Abstract: A leakage detector is used with a cable tray run configured to support one or more electrical cables. The leakage detector includes an electrical conductor extending around the cable tray run generally transverse to a length of the cable tray run. A magnetic sensor is coupled to the electrical conductor. In use the leakage detector is configured to sense magnetic flux generated by current flowing through the one or more electrical conductors adjacent the leakage detector. More than one leakage detector can be used in a leakage detection system. The leakage detection system may further include a central computing device to determine if there is leakage current from the one or more electrical conductor in the cable tray run based on signals received from the leakage detectors.

Abstract: The present disclosure provides a splice plate including a planar body, first and second pairs of opposing side walls, and a pair of tabs. The first pair of opposing side walls define two parallel slots with one slot engaging a first wire of a first cable tray section and a second slot engaging a first wire of a second cable tray section. The second pair of opposing side walls define at least one slot. A side wall of one of the second pair of opposing side walls engages a second wire of the first cable tray. A side wall of the other of the second pair of opposing side walls engages a second wire of the second cable tray section. One tab of the pair of tabs engages the first wire of the first cable tray section and a second tab engages the second cable tray section’s first wire.

Abstract: A circuit breaker including a case, a trip mechanism, and a trip lever moveable between a first position and a second position. The trip lever includes a first end selectively contacting the trip mechanism and a second end opposite the first end. The circuit breaker also includes a biasing device including a housing coupled to the case and a lever arm coupled to the housing. The lever arm includes an engagement surface in contact with the second end and configured to move between an initial position corresponding to the first position and a final position corresponding to the second position. The biasing device also includes a bias member extending between the housing and the lever arm and biasing the engagement surface against the second end. The lever arm exerts a first torque in the first position and exerts a second torque different from the first torque in the second position.

Abstract: A magnetic trip mechanism for a circuit breaker includes an electrically conductive strap having a first wall portion and a second wall portion that define an interior space therebetween. Also included is a flux block disposed at least partially within the interior space, and movable in response to a short circuit condition of the circuit breaker. Further included is a trip lever operatively coupled to the flux block. Yet further included is a trip latch moveable between a latched condition and an unlatched condition with a handle, wherein rotation of the trip lever occurs in response to the short circuit condition and causes movement from the flux block to actuate the trip latch to the unlatched condition.
