Abstract: A weatherproof enclosure 10 with a side hinged cover 36 having a screwless cover latching means 52, which is not defeated by the pressure of expanding internal gases, is disclosed. The enclosure 10 includes a rain channel 76 located immediately adjacent a front edge of the box top 28. The rain channel 76 is generally J-shaped in cross-section and extends across the front of the box 14 and slightly beyond the two side walls 18 and 22 of the box 14 such that any liquid being received within the rain channel 76 will be directed over the side walls 18 and 22 of the box 14. The rain channel 76 cooperates with a downwardly extending flange 40 along the front edge of the box top 28 and an inwardly extending flange 60 along the top of the side hinged cover 36 to prevent the ingress of liquid at the top of the cover 36. Inwardly facing flanges 68 and 72 along the sides of the hinged cover 36 overlap the side walls 18 and 22 of the box 14 to prevent the ingress of liquid along each side of the cover 36.

Abstract: The present invention provides a connector bar for making electrical connections to terminals having a lug body with an externally accessible interior cavity and a binding screw. The connector bar includes an elongated body having two ends and made of electrically conductive material. At least one of the ends having a solid cross-section with a configuration which creates less distortion in the sides of the lug body compared to a round cross-section configuration when the binding screw contacts the end with torque applied for making the pre-determined mechanical and electrical connection. Preferably, the cross-section configuration of the end is defined by a flat top surface larger in width than the contact area of the binding screw, two arcuate sides having an arc value approximately the same as the interior cavity of the lug body, and a flat bottom surface smaller in width than the top surface.

Abstract: A retainer plate is pivotally mounted on a panelboard cabinet door lock housing, which carries a latch for locking the door. A detent on the plate engages in a rabbet opening to enable limited opening movement of the door in response to the pressure developed by arc gases generated by fault currents passing through a tripped circuit breaker in the panelboard cabinet. For ordinary opening movement, the lock latch is manually operated to pivot the retainer plate and disengage the detent from the rabbet opening.

Abstract: The following specification describes a cover for a panelboard with the cover carrying spring biased latch clamp assemblies for engaging the flanges formed on the side walls of the panelboard cabinet.
