A one-piece, slam-type latch for snap-in installation in an orifice of a door is provided for maintaining the door in a closed position relative to a door frame having an extending keeper means. The latch includes a first portion having a generally rectangular configuration, and a second portion extending normally outward from the first portion for insertion through the orifice. One end of the second portion is in integral attachment with one side of the first portion. The other end of the second portion is provided with at least one indentation for interlocking engagement with the keeper means. A leaf spring is integrally attached to the second portion and extends angularly from the second portion toward the first portion. The latch is further provided with a third portion in integral engagement with the first and second portions. The third portion extends planarly outward from the first portion. The third portion has an auriculate recess provided with a first lobe extending inwardly toward the first portion and a second lobe extending planarly opposite the first lobe to define a thin-walled section of the third portion. The thin-walled section of the third portion is sufficiently pliable so that the third portion may be deformed.
