A circuit breaker assembly includes a circuit breaker including a housing and a handle extending from the housing, with the handle being movable between an on position and an off position. The assembly includes a handle mechanism connected to the housing of the circuit breaker. The handle mechanism includes a base, a slider slidably connected to the base and including first and second spaced apart arms with the handle of the circuit breaker at least partially between the first and second arms, and a spring on the slider. The slider is movable between a first position with the handle in the on position and a second position with the handle in the off position. The handle engages the spring with the handle in the on position and the slider in the first position.

A rotary motion switching apparatus is usable with a circuit interrupter and employs an attachment system in order to resist removal of the rotary motion switching apparatus from the circuit interrupter. The attachment system has three connectors that are engaged with an exterior surface of a housing of the circuit interrupter. The portions of the housing that are engaged by the three connectors are pre-existing portions of the exterior surface of the housing of the circuit interrupter.

Housing

A rotary motion switching apparatus is usable with a circuit interrupter and employs an attachment system having a pair of connectors that are received in a pair of openings formed in a housing of a circuit interrupter and that are affixed to the housing within the openings in order to resist removal of the rotary motion switching apparatus from the circuit interrupter. The openings are pre-existing in the housing of the circuit interrupter and are provided to enable access by tools with terminals of the circuit interrupter to which load wires and the like are connectable. The connectors thus secure the rotary motion switching apparatus to the circuit interrupter by using openings that are already formed in the circuit interrupter and thus the rotary motion switching apparatus is usable without requiring a modification to the housing or to the molds that are employed to form the housing.

A rotary motion switching apparatus is usable with a circuit interrupter that is situated in a NEMA box or other box and employs an attachment system. An access port that is formed in a wall of the NEMA box or other box permits a shaft having a handle at an end thereof to be connected with the rotary motion switching apparatus. The rotary motion switching apparatus includes a universal joint on a rotational component that enables operation of the handle and shaft without binding on the wall of the NEMA or other box even if the access port in the box is offset from an axis of rotation of the rotational component.

Circuit interrupters such as breakers with a metal arc chute having a base and sidewalls extending outward from the base forming an open cavity, a movable arm holding a movable contact adjacent to the arc chute, a line conductor electrically connected to a stationary contact residing adjacent to the arc chute facing the movable contact and a three-dimensional molded arc quenching insert attached to the metal arc chute, and residing in the cavity of the metal arc chute between the stationary and movable contacts. The insert has an arc quenching material that optionally releases a gas such as hydrogen during an arcing event.

An electrical receptacle assembly is for a power inlet apparatus of an electrical system. The power inlet apparatus includes a housing. The electrical system has a power source and a transfer switch. The electrical receptacle assembly includes an electrical receptacle structured to be mechanically coupled to the housing and electrically connected with the power source and the transfer switch, and an indication assembly mechanically coupled to and electrically connected with the electrical receptacle. The indication assembly has a status indicator adapted to provide an indication of circuit status within the electrical system.
