International Classification:

F21V 3300

US Classification:

362 95, 362154, 362564, 362375

Abstract:

A service unit provided with a door having an evenly illuminated lens is disclosed. The service panel, typically containing at least one outlet, provided behind the door further preferably includes a socket for receiving a lamp. The lamp used in the present invention preferably directs light towards a bottom side of the unit, in a direction across the lens when the door is in a closed position, such that the light is evenly distributed across the lens. The door includes an opening for receiving the lens that is further preferably provided with an indented lip recessed from the front surface of the door such that the lens lies substantially flush with the front surface of the door. A plastic rivet may secure the lens to the lip, as may a bead of adhesive along the lip. The lip is preferably not present along the top side of the opening for allowing the top side of the opening to serve as a rain shed for the lens. The lens may include an alphanumeric symbol for identifying a particular camp site.

US Classification:

174 67, 174 66, 174 50, 174 53, 220 32, 220 38

Abstract:

A removable cover for a an electrical component box includes a pair of side walls having hinge edges including a hook and an engagement surface extending from the hook. The hook slides over and engages the hinge members of a box, and the engagement surface forms a sliding surface that allows rotation of the cover about the hinge elements. The hinge is easily installed and removed by orienting the cover at a selected angle relative to a longitudinal axis of the box, and lifting the hook over the hinge member to either engage or disengage the hook from the hinge members.

International Classification:

H01H 7500

US Classification:

335 6, 335 8, 335 11, 335 13

Abstract:

A neutral pole for a multipole circuit breaker is disclosed. The circuit breaker includes a housing, a plurality of contact arms for opening and closing an electrical circuit, and an operating mechanism for driving the contact arms. The neutral pole includes a neutral housing, a conduction path within the neutral housing having a neutral arm arranged to open and close the conduction path, a bias spring configured to exert a first bias moment on the neutral arm when the conduction path is closed, a spring support configured to support the bias spring, a rotor pivotally arranged within the neutral housing and configured to displace the neutral arm and to open the conduction path, and a drive pin configured to couple the rotor to the multipole circuit breaker. The spring support is fixedly arranged at the neutral housing. The rotor is responsive to the opening and closing action of the operating mechanism of the multipole circuit breaker.

US Classification:

335 16, 361115, 361 939

Abstract:

An apparatus for interrupting an electrical short circuit current in an electrical distribution system having a plurality of phases is disclosed. The apparatus includes a housing, a plurality of separable conduction paths, an operating mechanism in operable communication with the plurality of conduction paths, an electronic trip unit in signal communication with each of the plurality of conduction paths and in operable communication with the operating mechanism, and an electromagnetic trip unit in signal communication with each of the plurality of conduction paths and in operable communication with the operating mechanism. The electromagnetic trip unit is configured to be operably responsive to a first half-cycle waveform of the short circuit current prior to the electronic trip unit being operably responsive to a second multi-cycle waveform of the short circuit current.
