An electrical enclosure includes gap-free trim plate installation. A switchboard or power panel includes an enclosure face with a central opening covered by a top label plate, a bottom label plate and a plurality of trim plates. The trim plate flanges cooperatively engage one another in an interlocking fashion. The interlocking arrangement allows the trim plates to remain in their installed position without external restraint during installation and removal.

Interlocking trim plates

A panelboard or switchboard enclosure,for a plurality of electrical distribution components,includes a face panel,with an opening,formed in a central portion thereof. A filler plate,extends across the opening,and is secured to the face panel,The face panel,is secured to the frame of a box assembly or cabinet,by fasteners,Releasing fasteners,allows the face panel,and all filler plates to be removed. A first end,of the filler plate,is pivotally secured to the face panel,by a hinge,and a second end,is releasably secured to the face panel,by a fastener,Individual filler plates can be opened by releasing the fastener,and pivoting the filler plate,about the hinge,to reveal the electrical distribution component(s),beneath that filler plate

Trim plate for panelboards and switchboards

A panelboard/switchboard assembly for accommodating bolt-on modules, plug-in modules and lugs. The panelboard/switchboard includes vertical, edge forward bus bars having a plurality of openings formed therein. The edge forward alignment allows plug-in modules to be mounted to the bus bars. The openings in the bus bars receive bolts for mounting straps to the bus bars and for mounting lugs to the bus bars. The openings have a shape having at least one linear element and receive a bolt having an anti-rotation portion with a similar shape. The interference between the opening and the anti-rotation portion of the bolt prevents the straps, and the modules connected to the straps, from rotating.

A compact molded case circuit breaker with increased ampere rating employs a latch assembly for maintaining the circuit breaker operating mechanism in a closed condition against a pair of powerful operating springs. To increase the mechanical advantage required to move the operating handle against the springs, a retractable handle extender is attached to the handle. For higher-rated circuit applications, a lug cover extension is added to the line end of the breaker to assist in extinguishing the intense arc that occurs during circuit interruption and to protect the line lugs from inter-phasal circuit faults. A visual access slot is arranged next to the circuit breaker handle to ascertain and verify the condition of the circuit breaker contacts. The line and load terminal straps are slotted to receive protrusions on the bottom of the line and load terminal lugs and provide anti-turn facility to the line and load terminal lugs under short circuit overcurrent conditions.

A visual access slot is arranged next to the circuit breaker handle to ascertain and verify the condition of the circuit breaker contacts. A rebound cushion is inserted on the interior surface of the circuit breaker cover to deter the return of the movable contact arm during contact separation under extreme overcurrent conditions.
