Abstract: Embodiments provide systems, apparatus, and methods for circuit breaker tripping. Embodiments include providing a circuit breaker with a thermoelectric tripping mechanism, the thermoelectric tripping mechanism including a thermoelectric plate disposed between a current path and a bimetal lever of the circuit breaker; applying a DC current to the thermoelectric plate to heat the bimetal lever; and deflecting the bimetal lever to press upon a trip bar in response to a current overload occurring on the current path. Numerous additional aspects are disclosed.

Abstract: A universal bushing is described herein. The universal bushing can include a base member and a first bushing member. The base member can include at least one outer portion and at least one inner wall that forms a first cavity, where the at least one inner wall has a perimeter that is substantially uniform along a first height of the at least one inner wall. The first bushing member can be removeably coupled to the base member and disposed within the first cavity, where the first bushing member includes at least one first wall having a first inner surface that forms a second cavity and a first outer surface, where the at least one first wall has a first inner perimeter that is substantially uniform along a second height of the at least one first wall, and where the first outer surface forms a first outer perimeter.

Abstract: A cable tray segment is described herein. The cable tray segment can include a first rail substantially parallel to a second rail. The first rail can have a length and include a first coupling portion disposed at a first distal end of the first rail, where the first coupling portion protrudes from the first rail by a distance, and where the first coupling portion includes at least one first coupling feature. The first rail can also include a second coupling portion disposed at a first proximal end of the first rail, where the second coupling portion includes at least one first complementary coupling feature. The second rail can be disposed substantially parallel to the first rail and have the first length. The second rail can be substantially similar to the first rail.

Abstract: A gripping device for gripping a cable and having a first jaw with a first gripping element, a second jaw with a second gripping element, and at least one fastener for fastening the first and second jaws to each other. At least one of the first and second gripping elements has a configuration that makes at least two points of contact with the cable. A system for gripping a cable and having a gripping device fastened to a support structure, where the gripping device has a first jaw with a first gripping element, a second jaw with a second gripping element, and at least one fastener for fastening the first and second jaws to each other. At least one of the first and second gripping elements has a configuration that makes at least two points of contact with the cable.
