Abstract: An electrical outlet box has electrical power cable entry ports in which one or more closure panels are each mounted adjacent the rim of the aperture along one edge portion only of the panel, the remaining portion of each panel being free and extending substantially across the aperture in a direction angularly inwardly from the plane of the aperture. The closure panels are each either hingedly mounted or sufficiently flexible and resilient so as to be self-opening, such that each free end portion is deflected away from the opening upon passage of the cable into the aperture by manual force, and thereafter resistingly bears against the installed cable. Each panel may be tapered so as to have increased thickness at the base, in which case the panels are self-clamping against removal of the cable from the aperture, and may include supplementary cable gripping projections on their outwardly facing surfaces.

Abstract: The structure according to the invention includes a pair of flange members depending angularly towards each other from opposite sides of each electrical power cable entry port formed in a sidewall portion of an electrical outlet box, with each pair of cooperating flange members adapted to enable essentially complete closure of the cable entry port. According to one aspect, each cooperating pair of flange members comprises a pair of cable grasping detent flanges, each spaced from its corresponding wall portion by a base-like projection to accommodate an entry port closure panel. According to another aspect, the inward edges of each cooperating pair of flange members are coupled together to close the cable entry port which may be formed with a portion extending into the backwall, with a rigid flange depending from the sidewall portion and extending parallel to the front edges of the flange members.

Abstract: An electrical outlet box having wall areas recessed inwardly from the outermost periphery of the box wall structure, the recessed areas housing pawl mounting devices and electrical power cable entry ports. The cable entry ports have self-opening and/or self-clamping closure panels extending angularly inwardly from the rim of the port which are also self-centering and self-adjusting for different cable sizes.

Abstract: At least one stationary electrical contact is fixedly mounted in a housing and an equal number of corresponding movable contacts is affixed to a movable member pivotally mounted within the housing and positioned thereon to mate with the stationary contact, however, first biasing means are coupled between the movable member and the housing to retard mating of the contacts. An actuating member is slidably pivotally mounted within the housing and adapted to engage the movable member, with biasing means coupled between the actuating member and the housing to overcome the first biasing means and urge the movable and stationary contacts into mating relation when the actuating and movable members have been engaged. Release means, controlled by circuit fault sensing means, are positioned adjacent the actuating member for causing the actuating arm to be released from the movable member when predetermined circuit conditions are detected by the sensing means, to disjoin the stationary and movable contacts.
