Abstract: A cable tray assembly comprising a plurality of tray segments, each tray segment comprising a first portion and a second portion positioned about first and second ends, respectively, of the tray segment. The first portion has an inner region between at least sidewalls of the tray segment that is sized to receive placement of a second end of another tray segment. Additionally, the first portion can include one or more open ended grooves that, during assembly of the cable tray assembly, can receive a mating projection that is securely connected to the second end of the other tray segment. The open ended groove can be downwardly sloped, and can extend through an outer edge of the corresponding sidewall. The projection can be fixed or adjoined to the second end at least prior to assembly of the cable tray assembly, and can include shank that is threadingly engaged by a retainer.

Abstract: A joint strip including a center trunk, at least one recess formed by at least one upper flange and at least one lower flange for use in bridging a gap in sheet metal, such as in cable trays, cable tray covers, or two pieces of sheet metal. The joint strip may include more than one recess. The one or more recesses are configured to accept, for example, a cable tray surface located at a gap between two cable trays. The joint strip can be inserted between cable trays, for example, without disconnecting the trays from each other or removed in existing cable trays without separating adjacent sections of cable tray or cable tray covers.

Abstract: A hold-down clamp for holding a cable tray on a strut channel includes a main body member extending between first and second ends, opposed side walls extending downwardly and perpendicularly from the main body member, and first and second side members extending from each of the opposed side walls. The main body member has a first end defining a clamp engagement portion and a second end defining an expansion guide portion. Each of the first and second side members includes a flange having a clamp engagement structure, a planar middle structure, and an expansion guide structure that are integrally connected to each other, and a clamping tooth, which is defined between the clamp engagement structure of the flange and the side wall such that the clamping tooth transitions into the clamp engagement structure of the flange and the side wall of the hold-down clamp.

Abstract: A vented exhaust system for an electrical cabinet housing high voltage equipment. Very short-time explosions can occur within the electrical cabinet that are the result of a short circuit of the equipment housed within. The vented exhaust system provides for a way to safely release the pressure and hot gasses that can result from the short circuit so that the cabinet does not explode.

Abstract: A new connector for attaching conductor wires to a metersocket is disclosed. The design of the connector allows the wires to be laid in along the side of the connector and requires little bending and slack in the wire. Once seated in place, the connector can be secured using a set screw that keeps the conductor wire in place.

Abstract: A reinforcing structure is provided for supporting a joint of two cable tray sections, wherein each of the two cable tray sections includes a side rail having a planar body member, a bottom edge and a top edge, and wherein the joint is positioned over a structural support member. The reinforcing structure may include a top member; a body member extending substantially perpendicularly from the top member; and a bottom member extending substantially perpendicularly from the body member. The bottom member may be configured for mounting on the structural support member. The bottom member may be configured to receive the bottom edge of the side rail. The top member may include an inside edge configured to support the planar body member of the side rail when the bottom edge of the side rail is received into the bottom member.

Abstract: A grounding clamp for securing a grounding cable to a tray having a number of spaced apart longitudinal and transverse members includes a body portion having a bottom portion and inner and outer end portions projecting from the bottom portion. The inner end portion includes at least two finger-like members projecting from the bottom portion for engaging at least one transverse member between the finger-like members. A portion of the body portion includes a cavity defined by the bottom portion, the inner end portion, and the outer end portion for receiving at least one longitudinal member therein. The cavity further receives the grounding cable. The outer end portion includes a threaded opening therethrough. The grounding claim further includes a threaded bolt that is received in the threaded opening in the outer end portion for securing the grounding cable to the at least one longitudinal member.
