Abstract: Multi-pole and single-pole circuit breakers include a housing and a reset lockout mechanism disposed within the housing. The reset lockout mechanism disables electrical communication between line and load terminals of the circuit breaker if a predefined condition exists. Some circuit breakers include a single actuator, transition between ON and OFF states, and are capable of performing test functions. The test functions may involve testing AFCI and/or GFCI functions of the circuit breakers. The test functions may be performed when the circuit breaker transitions from an OFF state to an ON state. Some circuit breakers including a reset lockout mechanism may be powered only on its line side. Some circuit breakers provide an electrical indication when they are in the OFF state.

Abstract: An interlocked pay off reel comprises square or rectangular endplates that can be interlocked together to build a wall or skid of reels, and which allows the cable to be unspooled or paid out easily using a simple assembly. The pay off reel comprises two round flanges configured to hold respective ends of a cable spool. The flanges can be snapped to respective two square endplates, which elevate the spool and act as a stable base. The engagement mechanism between the flanges and the endplates permits the spool and flanges to rotate during pay off and applies frictional braking to prevent the spool from back spinning and freewheeling. Handles are built into the endplates so that the reel can be handled and moved easily. Interlock mechanisms on multiple sides and surfaces of the endplates permit the endplates to be locked to other endplates in all directions, allowing stacks of reels to be assembled.

Abstract: A cable connector is equipped with a torsion latching mechanism that offers a more positive retention within a jack and is less susceptible to accidental disengagement relative to cantilevered latches. The latching mechanism requires less displacement force to facilitate disengagement of the connector from the jack while maintaining a disengagement action that is familiar to users. The latching mechanism translates a downward pressure applied by the user to a torsion or twisting action that displaces the connector's latch and disengages the connector from the jack.
